ASP.NET 2.0 is not available in the Hosting Settings for domains in Parallels Plesk. Only ASP.NET 4.0 is available.
How can ASP.NET 2.0/3.5 be enabled?
In Windows 2012 and 2012 R2, ASP.NET 2.0 and 3.0 are included in .NET 3.5. In order to enable this ASP version in the domains' Hosting Settings, follow steps below:
Open the Add Roles and Features Wizard and Server Role > Web Server (IIS) > Web Server > Application Development > ASP.NET 3.5.
- Go to Parallels Plesk > Tools & Settings > Server Components > and click Refresh to detect ASP.NET 3.5. Verify that ASP.NET 3.5 is shown in Hosting Settings.
Details on ASP.NET versions supported by Plesk are available in the Parallels Knowledgebase article #115337.
