- Plesk for Windows
What Plesk versions support ASP.NET 4.x?
ASP.NET 4.x is supported by Plesk 11, 12 and Onyx.
All ASP.NET versions starting from 1.1 up to 4.x are supported by Plesk from version 11 up to Plesk Onyx.
Note: 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 be displaying the updated version.
Note: Information about configuring .NET 1.1 Framework on Windows 2008 with IIS7 can be found in this article.
