Assembly.Load Can't Load My Custom Assembly From The GAC.

Mar 7, 2007

Hi there.

I have an assembly, call it A1, that I've deployed to a SQL Server 2005 database. I can use the managed stored procedures from A1 in SQL Server no problem.

In A1 there is a bit of code which uses the Assembly.Load() method, so load another assembly and use instances of class found in that external assembly. However, when I run the managed stored proc in A1 that uses Assembly.Load() I get the error:

Could not load file or assembly 'A1, Version=1.0.0.0, Culture=neutral,PublicKeyToken='????' or one of its dependencies. The system cannot find the file specified.

(note: for security I've changed some of the above line).

So I changed the Assembly.Load() to use

System.Data,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089

I re-built the project, re-deployed it and ran the code in SQL Server - it worked. I could create an instance of a System.Data.DataSet for example. So why can't I load my own custom assembly? My assembly does have a strong name and it's installed in the GAC. I wrote a console app to try and Assembly.Load() my custom assembly and that worked fine (it was also running on the same server as the SQL Server).

So it's defiantely the SQL Server that can't 'see' my customer assembly. What do I need to do this assembly so that SQL Server will allow me to Assembly.Load it, just as it can with System.Data?

Thanks
Jas.

Failed To Load Expression Host Assembly. Details: StrongName Cannot Have An Empty String For The Assembly Name.

Jan 12, 2006

I previously had an ASP.NET 1.1 site running on my IIS 6.0 server (not the default website) with Reporting Services running in a subdirectory of that website.  I recently upgraded to ASP.NET 2.0 for my website and was greeted with an error when trying to view a report.  The error was very non-descript, but when I checked the server logs, it recorded the details as "It is not possible to run two different versions of ASP.NET in the same IIS process.  Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process."

 

First of all, I could not figure out where and how to do this.  Secondly, I decided to try to also change the Reporting Services folders to run ASP.NET 2.0 and when I did, I was greeted with the following message when attempting to view a report:

 

"Failed to load expression host assembly. Details: StrongName cannot have an empty string for the assembly name."

Please help.

Reporting Services :: Could Not Load File Or Assembly Error On Adding Custom Libraries In SSRS Reports

Sep 21, 2015

I have created a custom library(CodeLibrary) which internally references the dlls Microsoft.TeamFoundation.Client and Microsoft.TeamFoundation.WorkItemTracking.Client.

I added this custom Dll codelibrary.dll to my SSRS report. and the expression of one of the field as 

=codelibrary.codefunction.GetValue(1000)  
codefunction is the class and GetValue is the method.

When I preview the report, I get the error "Error while loading code module:

'CodeLibrary,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null'. Could not load file or assembly 'CodeLibrary,Version1.0.0.0, Culture=neutral,PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified."

I am using VS2013, I have placed the custom library DLL in the path

C:Program FilesMicrosoft Visual Studio 12.0Common7IDEPrivateAssemblies

I have tested the custom library with a WPF application and it works fine.

I am not able to figure out what is causing this error.

Could Not Load System.EnterpriseServices Assembly

Nov 1, 2007

Guys, this the first time I got this message

TITLE: Connection Manager
------------------------------
Test connection failed because of an error in initializing provider. Could not load file or assembly 'System.EnterpriseServices.Wrapper.dll' or one of its dependencies. The system cannot find the file specified.

This happens whenever I press "Test Connection" button in the Connection Manager dialog. I'm wondering if this has something to do with the installation of the .NET Framework. I'm using a new machine and so far I havent had any problem with .NET applications. Do I need to add this assembly somewhere?

