Running websites in 2.0 and 4.0 on same IIS

This sounds like a very difficult task but its really now.

Lets take it a scenario to make it happen .

I have a Widows 2008 server with IIS 6.1 installed on it . I have some applications running on it already which are built on .net2.0 framework.

I want to host new application built in .net 3.5 or 4.0 framework .


  1. Download the new framework from below link

2. install it .

3. Restart computer register the new framework on IIS server



5. Now you will get new framework application pool in your IIS


6. Assign this application to your application.


That’s it!!
