OSVersion

In windows 8.1 Environment.OSVersion underlying Win32 GetVersionEx function changed to for compatibility reasons report latest version app is compiled for.

The code

Console.WriteLine(
    System.Environment.OSVersion
    );
  • Without 8.1 ID on 8.1
    • Microsoft Windows NT 6.2.9200.0
  • Without 10 ID on 10
    • Microsoft Windows NT 6.3.9600.0
  • With 10 ID on 10
    • Microsoft Windows NT 10.0.10049.0

Usage

If you have an app.manifest just add the <supportedOS Id/> you are missing. Otherwise just Add new item to the project, search for manifest and choose Application Manifest File with file name app.manifest

Basically your .csproj should include (should just work if you add an Application Manifest File with file name app.manifest)

  <PropertyGroup>
    <ApplicationManifest>app.manifest</ApplicationManifest>
  </PropertyGroup>

and

  <ItemGroup>
    <None Include="app.manifest" />
  </ItemGroup>

  1. see that your xml is properly formatted source.

  2. not having supportedOS will run your app in vista virtualization mode.

    my application is still recognising Win10 as Win6
    it might be helpful to query for the actual version using API/WMI:

Thanks.
Sorted; I ran it again a day or two later and it worked properly.
