Dan Fernandez has resulted very interesting example of use That in C# 2.0.

As you know for this purpose in VB already there is keyword My.

Using "My", you can write code like this:

Dim contents As String
contents = My.Computer.FileSystem.ReadAllText("c:\mytextfile.txt")



Instead of this
 


Dim contents As String
contents = IO.File.ReadAllText("c:\mytextfile.txt")

Interesting trick allow every assembly run in its own memory space and own its own configuration.
