Environment.Version Property


Gets a version consisting of the major, minor, build, and revision numbers of the common language runtime.

 static property Version ^ Version { Version ^ get(); };
public static Version Version { get; }
member this.Version : Version
Public Shared ReadOnly Property Version As Version

Property Value


The version of the common language runtime.


The following example displays the version of the common language runtime.

// Sample for the Environment::Version property
using namespace System;
int main()
   Console::WriteLine( "Version: {0}", Environment::Version );

This example produces the following results:
(Any result that is lengthy, specific to the machine on which this sample was tested, or reveals information that should remain secure, has been omitted and marked S"!---OMITTED---!".)

Version: !---OMITTED---!
// Sample for the Environment.Version property
using System;

class Sample
    public static void Main()
    Console.WriteLine("Version: {0}", Environment.Version.ToString());
' Sample for the Environment.Version property
Class Sample
   Public Shared Sub Main()
      Console.WriteLine("Version: {0}", Environment.Version.ToString())
   End Sub
End Class


For .NET Core 3.x and .NET 5+, the Environment.Version property returns the .NET runtime version number.

For the .NET Framework Versions 4, 4.5, 4.5.1, and 4.5.2, the Environment.Version property returns a Version object whose string representation has the form 4.0.30319.xxxxx. For the .NET Framework 4.6 and later versions, and .NET Core versions before 3.0, it has the form 4.0.30319.42000.


For the .NET Framework 4.5 and later, we do not recommend using the Version property to detect the version of the runtime; instead, you can determine the version of the common language runtime by querying the registry. For more information, see How to: Determine Which .NET Framework Versions Are Installed.

For more information about the version of the common language runtime that is installed with each version of the .NET Framework, see Versions and Dependencies.