Could Not Load File Or Assembly SQLXMLBULKLOADLib

May 30, 2006

Greetings,

I'm in the process of migrating several SQL Server 2000 DTS packages to Integration Services packages. One of the old 2000 DTS packages used the SQLXML Bulk Loader component. In order to use the new SQLXML 4 COM object in my Script Task (to initiate the Bulk Loader using .NET code) I've used the tlbimp.exe tool to create a .NET wrapper DLL. I've placed the DLL in the appropriate directory (C:Program FilesMicrosoft SQL Server90SDKAssemblies), successfully added it to my project (with Intellisense working), but when I run the package it fails with the following error:

Could not load file or assembly 'SQLXMLBULKLOADLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

Note: I also tried placing the DLL in C:WINDOWSMicrosoft.NETFrameworkv2.0.50727 with no prevail.

I've confirm the file exists (and any dependencies) in their appropriate locations. Has anyone else run into this? Any help is much appreciated.

Thanks, Shaun

Could Not Load File Or Assembly To Server

Nov 29, 2007

Hi,
I have a custom library (ReportLibary.dll) and ı added it as a reference to the report (Report.rdl). I also copied the dll file to ..IDEPrivateAssemblies. The report uses a methot from the dll to get some data.
When ı run the report from my local computer there is no problem, the data is generated from the dll. But when I depoy it to the sever an exception occurs.

"Error while loading code module: €˜ReportLibary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null€™. Details: Could not load file or assembly 'ReportLibary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Can not find the file. d:...Report.rdl"

Load Assembly From Stored Procedure

Jan 26, 2006

Hi,

Is it possible to load an assembly either from a byte array or from the disk at runtime from a CLR stored procedure.

I
have created a stored procedure that needs to load different assemblies
depending on a query and then invokes a method (called execute() passing a string query as a parameter).



From debugging the CLR stored procedure in .NET I have found that it is this line that creates an error:



    Assembly myAssembly= Assembly.Load()  

It
doesnt matter if I attempt to load the assembly from it's byte array or
from a file location, it always gives the following error:


Msg 6522, Level 16, State 1, Procedure runQuery, Line 0A .NET Framework error occurred during execution of user defined routine or aggregate 'runQuery': System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.System.IO.FileLoadException:   
at System.Reflection.Assembly.nLoadImage(Byte[] rawAssembly, Byte[]
rawSymbolStore, Evidence evidence, StackCrawlMark& stackMark,
Boolean fIntrospection)   at System.Reflection.Assembly.Load(Byte[] rawAssembly)   at ClientInterface.RunInterface(String queryName, String parameters, String& returnValue)



It works perfectly if I run it using a mock up front end app it just seems to be sql server that doesnt like it.

Anybody have any ideas?

Could Not Load File Or Assembly ADODB, Version=7.0.3300.0

Jan 26, 2006

I have an application broadly deployed
(about 10 computers). As of yesterday, two of these computers are
unable to start the application, and failing with the error below. All
other computers run the application just fine.



System.IO.FileNotFoundException: Could not load file or
assembly 'ADODB, Version=7.0.3300.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot
find the file specified.
File name: 'ADODB, Version=7.0.3300.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'



I checked and ADODB.dll version 7.0.3300.0 is in the GAC in the deployment target machines.



I find ADODB.dll in my C:Program FilesMicrosoft.NETPrimary Interop
Assemblies folder (development computer), but this is version
7.10.3077.0 (file properties version)



I see ADODB.dll as a project reference, but this shows version
7.0.3300.0, and shows the path to the PIA folder. I have no clue why
these are not showing the same version number. Local Copy is false.



Installing MDAC 2.8 on the failing deployment target machines did not help.



Any clues or ideas or things to try??

Unable To Load An Assembly With Permission Set = EXTERNAL ACCESS

Jul 20, 2007

Hi



I've loaded a C# assembly into my database with External Access (the dll contains a routine

that accesses Environment.MachineName).



I am now unable to invoke any of the entry points in this assembly. I get the error message



'An error occured trying to load assembly Id XYZ. System.IO.FileLoadException.....'



I have set the database Trustworthy flag to ON and the assembly does not have a strong name.



Can anyone tell me what I've done wrong?



