I am excited for #dotnetconf, I've secured a spot for a talk and will show the best new things in #dotnet test and #mstest. Hope that you join me to see the cool stuff we've been working on throughout the past year. (It is on day 2).

Now that #dotnet code coverage will be coming to #visualstudio professional 2026, is there perhaps also any info on Testcase Impact Analysis ( #TIA) for #azuredevops CI/CD pipelines (as far as I can tell it was never supported for .Net Core?)

Ran into the situation again where updating VS broke incremental builds, because a different compiler version is now being stamped into the embedded PDB, invalidating all caches and resulting in different PE file bytes from identical sources.
Glad I invested in the fancy PE parser and differ!
