I use the VS Professional 2019 Version 16.7.7 and latest Xamarin.Forms. Work only with Android part on Windows 10. I have the simple blank app with one MainPage and one MainViewModel, where the viewmodels part implemented as separate assembly. In the ctor of viewmodel I initializes test string, which show on UI via Binding. And the issue in the next: when I start application first - everything is okey, but if I change some code in the ViewModels assembly (for example - change test string value) and relaunch - application not apply these changes without clean/rebuild solution. And even breakpoint show the old property value.
I leave the GD link for my solution, if someone want to try to reproduce issue https://drive.google.com/file/d/1507isz5lX_U6204y5o0_maq7ehBeHKFq
Waiting for helps. Thanks.
