- Plesk for Windows
Does Plesk support ASP.NET 4.x?
ASP.NET 4.x is supported by Plesk 11, 12 and Onyx.
All ASP.NET versions starting 1.1 up to 4.x are supported by Plesk from version 11 up to Plesk Onyx.
Note: (1) As .NET 4.x Framework is an iterative update of .NET 4.0, IIS will continue displaying available version of ASP.NET as 4.0, and Plesk will display the updated version.
Note: (2) See KB article #213392489 for instructions on how to set up .NET 1.1 Framework on Windows 2008 with IIS7.
