My project references 3 different versions of mscorlib.dll

Question

I noticed that one of my projects refers to 3 different versions of mscorlib:

• 1.0.5000.0
• 2.0.0.0
• 4.0.0.0

This post about "mscorlib.dll and System.dll " helped me understand what mscorlib is for, but I wonder if this is normal / necessary for the application to require several versions of this assembly. Perhaps this happened because I updated my project from VS 2005 to VS 2010.

Is it possible for my project to refer only to version 4.0.0.0 mscorlib?

Answer 1

There are many reasons why you can do this. If you want only v4.0, make sure that you

• VS 2010
• ( Oracle), , .Net v4.0 dlls

, mscorlib. , v 4.0
