visual-studio-2010 - Visual Studio 2010 C++ Project: Build Release EXE File generates EXE, LIB and EXP File. Why?

Question

I'm building a C++ project in Release-Mode and the target type is an EXE-File. The project also generates a .lib and a .exp-file. What is wrong? I only want to build an exe-file.

Any ideas?

Thank you very much!!!
