Hi guys, I've the same proble as Krisztian. In attachment my output of the ps script msbuild-versions.txt

I have some XUnit tests that I run from Test Explorer. They use the MS Build NuGet packages to build a project file at test time. These were passing before the upgrade to VS.

After the upgrade, they all started failing with the error reported in this thread.

I managed to get them passing again by updating the referenced MSBuild nuget packages from version "15.7.179" to version "15.8.166".

To replicate, create a test, pull in the package references shown below, and set these environment variables, then try and build an SDK style project.

Environment.SetEnvironmentVariable("VisualStudioVersion", "15.0"); 
Environment.SetEnvironmentVariable("VSINSTALLDIR", "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community");
Environment.SetEnvironmentVariable("MSBuildSDKsPath", "C:\Program Files\dotnet\sdk\2.1.103\Sdks\");

<PackageReference Include="Microsoft.Build.Utilities.Core" Version="15.7.179" />
<PackageReference Include="Microsoft.Build.Framework" Version="15.7.179" />
<PackageReference Include="Microsoft.Build" Version="15.7.179" />
<PackageReference Include="Microsoft.Build.Tasks.Core" Version="15.7.179" />
