.Net 4.0, New Methods in Existing Classes

Question

Is there a blog or MSDN article that lists all the new methods added in .Net 4.0 in existing classes? I could not find.

Two that I have found on blogs so far:

String.IsNullOrWhiteSpace Enum.HasFlag 

Are there any other methods that anyone has found? If yes, please share.

Answer 1

The .NET BCL library blog (base class library) has a list of changes, although for .NET 4 Beta 1 and 2:

Answer 2

There are several new pages in the class:

 Page.MetaDescription = ""; Page.MetaKeywords = ""; 

Plus new method 301:

 Response.RedirectPermanent("~/page.aspx"); 

I think that this is not the best way to approach it, since many of the new functions do not make much sense without being placed in context.

This document highlights most of the new features if you want to get speed on .net 4:
