…rocess termination On .NET 8+, use the built-in Process.Kill(entireProcessTree: true) instead of spawning a separate taskkill process on Windows. This reduces process cleanup time from ~420ms to ~60ms (7x faster), significantly speeding up tests that spawn child processes. The taskkill-based approach is retained for .NET Standard 2.0 where Process.Kill(bool) is not available.

This shaves a minute or two off overall test execution.
