`ApplicationManifest` is not respected when building for Windows on Linux

Describe the bug

We want to create a Windows .EXE from our application, in our Linux build chain. We can sucessfully create and run the exectuable on windows, but it comes without the manifest we put in the ApplicationManifest property in our csproj file.

When building on Windows, the manifest is embedded correctly.

To Reproduce

Create a manifest file to embed, like MyApp.manifest:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <assemblyIdentity type="win32" version="1.0.0.0" name="MyApp" />
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
        <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
      </requestedPrivileges>
    </security>
  </trustInfo>
  <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
    <application>
      <!--Windows Vista -->
      <supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}"/>
      <!--Windows 7 -->
      <supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}"/>
      <!--Windows 8 -->
      <supportedOS Id="{4a2f28e3-53b9-4441-ba9c-d69d4a4a6e38}"/>
      <!--Windows 8.1 -->
      <supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}"/>
      <!--Windows 10 -->
      <supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}"/>
    </application>
  </compatibility>
</asmv1:assembly>

In a new console app, add the ApplicationManifest to a PropertyGroup:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
  </PropertyGroup>

  <PropertyGroup>
    <ApplicationManifest>MyApp.manifest</ApplicationManifest>
  </PropertyGroup>

   ....
</Project>

Build it on Windows:

dotnet build -r win-x64 --self-contained -o Build

# Observe that the Exe file in Build has a manifest (a Shield in Windows Explorer to indicate it requires admin)

Build it in Linux (f.ex. the Dotnet 6 SDK docker images):

# Startup a docker container with SDK 6
docker run -it --rm -v $pwd`:/app mcr.microsoft.com/dotnet/sdk:6.0

# Build within Docker
cd /app
dotnet build -r win-x64 --self-contained -o Build

# Back in Windows, observe that the Exe file in Build is lacking a manifest

Exceptions (if any)

N/A

Is it planned for any future release? To be clear, this is a console app rather than GUI (which of course would have to be built on windows) and since we’re building all the other parts of this solution on linux it would be much simpler if we didn’t need windows just to embed the manifest into the final exe.

Just to be clear, there is no real reason why we couldn’t build Windows GUI apps on linux. It’s just the manifest that is broken, even for GUI apps.

Definitely something we would like to implement, it just hasn’t yet raised in priority enough to beat out a variety of other bug fixes and features. We would accept a community PR if someone wants to offer one.
