Windows lies to dotnet.exe abouts the OS version

See original GitHub issue

Steps to reproduce

On Windows 10:

mkdir test
cd test
dotnet new console
Change Program.cs to call Console.WriteLine(Environment.OSVersion.Version)
dotnet run

Expected behavior

See “10.0.17663” (for example, on RS5)

Actual behavior

See “6.2.9200.0”

This is because dotnet.exe’s RT_MANIFEST resource is auto-generated with only the asInvoker privilege level, but is lacking the supportedOS. Instead, you should consider authoring a manifest like the following and adding it to your dotnet.csproj as the ApplicationManifest:

<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'>
    <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
        <security>
            <requestedPrivileges>
                <requestedExecutionLevel level='asInvoker' uiAccess='false' />
            </requestedPrivileges>
        </security>
    </trustInfo>
    <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
        <application>
            <supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}" />
            <supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}" />
            <supportedOS Id="{4a2f28e3-53b9-4441-ba9c-d69d4a4a6e38}" />
            <supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}" />
            <supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}" />
        </application>
    </compatibility>
</assembly>

This is problematic when running dotnet run with a console app that needs the correct Windows OS version, such as a benchmark application using BenchmarkDotNet.

Hi @heaths,

It’s a tad bit confusing, but this repo is responsible for building dotnet.dll which implements the .NET Core SDK; technically the “CLI” interface, whereas the dotnet/sdk repo implements the MSBuild-side of the SDK. As you’ve already discovered, dotnet.exe (the native “muxer” responsible for finding and loading .NET Core SDKs) is actually built out of dotnet/core-setup and the issue you’ve linked to has been fixed for the current 3.0 preview SDK.

Would you mind trying this with the x64 3.0 preview SDK and see if the issue has been adequately resolved?

Thanks!

p.s. I remember you from the DevHood days, some 18 years ago, crazily enough!
