I have an VB.net application where the supportedRuntime is mentioned as <supportedRuntime version="v4.0"/><supportedRuntime version="v2.0.50727"/> in config file. According to Microsoft Link on computer with version 4 or later versions installed application runs on 4 or later versions.

I have got Environment.Version that gives the CLR version but have a warning mentioned as "For the .NET Framework 4.5 and later, we do not recommend using the Version property to detect the version of the runtime" link

When I use Environment.Version I get "4.0.30319.42000". According to microsoft link suggests For .NET Framework 4.6 and later versions, it has the form 4.0.30319.42000.

Is there any way to know the exact version of the .NET Framework the application will target on runtime if multiple versions of .NET Framework 4 and above is installed.

Also RuntimeInformation.FrameworkDescription Property gets the name of the .NET installation on which an app is running but requires .NET Framework 4.7.1, 4.7.2, 4.8, 4.8.1.

So I want to know any other method that will work irrespective of the framework version.

  • It's not clear why you need this information or when you need it. The information can be found in each project's `.csproj` or `.vbproj` file - look at `TargetFrameworkVersion`. – Tu deschizi eu inchid Apr 01 '23 at 13:59