Thanks

Steve



P.S. I am calling the assembly from SQL code residing in a different database than the one

the assembly has been loaded into.

Could Not Load File Or Assembly 'Microsoft.Data.Odbc...

I have developed an application in C#, and it uses both a SQL server database, and as part of its operation it opens up a Foxpro database. I am using Odbc to connect to the fox pro database and everything wortks just fine on my devleopment machine. However when I deploy my application I am getting the following error text when ever I create the form that does the Odbc work.

************** Exception Text **************

I have absolutely no clue why I am getting this error. I have insured that the latest MDAC was installed ( it is XP Pro so no updates there ) I have made sure that I have the latest Fox Pro Odbc driver installed as well and I can create the DSN just fine.

Can anyone point me where to look next ? Im truly stumped here.

Cannot Load Dynamically Generated Serialization Assembly SQLCLR

Apr 10, 2008



In article http://support.microsoft.com/kb/913668 it says to generate a serialization assembly and pop this into the database along side the assembly with the serialized type. All well and good, but how doe the XmlSerializer know to look in the database for the assembly - does it use the name of the assembly + XmlSerializer?

It is certainly ambiguous in the aforementioned kb article. In one place it generates an assembly in the database called

CREATE ASSEMBLY [MyTest.XmlSerializers] from
'C:CLRTestMyTestMyTestinDebugMyTest.XmlSerializers.dll'
WITH permission_set = SAFE

and in another it uses

USE dbTest
GO
CREATE ASSEMBLY [MyTest] from 'C:CLRTestMyTest.dll'
GO
CREATE ASSEMBLY [MyTest.XmlSerializers.dll] from 'C:CLRTestMyTest.XmlSerializers.dll'
GO

I can't get either to work, and I've tried various combinations, this and the fact that the kb artice uses two different naming conventions suggests to me that there must be "something else" which links the assembly with the serialization assembly.

Any ideas?

Thanks,

Dan

Could Not Load File Or Assembly 'System.Data.SqlServerCe, Version 3.5.0.0

May 8, 2008

We just upgraded our applications from VS 2005 to VS 2008 and discovered we had to convert our SQL Server CE databases. So I did that. I then included the sqlce...35.dlls in the application directory on my test computer as well as the System.Data.SqlServerCe.dll version 3.5.

sqlceca35.dll
sqlcecompact35.dll
sqlceer35EN.dll
sqlceme35.dll
sqlceoledb35.dll
sqlceqp35.dll
sqlcese35.dll

When I run the app and it tries to load the System.Data.SqlServerCe.dll I get the following error:
System.IO.FileLoadException: Could not load file or assembly 'System.Data.SqlServerCe, Version 3.5.0.0...or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

We have the application targeting the .NET Framework 2.0 and need to keep it that way for awhile.

Any ideas on how to resolve the error?

If Server is Window 64 Bit
"C:Program FilesMicrosoft SQL Server100DTSBinn"

Tried Another Resolution:

If Server is Window 32 Bit
"C:Program Files (x86)Microsoft SQL Server100SDKAssemblies"
If Server is Window 64 Bit

Calling VB Based SQLCLR Function Failed With Error Can't Load System.Web Assembly

Apr 20, 2007

I created a CLR function based on following VB code:



Imports Microsoft.SqlServer.Server

Public Partial Class SqlClrVB

<Microsoft.SqlServer.Server.SqlFunction()> _

Public Shared Function GetTotalPhysicalMemory() As Integer

GetTotalPhysicalMemory = My.Computer.Info.TotalPhysicalMemory

End Function

End Class



The VB code was complied into a DLL called totalmem.dll and call following TSQL to map it into a SQL function:



create assembly totalmem from '!WORKINGDIR! otalmem.dll'

WITH PERMISSION_SET=UNSAFE

go

create function fnGetTotalMem()

returns int

as external name totalmem.SqlClrVB.GetTotalPhysicalMemory

go



When I call this function, it returned following error:

select dbo.fnGetTotalMem()



Msg 6522, Level 16, State 2, Line 0

A .NET Framework error occurred during execution of user defined routine or aggregate 'fnGetTotalMem':

System.IO.FileNotFoundException: Could not load file or assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

System.IO.FileNotFoundException:

at Microsoft.VisualBasic.MyServices.Internal.ContextValue`1.get_Value()

at My.MyProject.ThreadSafeObjectProvider`1.get_GetInstance()

at SqlClrVB.GetTotalPhysicalMemory()

.



