Custom Log Provider Type Not Recognized As A Valid Log Provider

I am new to SSIS but I am learning fast. Any help is greatly appreciated.

I have written a custom log provider derived from LogProviderBase. I want to programmtically add the custom log provider to my package, but when I try this:

myPackage.LogProviders.Add("ACustomLogProvider");

I get the following exception:

"The log provider type "ACustomLogProvider" specified for log provider "{..GUID..}" is not recognized as a valid log provider type. This error occurs when an attempt is made to create a log provider for unknown log provider type. Verify the spelling in the log provider type name".

I have followed the instructions in BOL and as suggested in this forum, adding the DtsLogProvider attribute:

[DtsLogProvider(DisplayName="ACustomLogProvider", LogProviderType="ACustomLogProvider", Description="a description")]

Another way I tried is that I added a GUID attribute to my custom log provider class and then tried this:

Type aType = typeof(ACustomLogProvider);

Guid aGUID = (Guid)aType.GUID;

myPackage.LogProviders.Add("{"+ aGUID.ToString() +"}");

This also gives me the same exception "The log provider type ""{..the actual GUID for ACustomLogProvider..}" specified for log provider "{..a different GUID..}" is not recognized as a valid log provider type....

My questions are: Is it possible to add a custom log provider programmtically or must it be done through the SSIS Designer?

Must I deploy my custom log provider class for it to work programmatically? (I had perhaps wrongly assumed I would not have to deploy if I don't want it to show up in the SSIS Designer).

I would prefer to use a custom log provider instead of just logging within the SSIS event handlers because I can override the OnPostExecute, etc. but I cannot (can I?) override the specific event handlers like PackageStart, PackageEnd, etc because they are not exposed through DTSEvents.

Any help I would be very grateful for. Thanks.
