VS2005: Assembly '' is incorrect

Question

I've added a reference to the log4net assembly dll to my project.

When I build I get a warning saying:

Warning Assembly 'Lib\log4net.dll' is incorrectly specified as a file.

I look up the help for this error on MSDN, and it says:

This warning is generated during application manifest generation when the build process detects that a file reference is actually a (managed or native) assembly.

This is exactly what I'm doing; the file reference is an assembly. What am I being told here?

How do I add a reference to an assembly dll, while not adding a reference to an assembly dll?

Answer 1

Try setting the Build Action property of the source DLLs to None. It solved the issue for us.

Answer 2

I was running into this problem myself.

This is what worked for me:

I had added an assembly as a reference and as an "Existing Resource." Deleting the file from the Solution Explorer, closing, then reopening the project worked.
