It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process.


Problem :- 
It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process.

Solution :-



This Error Cause Because of your Diffrent Asp.Net  framework running on a same Application pool.
to resolve this error assign diffrent application pool to diffrent framework.
In past i uploaded my Site on Server with IIS 6.0 Version.there are around 15 application running on Framework 1.1.I have uploaded my Framework 2.0 application And I found that 1.1 framework application goes Down.then i show in Event viewer it's dispaly that "It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process"
Then i have create seperate application pool for my asp.net 2.0 application and All Issues are resolved.
  Enjoy !!!!!!!!!!!!

  3. hi,
    nice solution.
    but there's still a problem, when server restarts it will set back to default value (eg. default pool with .net 1.1) which supposedly set to .net 2.0 framework.

    Do you have fixed setting for that one?

    Thanks.

  5. Hi,
    I'm not interested in asp.net 1.1.
    All I want is to ensure that my application is in right set of application pool everytime the server will restarts. Because the scenario is this, in my server I have two application pools (defaultappPool and AppPool#1) when my application is set to defaultAppPool it will cause an error "Server application unavailable" or "It is not possible to run two different versions of ASP.NET in the same IIS process. ". But when it sets to AppPool#1 there's no error. Now everytime my server restarts it will set to defaultAppPool which cause to error.

    Hope you got my point.
    thanks for the reply by the way.

  6. Additionally I have already .net 1.1 and .net 2.0 installed in the server. defaultPool was set to .net 1.1 and AppPool#1 was set to .net 2.0.
