Automatically rebuild referenced Class Libraries (DLLs) in VS2010?

I have an executable project A, which references to a Class Lib开发者_JAVA百科rary project B. However, when I build A, it does not automatically rebuild B. The only way to get B rebuilt and used by A is to rebuild B then build A.

Is there a way I can get B to be rebuilt automatically and then used by A when I build A?

Check B in your solution configuration.
