Where can I find the Xml Documentation files for the .NET 4.0 or 4.5 framework?

Question

for .NET 2.0, the xml documentation files for the framework assemblies where located at this position:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\en

I can't find a corresponding folder for .NET 3.5, 4 or even 4.5.

So, where, by default, are the xml documentation files for the framework assemblies located for newer .NET framework versions?

I'm especially interested in System.Web.dll documentation.

c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework
