Upgrading to ASP.Net Core 2.1 added a new recommendation for using Docker as a development environment, which is to add a Directory.Build.props file that will specify where to put the BaseIntermediateOutputPath and BaseOutputPath depending on the executing environment.

With the Directory.Build.props in place everything works as expected except dotnet ef commands. I'm running dotnet ef migrations list -s ./Y/ -p ./X/ The error generated is,

X/X.csproj : error MSB4057: The target "GetEFProjectMetadata" does not exist in the project.
Unable to retrieve project metadata. Ensure it's an MSBuild-based .NET Core project. If you're using custom BaseIntermediateOutputPath or MSBuildProjectExtensionsPath values, Use the --msbuildprojectextensionspath option.

By following the error's recommendation and adding the --msbuildprojectextensionspath option with the value obj/local, i.e. dotnet ef migrations list -s ./Y/ -p ./X/ --msbuildprojectextensionspath ./X/obj/local, the error reoccurs though now it's requesting that the other project in question's --msbuildprojectextensionspath be given. Error meesage

Y/Y.csproj : error MSB4057: The target "GetEFProjectMetadata" does not exist in the project.
Unable to retrieve project metadata. Ensure it's an MSBuild-based .NET Core project. If you're using custom BaseIntermediateOutputPath or MSBuildProjectExtensionsPath values, Use the --msbuildprojectextensionspath option.

Running this now with dotnet ef migrations list -s ./Y/ -p ./X/ --msbuildprojectextensionspath ./Y/obj/local everything works as expected.

Directory.Build.props contents are,

<Project>

  <PropertyGroup>
    <DefaultItemExcludes>$(DefaultItemExcludes);$(MSBuildProjectDirectory)/obj/**/*</DefaultItemExcludes>
    <DefaultItemExcludes>$(DefaultItemExcludes);$(MSBuildProjectDirectory)/bin/**/*</DefaultItemExcludes>
  </PropertyGroup>

  <PropertyGroup Condition="'$(DOTNET_RUNNING_IN_CONTAINER)' == 'true'">
    <BaseIntermediateOutputPath>$(MSBuildProjectDirectory)/obj/container/</BaseIntermediateOutputPath>
    <BaseOutputPath>$(MSBuildProjectDirectory)/bin/container/</BaseOutputPath>
  </PropertyGroup>

  <PropertyGroup Condition="'$(DOTNET_RUNNING_IN_CONTAINER)' != 'true'">
    <BaseIntermediateOutputPath>$(MSBuildProjectDirectory)/obj/local/</BaseIntermediateOutputPath>
    <BaseOutputPath>$(MSBuildProjectDirectory)/bin/local/</BaseOutputPath>
  </PropertyGroup>

</Project>

The directory structure of the project is,

/
  Directory.Build.props
  src/
     X/
        X.csproj
     Y/
        Y.csproj

I'm running this in the local environment and all commands were run form the src directory.

This looks similar to #8816, though I'm not sure how to get this work with Directory.Build.props. Can you please assist in providing a solution to this issue?
