Build regression from 5.0.6 to 5.0.7

[joshudson]

C:\Program Files\dotnet\sdk\5.0.301\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.targets(993,5): error NETSDK1150: The referenced project '..\Cedaron.Build.CreateAssemblyInfo\Cedaron.Build.CreateAssemblyInfo.csproj' is a non self-contained executable. A non self-contained executable cannot be referenced by a self-contained executable. [src\Cedaron.FormBuilder.Migrate\Cedaron.FormBuilder.Migrate.csproj]

Only happens when building with a rid rather than a rid-independent build

This error doesn't stop the build but returns a nonzero error code from dotnet.exe causing the build chain to fail.

Relevant lines from Cedaron.Build.CreateAssemblyInfo.csproj:

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

  <PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>
    <RuntimeFrameworkVersion>5.0.7</RuntimeFrameworkVersion>
    <LangVersion>9.0</LangVersion>
    <OutputType>Exe</OutputType>
  </PropertyGroup>
  <Target Name="PostcompileScript" AfterTargets="Build">
    <Exec Command="dotnet $(OutputPath)/$(AssemblyName).dll" />
  </Target>

</Project>

Relevant lines from Cedaron.FormBuilder.Migrate.csproj:

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

  <PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>
    <RuntimeFrameworkVersion>5.0.7</RuntimeFrameworkVersion>
    <LangVersion>9.0</LangVersion>
    <DebugType>portable</DebugType>
    <OutputType>Exe</OutputType>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
  </PropertyGroup>

  <ItemGroup>
    <Compile Include="../AssemblyInfo.cs" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Cedaron.Common.Loader" Version="1.0.0" />
    <PackageReference Include="Newtonsoft.Json" Version="11.0.2" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Cedaron.Common" Version="2.2.0" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\Cedaron.Build.CreateAssemblyInfo\Cedaron.Build.CreateAssemblyInfo.csproj" Properties="RuntimeIdentifier=">
      <ReferenceOutputAssembly>false</ReferenceOutputAssembly>
      <Private>false</Private>
    </ProjectReference>
  </ItemGroup>

So what is this? The ProjectReference is needed because Cedaron.Build.CreateAssemblyInfo.csproj is a dependent project project, but the actual output of Cedaron.Build.CreateAssemblyInfo.csproj is AssemblyInfo.cs; the fact that it produces an executable is a byproduct.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Minimized. builds with dotnet build; doesn't build with dotnet build -r win7-x64

See this notice for the workaround and why this was introduced: https://docs.microsoft.com/en-us/dotnet/core/compatibility/sdk/5.0/referencing-executable-generates-error

Ah that link contains the unfortunate text "neither would launch" and neither is CreateAssemblyInfo copied to the output directory so I thought it was talking about something else.
