Global.asax.cs file is not recompiling--file is valid

Question

I recently refactored some code, and a method the original Global.asax.cs file was depending on was no longer static. When I made changes to my Global.asax.cs code to fix the compilation problem, VisualStudio Development Server is still reporting the old problem. To make things more confusing, it's reporting the old problem with the new source code.

When I start up the development server I get the tell-tale error screen saying:

Method not found: 'System.Security.Principal.IPrincipal Example.Records.AuthenticationManager.GetPrincipleForUserName(System.String);

This original exception was located at line 54--which shouldn't matter to you, me or anyone else. However, it matters to Development Server. No matter what I change the code to, even completely commenting out the original code, I get the same error message. The only difference is the snippet of code it displays. It's currently pointing to a comment line.

So DevelopmentServer is seeing the old compiled code and VisualStudio is seeing the new code. I can't set the breakpoint because VisualStudio is telling me the source code is different from the original version.

How can I force DevelopmentServer to see the new code that works?

Answer 1

The only thing I could do to make it work was create a new project and copy all my code in. It's not a good answer, but its the best I could come up with. Same exact code ran like a champ. After going through the project file line by line, I could not find anything that would explain the behavior I was seeing.
