I have a dll that I use in several projects, that I placed in the Global
Assembly Cache. This dll is references in each of my projects.

This Dll is referenced by a type= declaration in my web.config as follows.

The issue I am having is that since this dll is in the GAC, ASP.NET doesn't
know where the actuall DLL file is. I get an exception when ASP .NET is
trying to do a Type.GetType on
Microsoft.ApplicationBlocks.ExceptionManagement.

This is because it's trying to locate the
Microsoft.ApplicationBlocks.ExceptionManagement.dll in several places (as
you can see in the Exception below).

ASP .NET won't find the Microsoft.ApplicationBlocks.ExceptionManagement.dll
because it's in the GAC, not in any of the places it's looking for.

If I change the Copy Local property of the reference to True, this is a non
issue. This is because the
Microsoft.ApplicationBlocks.ExceptionManagement.dll is copied to the bin
directory of the website.

But isn't the whole point of the GAC that I don't have to have a copy of a
dll (that's in the GAC) in every application's bin directory?
