.NET framework support differs depending on whether your account is on a Windows 2003/IIS 6 or Windows 2008/IIS 7 server. You can find your web server type on the
Account Information page of Control Panel.
To view or change your .NET framework version in Control Panel, go to Tools & Utilities > IIS Tools > ASP.NET Version
Windows 2003/IIS 6 will have the following options:
1.1
2.0 or higher*
Windows 2008/IIS 7 will have the following options:
2.0 to 3.5
4.0
*Note that for Windows 2003/IIS 6, "2.0 or higher" includes 3.5, 3.0 and 2.0.
If you wish to take advantage of .NET 4.0 but your account is on a Windows 2003/IIS 6 server, you must migrate your account to a Windows 2008/IIS 7 server.
Migration
includes moving your files, updating DNS, etc., but any configuration
(directories set as application root, etc.) will not carry over, so
you
should
assume that some adjustments will have to be made post-migration.
Most ASP applications should work on both IIS 6 and IIS 7. But it is
important to note that some ASP.NET applications may require
modifications before they will work properly on IIS 7.
If you
have NOT tested your current site in Windows 2008/IIS 7 we do not
recommend migration until you have had a chance to test the effects of
the migration.
If you wish to proceed, please
visit this Control Panel page to
begin the migration.
