4. quick memory:

. NET 2.0 = CLR + Bcl + C # (VB. NET) + win form + web form.

. Net 3.0 =. NET 2.0 + WCF + WPF + WF + WCS

. Net 3.5 =. Net 3.0 + ASP. NET Ajax + Silverlight + LINQ + ADO. NET Entity Framework and data services

. Net 4.0 =. Net 3.5 + Plinq and task parallel + DLR + background GC

. Net 4.5 =. Net 4.0 +. Net for Metro + async + background JIT + Web sockets

6.Check the CLR version:

   System.Runtime.InteropServices.RuntimeEnvironment.GetSystemVersion()

7.Note:

• . NET Framework 1.0, 1.1, 2.0, and 4.0 are completely independent of each other.
• When versions 1.0, 1.1, 2.0, and 4.0 are on the same computer, each version has its own public Language Runtime Library, class library, and compiler,
• . NET Framework provides high backward compatibility support. Only for Version 1.1,. NET Framework also supports forward compatibility.
• Applications created with version 2.0 will not run in earlier versions of. NET Framework.

8. C # Language specifications:

Microsoft specifications

• Archives of old editions:
  • Third Edition (Jun 2005; PDF)
  • Second Edition (December 2002; PDF)
  • First edition (December 2001; PDF)

Annotated specifications

Both the ECMA and Microsoft teams have produced annotated specifications, with interesting comments from the design team and some members of the community. I can thoroughly recommend them as providing extra insight. (disclaations: I contributed annotations to the ECMA C #2 and Microsoft C #4 specs .)

• Microsoft (C #4) (due out in Fig 2010)
• Microsoft (C #3)
• ECMA (C #2)
