Alright, this is such BS! Why the H can’t Microsoft get a rollout right. Roll it out right or roll it back!

Anyways - here’s what I had to do to fix this garbage.

1: I had to uninstall all of the .net Core items in the “Programs” section of the control panel. 2: I went to https://github.com/dotnet/core/blob/master/release-notes/download-archive.md and got “2.0 sdk and 2.0 runtime” and installed that. 3: I ran my migration and got the same error as above but the version it was complaining about was “2.0” - SO, I added “<RuntimeFrameworkVersion>2.0.0</RuntimeFrameworkVersion>” to my project and the stupid thing worked.

I hope this works for any one of you - I worked hard enough on this project just to have a “Botched Rollout” reduce it to smoke!

Oh, and another thing - my “data” project borked because the file “<prjName>.EntityFrameworkCore.targets” was not cleared before it was overwritten. I had 2 ending nodes at the bottom of the file. I hope they fix THAT too.

(Sorry all, I wasted WAY too much time on this SNAFU and it didn’t have to happen.)

For anyone stumbling on this today, I had this issue on build.

Testhost process exited with error: It was not possible to find any compatible framework version

It was complaining of missing 2.2.5. It listed the installed frameworks which was indeed missing 2.2.5. So I installed the SDK which is 2.2.107 according to its MSI filename and that includes 2.2.5 of the runtime and it builds and no errors in the test output now.

I don’t get the version numbers.

I assume Testhost is a process and it wants to run on 2.2.5. Not sure which package the Testhost comes from but I had these referenced. I guess maybe I updated to 2.2.5 package reference but didn’t install the SDK (didn’t know I had to?)

    <PackageReference Include="Microsoft.AspNetCore.App" Version="2.2.5" />
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.5.0" />
    <PackageReference Include="MSTest.TestAdapter" Version="1.2.0" />
    <PackageReference Include="MSTest.TestFramework" Version="1.2.0" />
