virtual directories with different .net frameworks

Question

Is it possible to have two virtual directories under the same website in IIS but have the virtual directories be using different versions of the .net framework?

Answer 1

You have to create an "application" for both of the virtual directories, and then you'd assign their ASP.NET version using the ASP.NET tab under web site properties.

Also, as @sunny mentioned, you'd need to have two different application pools, and each virtual directory would have to be pointed to a different application pool. Because different versions of ASP.NET cannot run within the same application pool.
