I am running .NET 2.0 / .NET 1.1 application side-by-side by I can no longer find the ASP.NET version tab setting for a web application, how do I change this?
You must update the script map for that specific web application.
First, go into the .NET framework folder that you wish to update to,
e.g. \Windows\Microsoft .NET\Framework\v1.1 and run " aspnet_regiis.exe
-s W3SVC/1/ROOT/MyApplication " where MyApplication is replaced by the
name of the virtual directory whose application you wise to update.
