    just add this to your App.cs file

        public bool IsShuttingDown { get; private set; }
    
        public new void Shutdown(int exitCode = 0)
        {
            this.IsShuttingDown = true;
            base.Shutdown(exitCode);

            }
            catch (Exception)

                return true;
            }
        }

    There is Application.Exit event, you should be able to do with that.

    If you really need it to be a property, then create a property into your App class (your class inheriting Windows.Application) and set it to true in with the Application.Exit event.
