What are the signatures of the various versions RRS feed

  • Question

  • I have a PC with .NET 3.5 only.  I ran a Windows Forms application and AppDomain.CurrentDomain.GetAssemblies() gives me the following (my own assembly removed):

      mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089
      System.Windows.Forms, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089
      System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089
      System.Drawing, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
      System.Configuration, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
      System.Xml, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089
      System.Deployment, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a

    Why are the versions of the assemblies still

  • Hi K.Kong,

    .NET Framework 3.5 includes .NET Framework 2.0 and 3.0. They are the prerequisite of .NET Framework 3.5.

    The .NET Framework has two main components: the common language runtime (CLR) and the .NET Framework class library. The common language runtime is the foundation of the .NET Framework. .NET Framework 3.5 uses CLR version 2.0 and so does .NET Framework 2.0 or 3.0, while .NET framework 1.1 uses v1.1.
    The Core parts are referred to speak as the 'Red Bits' and the rest as the 'Green Bits'.
    For more information, see:

    The assemblies that you listed above like 'mscorlib' are the core assemblies of .NET Framework. Thus, the assemblies are still

    Hope this helps. If you have any concern, please feel free to let me know.

    Best regards,
    Yichun Chen
