Hi,
I am facing a problem on Hololens 2 (10.0 version 1903) with your example.
I installed the ARM package with its dependencies (Microsoft.NET.CoreRuntime.1.1 and Microsoft.VCLibs.ARM.Debug.14.00)
I restarted the Hololens 2 and start MyApp application.
When requesting the url /myapp/api/status, I get the following exception :
System.IO.FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E)
at System.StubHelpers.StubHelpers.GetWinRTFactoryObject(intPtr pCPCMD)
at Windows.System.Diagnostics.DevicePortal.DevicePortalConnection.GetForAppServiceConnection(AppSerciceConnection appSerciceConnection)
at MyApp.App.OnBackgroundActivated(BackgroundActivatedEventArgs args
Any idea ?
