MSBuild tip: if you're working with binlogs, set the environment variable MSBuildLogPropertyTracking=15.
It enables logging of where each property was initially assigned from during evaluation and lights up more features in the binlog viewer.

Oh how I wish Microsoft would hire you (no matter the price) to simply fix shit in windows. Free reign. "Bruce, we don't want to see you, just the commits, fix stuff. We'll pay whatever you want" It'll be beneficial for all.

Some great charts on #AI from the Wall Street Journal. t.ly/xvvbw "AI products would have to create an additional $650 billion a year, indefinitely, to give investors a reasonable 10% annual return. That’s more than 150% of Apple’s yearly revenue"

Trying to measure coding productivity is, and always will be, a fool's errand.
Why? Because I can go for a walk then take a shower and have an idea, then write a single line of code that fixes everything I was working on.
Immense productivity, but by most metrics I didn't do anything at all.

AI PRs where the author doesn't have an understanding of the system shift the burden of understanding onto the reviewer.
So now it's on the reviewer to gain an understanding of this area to either confirm or refute. The author saved time at the expense of the reviewer.

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?)
