As I mentioned earlier, there is no project file to remove a reference from. In Visual Studio 2008 there are 2 types of web projects, one that uses a project file and 1 that does not. The type that does not uses the bin directory to determine which files to reference. This is the type I am using.

 

The file that I have in the bin directory is the version 6.1 DLL. I have deleted the 5 files that are causing the compile errors and everything works fine, but I would like to resolve this by not having to delete the files.

 

What do I need to do?
