问题
I have a web application which references an external DLL (lets call this productA.dll)
I have updated my GAC, my web.config, and my references, checked the versions and everything looks consistent.
However, when I run my application, methods that I use from productA.dll cannot be called, and I get a the specified module cannot be found error.
I tried creating a windows application and I can use productA.dll perfectly fine.
Observing the output window during run-time for the web application, I noticed that productA.dll symbols are not loaded. So I'm guessing that is why the module cannot be found.
The question is: why are the symbols not being loaded?
Any tips on the solution or diagnostics techniques would be greatly appreciated.

It's not a requirement that the assembly be in the GAC. I'd say to check the following:
- Your assembly is in the website's bin folder.
- Your assembly is referenced in the assemblies section of the web.config.
- The assembly reference in the web.config has the correct version number.
By the way, symbols will only be loaded if you have the debug file (.pdb) along side the assembly.
