Describe the bug
I have a very basic repro for a memory reference exception calling Geolocator.GetGeopositionAsync() from a new WinUI3 project on Windows 10 18363. The initial call to Geolocator.RequestAccessAsync() succeeds, but the followup call to GetGeoPositionAsync() always crashes in both x86 and x64 modes with the following messages in the output window:

AsyncCausalityTracer : System.InvalidCastException: Unable to cast object of type 'WinRT.IInspectable' to type 'Windows.Foundation.Diagnostics.IAsyncCausalityTracerStatics'.
   at System.Threading.Tasks.AsyncCausalityTracer..cctor()
Exception thrown at 0x00007FFD8434C330 (coreclr.dll) in WinUIAccessLocationTest.exe: 0xC0000005: Access violation reading location 0x0000000000000010.
The Common Language Runtime cannot stop at this exception. Common causes include: incorrect COM interop marshalling and memory corruption. To investigate further use native-only debugging.

This crash does not happen without a managed debugger attached. With no managed debugger attached and a native debugger attached (run without debugging then attach a native debugger to the process), I can catch a EEMessageException with the following massive stacktrace:

I have once observed a 0x0006 location address.

Steps to reproduce the bug

  1. Clone repro from https://github.com/mqudsi/WinUICrashingAccess
  2. Open in Visual Studio 16.7.0-Preview1 on Windows 10 18363
  3. Place a breakpoint on await locator.GetGeopositionAsync()
  4. Debug
  5. When breakpoint is hit, press F10 and observe crash

Version Info

Windows 10 version Saw the problem?

(Side note: with UWP, I could use Visual Studio to debug only native code and inspect this inspection. The project template generated by the WinUI VSIX template only gives me an option to additionally debug native code (although it seems even with it unchecked native code is still debugged!) but does not give me an option to debug only native code.)

@mqudsi, thanks for filing this issue! It looks like you found a duplicate in the C#/WinRT repro, is that correct? If so, I'll just close this out.

Not sure if this is necessary information or not, but #2716 seemed related since it only happened when the debugger was attached.

Closing as it is dupe of (fixed) CsWinRT issue mentioned above.
