-Thought I'd wanna share...-
I encountered this problem when I had to develop new parts of my website in ASP.NET 4.0. Boss wants it as a sub-virtual directory .
My development machine runs on WindowsXP, in which its IIS version cannot support multiple application pools like in IIS6. By "default", if I create a sub-virtual directory of different asp.net version, I will get "Application unavailable error". I thought
there's no fix except to upgrade to Win2003.
But I found a "solution". Here goes
In the main virtual directory (ASP.NET 2.0) I set the application protection to Medium(pooled)
In the sub-virtual directory (ASP.NET 4.0) I set the application protection to High(Isolated)
Now both works ! (http://blog.ediot.net/2010/05/iis51-different-aspnet-version-in-sub.html)
