Cannot Connect To MSDE From C# Code

Hello everybody and happy holidays to all.


I'm new to C#, and I appologize for this basic question.


I am trying to connect to an SQL database from a very short C# program, which I found on the Microsoft site, demonstrating this subject.


Here is my setup:


Windows 2000 Professional


dotNET Framework 1.1 with sp1 installed


MSDE 2000


Note: I do not own nor do I have Visual Studio.NET of any kind installed.





Now, here is what works:


osql -E -S localhostvsdotnet


1>


And I can create and populate a database, which I called mydb.





Now, in my simple C# demo program I have this line





SqlConnection mycon = new SqlConnection("server=localhost;database=mydb;trusted_connection=true");





And the program compiles OK using "csc" command. But when I run it, I get this message:


Couldn't Open Connection to server=localhost;database=mydb;trusted_connection=true





Could anybody comment on what am I missing?


Thanks.
