SelfContained projects need to set Runtime Identifier after .Net upgrade from 7.0.103 -> 7.0.200

[paulkram]

Describe the bug

After updating my .Net SDK from 7.0.103 to 7.0.200 it complains:

Error NETSDK1191 A runtime identifier for the property 'SelfContained' couldn't be inferred. Specify a rid explicitly. C:\Program Files\dotnet\sdk\7.0.200\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.RuntimeIdentifierInference.targets 190

I also verified it working with 7.0.102 and broken with 7.0.201.

We have a list of RuntimeIdentifiers set in the project, that's not sufficient!

To Reproduce

Example project file:

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

  <PropertyGroup>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <LangVersion>latest</LangVersion>
    <IsPackable>false</IsPackable>
    <IsPublishable>false</IsPublishable>
    <StartupObject></StartupObject>
    <Platforms>AnyCPU</Platforms>
    <SelfContained>true</SelfContained>
    <RuntimeIdentifiers>win-x64;win-x86;osx-x64;osx.11.0-arm64;osx.12-arm64</RuntimeIdentifiers>
    <OutputType>WinExe</OutputType>
  </PropertyGroup>

  <ItemGroup>
    <Compile Remove="Helpers\**" />
    <Compile Remove="UnitTests\**" />
    <EmbeddedResource Remove="Helpers\**" />
    <EmbeddedResource Remove="UnitTests\**" />
    <None Remove="Helpers\**" />
    <None Remove="UnitTests\**" />
  </ItemGroup>

  <ItemGroup>
	<PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.4.1" />
	<PackageReference Include="Moq" Version="4.18.4" />
	<PackageReference Include="MSTest.TestAdapter" Version="3.0.2" />
	<PackageReference Include="MSTest.TestFramework" Version="3.0.2" />
	<PackageReference Include="RichardSzalay.MockHttp" Version="6.0.0" />
  </ItemGroup>

  <ItemGroup>
    <Folder Include="Properties\" />
  </ItemGroup>

</Project>

When setting

...
  <PropertyGroup>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <LangVersion>latest</LangVersion>
    <IsPackable>false</IsPackable>
    <IsPublishable>false</IsPublishable>
    <StartupObject></StartupObject>
    <Platforms>AnyCPU</Platforms>
    <SelfContained>true</SelfContained>
    <RuntimeIdentifiers>win-x64;win-x86;osx-x64;osx.11.0-arm64;osx.12-arm64</RuntimeIdentifiers>
    **<RuntimeIdentifier>win-x64</RuntimeIdentifier>**
    <OutputType>WinExe</OutputType>
  </PropertyGroup>
...

it works. Unfortunately then other steps like

<ItemGroup>
    <None Update="SomeFolder\**">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
  </ItemGroup>

fail, because it's not copying to

bin\yourproject\buildconfig\net7.0

but to

bin\yourproject\buildconfig\net7.0\<<runtimeidentifier>>\

Then tests from MSTest ran in the normal bin\yourproject\buildconfig\net7.0 path and everything breaks.

Exceptions (if any)

• none
