Description

Trying to store local data permanently in Xamarin Forms WPF, but as soon as we stop the program and then restart, all the settings are gone. This works correctly in UWP and Android

Steps to Reproduce

1. Create a new WPF project.

2. Add the following code to the MainWindow class:

       object Test = null;
       bool found = Application.Current.Properties.TryGetValue("Test",out Test);
       Application.Current.Properties["Test"]= "TestValue";
       Application.Current.SavePropertiesAsync();
       found = Application.Current.Properties.TryGetValue("Test", out Test);
   

3. Start the program (the value should be stored permanently)

4. End the program, restart and check the value Application.Current.Properties.Count in debug mode. It is 0, but should be 1.

Expected Behavior

The value "TestValue" should be stored permanently in WPF.

Actual Behavior

On every restart of the program, the valus is gone.
