    Hi Markus Freitag,

    Regarding how to install .net framework on Win10, I recommend you refer to this document.

    Since you have already installed VS2019, you could also install it in visual studio installers:

    To know which version of .NET Framework is installed in your OS, read this: .NET Framework versions and dependencies

    If you want to read it programmatically, you will have to read the Registry Key (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full) as mentioned here:
    How to: Determine which .NET Framework versions are installed

    To determine which .NET implementation and version an app is running on, use RuntimeInformation.FrameworkDescription property.
