Compiled app does not run after updating Visual Studio 2019 to 16.3

Compiled app does not run after updating Visual Studio 2019 to 16.3

BY 14 Oct 2019 Tizen .NET

All compiled app with Visual Studio 2019 16.3+ crashes on launching.

Even a template-generated app with Xamarin Forms default settings(Tizen Wearable Xaml App) crashes as soon as launching.

Call stack :

> __kernel_vsyscall
  ???
  ???
  ???
  ???
  ???
  ???
  coreclr_execute_assembly
  tizen::runtime::dotnetcore::CoreRuntime::launch(char const*, char const*, char const*, int, char**)
  main
  ???
  _start

Visual studio debugging mode shows a just “Unhandled Exception” without any detaled message

Seems to be related with Xamarin Forms.

An app compilied on Visual Studio 2017 works well.
