Microsoft Testing Platform GitHub and Azure DevOps Reporting
I’ve previously written about how cool Microsoft Testing Platform is, which is a set of libraries that a lot of Unit Test frameworks such as xUnit, TUnit, MSTest and more build on. To standardize how ...

Super cool! With a few flags it now reports tests and code coverage.
Screenshot showing how I appied arguments to the dotnet run CLI in a Cake Build Frosting project.

It shows adding the flags: `--report-trx --report-trx-filename {asm}_{tfm}_{time}.trx --publish-azdo-test-results --report-azdo-upload-artifacts files --coverage --coverage-output {asm}_{tfm}_{time}.coverage --coverage-output-format cobertura --diagnostic`Screenshot from the CI run in Azure DevOps Pipelines showing the Test tab with results from the run.

Epic. I've been using ctrf for this in GH. Nice to see it come out of the box now. Have to try it in AzDo soon!

Just a hassle to support if you want to use newer versions of the C# language. Then again if this project is targeting older stuff currently, migrating project structure and keeping netstandard around should work just fine.

Tomasz Cielecki @ostebaronen.dk · 14/07/2026
I'd skip netstandard and just do net8.0 as minimum target. Do you really want to keep net45 support around?

Tomasz Cielecki @ostebaronen.dk · 14/07/2026
With MvvmCross I had to keep a separate library for WPF and UWP support because they don't coexist that well. Otherwise everything else crams fine into one multi-target lib.

Tomasz Cielecki @ostebaronen.dk · 14/07/2026
Won't be coreclr if you run NativeAOT. I don't envision anything breaking between net10 and net11 if so the runtime is broken. Instead of bait and switch I'd work towards a multi-target lib instead. Haven't checked the code, but I assume there is no UI but just MIDI control code?

Cool! I used to like the JerBrains IDEs but switched to VS Code for .NET because of the horrible slowdowns in Rider. Hope improvements are made in the future because the refactoring tools and just the overall experience is really good.

@vscode.dev is there a way to select "auto" model in the agents window. I don't seem to see that option? Also. There is only agent mode? If I need to plan I have to write `/plan` is this normal?
