web form code

Question

I am using Telerik JustDecompile to obtain the source code of the application. I want to make certain the C# 2010 web form source code matches what is really in production.

I am getting the Telerik JustDecompile to work correctly for app2.dll that is in the bin directory of the installed application.

However when I point Telerik JustDecompile to the app1.dll in the bin directory of the installed application, I really get the code for app2.dll. (Note: app1.dll is the main 'project folder' for the application.)

I do want to mention that if I point Telerik JustDecompile to the code that I want to compare against in the followibng directory path, C:orig_code\app1\obj\Release for app1.dll, I obtain the code I want to see.

Do you think I need to obtain the applicable app1.dll from the gac where the application is installed? If so, can you tell me where the gac is?

Thus can you tell me where I need to Telerik JustDecompile for app1.dll so that it will decompile the installed code for me?
