Research direction

Start with Interop/COM/NativeClients/Dispatch/Dispatch.cmd and the linked console log, then reproduce it with CORE_ROOT set as shown. Trace the dispatchCoerceTesting->Invoke failure and compare the returned value with the test's expected 100; done means the Dispatch test completes successfully without the 0x80131516 failure.
