Azure DevOps enhanced support for Microsoft.Testing.Platform, from running tests to publishing results!

It starts the way these things always start.  A red build. A failing test. And that quiet, sinking feeling of “This worked yesterday.”  Meet Sam. Sam’s not a junior, not a rockstar, just a solid developer who’s shipped enough code to know that bugs don’t care how...

Something is forcing it down an alternate path.
