Running MS Fakes before build properly while using the new NetSDK project format

I am trying to get Microsoft Fakes to work properly with my unit test project (net47) wherein my project file format is using the new NetSDK format.

With Visual Studio 2019, I can add a Fakes Assembly and things seem to work fine, until we try to build/run the tests on our build agent. It seems as though when you compile/build a project the fakes assemblies are generated, but they are done either in parallel or after the build (I'm not sure). This same problem happens on my development machine running Visual Studio 2019 Enterprise.

I noticed that if no FakesAssemblies folder exists, one is created during the build, but the compilation fails because none of the *.Fakes namespaces were discovered. A second compilation/build works because now the FakesAssemblies folder is populated. One thing to note is that I took the dll file for Microsoft Fakes and put it in a NuGet package in our companies private feed, that way I can pull it down as a NuGet package instead of a reference.

SampleUnitTests.csproj:

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

  <PropertyGroup>
    <TargetFramework>net47</TargetFramework>
    <IsPackable>false</IsPackable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.1.0" />
    <PackageReference Include="Microsoft.QualityTools.Testing.Fakes" Version="16.0.28621.142" />
    <PackageReference Include="MSTest.TestAdapter" Version="1.4.0" />
    <PackageReference Include="MSTest.TestFramework" Version="1.4.0" />
  </ItemGroup>

  <ItemGroup>
    <Fakes Include="Fakes\*.fakes" />
    <Reference Include="FakesAssemblies\*.dll" />
  </ItemGroup>

</Project>