Anyone knows why I'm hitting this error? I didn't reference any System.Web interface why it needs to load System.Web assembly? The same code runs OK if I compile it as a separate VB application out side of SQL Server 2005.



Thanks much,



Zhiqiang

ALTER ASSEMBLY Error Msg 6509 An Error Occurred While Gathering Metadata From Assembly ‘&&<Assembly Name&&>’ With HRESULT 0x1.

Feb 22, 2008

I work with February CTP of SqlServer 2008.
I have an Assembly with several UDTs inside. Version of assembly is 1.0.*
I use CREATE ASSEMBLY statement to register this assembly, and it runs without any errors. Then I rebuild CLR solution without doing any changes in source code. In that case the only difference between new and old assemblies is version (difference in fourth part of version).
Then I try to update assembly in SqlServer. I use
ALTER ASSEMBLY <name>
FROM <path>
WITH PERMISSION_SET = UNSAFE, UNCHECKED DATA
statement for this. Statement runs with error:
Msg 6509An error occurred while gathering metadata from assembly €˜<Assembly name>€™ with HRESULT 0x1.
I found the list of condition for ALTER ASSEMBLY in MSDN:
ALTER ASSEMBLY statement cannot be used to change the following:
· The signatures of CLR functions, aggregate functions, stored procedures, and triggers in an instance of SQL Server that reference the assembly. ALTER ASSEMBLY fails when SQL Server cannot rebind .NET Framework database objects in SQL Server with the new version of the assembly.
· The signatures of methods in the assembly that are called from other assemblies.
· The list of assemblies that depend on the assembly, as referenced in the DependentList property of the assembly.
· The indexability of a method, unless there are no indexes or persisted computed columns depending on that method, either directly or indirectly.
· The FillRow method name attribute for CLR table-valued functions.
· The Accumulate and Terminate method signature for user-defined aggregates.
· System assemblies.
· Assembly ownership. Use ALTER AUTHORIZATION (Transact-SQL) instead.
Additionally, for assemblies that implement user-defined types, ALTER ASSEMBLY can be used for making only the following changes:
· Modifying public methods of the user-defined type class, as long as signatures or attributes are not changed.
· Adding new public methods.
· Modifying private methods in any way.

But I haven€™t done any changes in source code, so new version of assembly satisfies all this conditions.
What could be the reason for such behavior?
P.S. I€™ve got the same error, if I add or change any method in assembly before rebuilding.

Msg 6573 Method, Property Or Field In Assembly Is Not Static. VB.Net Assembly In SQL Server Problem

Feb 29, 2008



I am trying to get a function I created in VB 5 for Access and Excel to work in SQL 2005. I was able to update the old VB code to work in VB 2005. I compiled and made a .dll, and I was able to register the new Assembly in SQL Server. When I try to create the Function, I get an error:


CREATE FUNCTION dbo.Temperature(@FluidName char, @InpCode Char, @Units Char, @Prop1 varchar, @Prop2 varChar)

RETURNS VarChar

AS EXTERNAL NAME FluidProps.[FluidProps.FluidProperties.Fluids].Temperature


Error returned:


Msg 6573, Level 16, State 1, Procedure Temperature, Line 21

Method, property or field 'Temperature' of class 'FluidProps.FluidProperties.Fluids' in assembly 'FluidProps' is not static.



