Select ASP.NET Version in IIS 7

IIS7_Select_ASPNET_Version

In IIS 7, ASP.NET version selection is different from that on the earlier versions of IIS.  In this version, the ASP.NET version is specified in an application pool.  You can create a new application pool and let your Web application use it (see picture on the left).

Using a separated application pool also gives you a better performance - in exchange of resources though.
