问题
I have a main executable project and a dll project in VS 2008.
Sometimes when I clean/rebuild the dll and then clean/rebuild the main project, the main project will not build because it says the dll is in use.
Closing both projects resolves the issue.
Why does this occur and how do I prevent it from happening? It is annoying having to close and reopen the projects.
Error received when building main project after building dll:
Unable to load referenced library 'C:\Documents and Settings\xxxxxx\Desktop\abcdefg\x64\Release\abdcefg.dll': The process cannot access the file because it is being used by another process.