Here is the code (part of it) in the VB class:

Header:


Imports Microsoft.SqlServer.Server

Imports System.Data.SqlClient

Imports System.Runtime.InteropServices

Imports System.Security

Imports System.Security.Permissions





Namespace FluidProperties



'Option Strict Off

'Option Explicit On

Public Partial Class Fluids

Function:


Function Temperature(ByRef FluidName As Object, ByRef InpCode As Object, ByRef Units As Object, ByRef Prop1 As Object, Optional ByRef Prop2 As Object = Nothing) As Object

Call CalcProp(FluidName, InpCode, Units, Prop1, Prop2)

Temperature = ConvertUnits("-T", Units, T, 0)

End Function


If I change the Function Temperature to Static, I get an error that functions cannot be Static. Its been a long time since I created the code and am having a hard time in my older age of getting the cobwebs out to make it work.

I have no problem getting the function to work if I call it from a VB form....so what do I need to do to get it to work on data in my SQL server?

Thanks

Creating A System.Management Assembly In Order For My Own Assembly To Work?

Aug 2, 2006

Hi

I am a bit paranoid about what I just did to my SQL Server 2005 with this CLR experiment.

I created a Class Lib in C# called inLineLib that has a class Queue which represents an object with an ID field.

in another separate namespace called inLineCLRsql, I created a class called test which will hold the function to be accessed from DB, I referenced and created an instances of the Queue class, and retrieve it's ID in a function called PrintMessage.

namespace inlineCLRsql{


public static class test{


public static void PrintMessage(){



inLineLib.Queue q = new inLineLib.Queue();

int i = q.queueId ;

Microsoft.SqlServer.Server.SqlContext.Pipe.Send(i.ToString());



}

}

}

to access this from the db, I attempted to create an assembley referencing inLineCLRsql.dll. This didn't work as it complained about inLineLib assembly not existing in the db. I then attempted to create an assembley for inLineLib but it barfed saying System.Management assembly not created.

so what I did is (and this is where I need to know if I just ruined sql server or not):

1- ALTER DATABASE myDB SET TRUSTWORTHY ON;.

2- CREATE ASSEMBLY SystemManagement

FROM 'C:WINDOWSMicrosoft.NETFrameworkv2.0.50727System.Management.dll'

WITH PERMISSION_SET = UNSAFE

3- CREATE ASSEMBLY inLineLibMaster

FROM 'D:inLineServerinLineLibinDebuginLineLib.dll'

WITH PERMISSION_SET = unsafe

4- and finally

CREATE ASSEMBLY inLineLib

FROM 'D:inLineServerCLRSQLinlineCLRsqlinDebuginlineCLRsql.dll'

WITH PERMISSION_SET = SAFE



Everything works after those steps (which took some trial and error). I can create a sproc like:

CREATE PROC sp_test AS

EXTERNAL NAME inLineLib.[inlineCLRsql.test].PrintMessage

and it returns the Queue ID

Is there anything unadvisable about the steps above?



Thanks for your help

Error Registering Assembly Using CREATE ASSEMBLY

May 1, 2008

We have written a test CRL stored procedure to test replacing one of our complex stored procedures but can€™t get it deployed to our SQL server that hosts a mirrored configuration of our production database (very locked down). It works fine on our development instances (not very locked down). It only references the default assemblies that were added when we created the project. All it does is use Context Connection=true to get data, loops though some records and returns the data using SQLContext. CLR is enabled on SQL server, the assembly is strongly signed, and we tried deploy using the binary string with the SAFE setting.


CREATE ASSEMBLY for assembly 'SQLCLRTest2' failed because assembly 'SQLCLRTest2' failed verification. Check if the referenced assemblies are up-to-date and trusted (for external_access or unsafe) to execute in the database. CLR Verifier error messages if any will follow this message
[ : SQLCLRTest2.StoredProcedures::GetLift][mdToken=0x600001e] Type load failed.
[token 0x02000008] Type load failed.

