- Create a new application pool:
Right click on Application Pools and go to New > Application Pool.
Name it "DotNet2" or something like that, and click OK. You will see it added to your list of application pools.
- Tell your application to use the appropriate application pool:
Right click on your application and go to Properties. Switch to the Home Directory tab. At the bottom should be your Application Name. If this section is disabled then click the button to create a new application. Give it an easily identifiable name. The box at the very bottom will allow you to choose your application pool. Select DotNet2, or whatever you had named it in step 1.
- Tell IIS to use ASP.NET 2.0:
Switch to the ASP.NET Tab. For the version use the drop down box to select 2.0.xxx.
That's it! You can leave your 1.1 applications running in the DefaultAppPool and they will be fine.
