I'm trying to use Windows Hello Authentication on my Unity/HoloLens2 App.
However I'm having problems with the very first step (checking availability), that's shown in Microsoft's example.
When calling Windows.Security.Credentials.KeyCredentialManager.IsSupportedAsync() the App loads a couple of dlls and just stops working.
It does not crash, no error messages. Just a couple of threads exiting with code 0x0 for many minutes (my longest test lasted about 15min, then I stopped the debugging).
Here is my C# code:
public static class KeyCredentialHelper
public static async Task<bool> CheckAvailabilityAsync()
bool available = false;
Debug.Log("pre await"); //Get's logged
available = await KeyCredentialManager.IsSupportedAsync(); //Application stops here
Debug.Log("post await"); //Doesn't get logged
Debug.Log("Only Available on UWP!");
I'm developing in Unity with the MixedReality Toolkit, so the compiler directives are necessary.
And here is the console output from within Visual Studio (after converting to c++):
(Filename: C:\buildslave\unity\build\Runtime/Export/Debug.bindings.h Line: 45)
'unity-project-authenticate.exe' (Win32): Loaded 'C:\Windows\SysArm32\CryptoWinRT.dll'.
'unity-project-authenticate.exe' (Win32): Loaded 'C:\Windows\SysArm32\cryptngc.dll'.
'unity-project-authenticate.exe' (Win32): Loaded 'C:\Windows\SysArm32\ncrypt.dll'.
'unity-project-authenticate.exe' (Win32): Loaded 'C:\Windows\SysArm32\ntasn1.dll'.
'unity-project-authenticate.exe' (Win32): Loaded 'C:\Windows\SysArm32\ngcksp.dll'.
Again, there are no errors, the App "doesn't crash" (It stops working and displaying it's content, but doesn't close).
When I close and reopen the App, a larger version of the loading animation of the HoloLens2 is displayed on eyelevel, but nothing else happens.
Visual Studio 2019
MRTK 2.4.0 (although this shouldn't have an effect)
What am I missing? Any help greatly appreciated!
