Right now MSBuildDebugEngine turns on three things:

  1. Injected binlogs for all evaluations and builds.
  2. MSBUILDDEBUGCOMM traces for node-connectivity debugging
  3. MSBUILDDEBUGSCHEDULER traces for scheduler debugging.

msbuild/src/Framework/Traits.cs

Lines 33 to 34 in 371d00f

DebugScheduler = DebugEngine || !string.IsNullOrEmpty(Environment.GetEnvironmentVariable("MSBUILDDEBUGSCHEDULER"));
DebugNodeCommunication = DebugEngine || !string.IsNullOrEmpty(Environment.GetEnvironmentVariable("MSBUILDDEBUGCOMM"));

Binlogs are super useful, and the reason we ask for this in like 99% of cases.

Comm traces can be helpful if we're having trouble with process launching or named pipes.

Scheduler traces . . . I can't remember ever getting useful info out of.

Should we drop scheduler traces from this list?
