Changing .Net framework
By default accounts on both our Windows 2008 / IIS 7 servers and Windows 2012 / IIS 8 servers are set up to use ASP.NET
framework 2.0 with ASP.NET 3.0 and 3.5 extensions enabled as this is the most commonly used version.
However framework 4.0 is also installed alongside ( plus 1.1 on Windows 2003 / IIS 6 servers ) and we are able to switch between the different frameworks on a per site basis.
If you would like to change the framework set on your hosting account please contact support requesting the change and be sure to include
in your ticket the name of the domain to be switched.
