Problem in IIS while hosting?

Hi sir,
I have developed one web application with framework 4.0. I have installed framework 2.0 and 4.0 in my system. If i hosted that web application in IIS, it will not work due to "Server Application Unavailable" error. I want to view both the framework 2.0 and framework 4.0 websites in IIS.

[Hint: If i hosted framework 2.0 in IIS, i cant able to view the framework 4.0 websites. I want to view both the frameworks website]

Kindly give me the solution for this problem.

With regards,

Hello Prabu_Spark,

I believe this is not possible because Application pools cannot respond to two process at the same time and that is why you are getting the above error.

You will have to create different app pools for different framework.
You cannot assign both 2.0 and 4.0 to one process.
