Windows version / .NET Framework

Question

Hello,

I want to know which Windows version is installed and which .NET Framework version.
How and with which function can I read it?
My system Win10, VS2019.

Answer 1

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:

So, you could use VS to create a .net framework project.

Best regards,

Elya

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.