Custom Assembly SecurityException

Feb 26, 2008



Hi,

I'm trying to do something rather weird, but I really need it. I'm trying to launch a SSIS package from a report

I built a custom assembly with one method that loads a package from file and then executes it. The assembly works fine.

I added the custom assembly to the report properties, instantiated the class in the assembly (the method is not static), called the method from the report (a textbox renders the string return value from the method).

I added the


Code Snippet[assembly: System.Security.AllowPartiallyTrustedCallers]
attribute to the AssemblyInfo.cs file

Created the strong name for the assembly.

Got the PublicKeyBlob with ILDASM, used it to add a new CodeGroup with the "StrongNameMembershipCondition" in the policy configuration files of ReportDesigner (RSPreviewPolicy.config), ReportServer (rssrvpolicy.config) and ReportManager (rsmgrpolicy.config).

Copied the dll in the bin folders of ReportServer and Visual Studio PrivateAssemblies.


I keep getting the awfull #Error message on the report when viewing it from ReportManager or ReportServer (in preview mode in VisualStudio all is well because security is not applied to user code).


I tried debugging:
- created a solution with two subprojects, one is the report, the other one is the assembly
- marked the report as the Startup Item
I get a SecurityException in debug and debuglocal modes when I try to instantiate a SSIS package.



Code SnippetPackage = new Package();

While digging in the exception call stack, it turns out I lack a permission for accessing unmanaged code (the source assembly of the exception is mscorlib). Also in the ouput window, while starting debugging i see a lot of SystemArgument exceptions in mscorlib.

I am perfectly aware that in order to be able to launch a SSIS package from code I referenced Microsoft.SqlServer.DtsRuntimeWrap.dll, so in desperation I added another CodeGroup in the aforementioned config files for this dll (StrongNameMembershipCondition) and copied the assembly in the deployment folders.


1: I would really like to know how to get the whole thing working. I find rather strange that even though I set the FullTrust

PermissionSet for my assembly (and the Microsoft.SqlServer.DtsRuntimeWrap assembly) I keep getting security exceptions.

While exploring the web for help I saw I need to assert all individual permissions for every restricted resource I'm accessing in the custom assembly, problem is I don't know exactly which ones I'm accessing and, being new to .NET security, I don't know how.

Surely I need to assert a file IO permission to load the package from file, a sqlclientpermission if I am accessing SqlServer in the package, and perhaps a unmanagedcode permission, given the the exception I described earlier (perhaps the Microsoft.SqlServer.DtsRuntimeWrap assembly is not managed code or is accessing some other unmanaged assembly).

Again, I wouldn't know how.

...and last

2: I tried modifying the assembly to only load a string from a file.. I had some problems with security but I got it working once, but I haven't figured out how exactly 'cause when fiddling around to understand things, I lost the working configuration. Really stupid, I know....
While testing this version of the assembly I followed an advice I found on some blog and restarted IIS and Reporting Services system service..

Is this always necessary after modifying the assembly source ? Do I need to restart every time both IIS AND Reporting Services

I would really appreciate every bit of help or advice anyone has to offer.

Thanks in advance.

Using Custom Assembly &&amp; Gacutil &&amp; Sn

Jan 22, 2008

Hello experts,

I need some help please.
Yesterday I get the answer that I had to use an assembly if I would like to use a function as global. Right now I€™m very desperate because my VS didn€™t recognize my DLL.
I get the error: "Could not load file or assembly .....The system cannot find the file specified."
After red the threads I tried to use gacutil.exe to add my assembly to the cache.
This action fails with the error:€? Failure adding Assembly to cache. Attempt to install an assembly without a strong name.€?
After that I tried to build a strong name through the follow execute:
Sn €“Vr ClassLibrary.dll. This action fails too. I get the follow Error description: €œdll does not represent a strongly named assembly€?.

What made me wrong?
Is there an easier workaround?
Have someone a good Idea could help me?

Hope to hear you soon.

Best regards,
Alex
