after updating Xamarin Forms to 188.8.131.52203, we have problems with our MasterDetail-Pages in UWP. As our Project requires "navigatable tabs", we have a TabbedPage and inside each Tab, we put a NavigationPage with a MasterDetail-Page. You can easily recreate this, by creating an example Xamarin-Forms-Project (not shared!) and modify the MainPage like following, so it becomes a TabbedPage:
<?xml version="1.0" encoding="utf-8" ?> <TabbedPage x:Class="PlayGroundMDTabbedPage.MainPage" Title="Playground"> <NavigationPage Title="Page1"> <x:Arguments> <local:Page1 /> </x:Arguments> </NavigationPage> <NavigationPage Title="Page2"> <x:Arguments> <local:MasterDetailPage1 /> </x:Arguments> </NavigationPage> </TabbedPage>
When you start the project, in UWP it seems, that the MasterDetail-Views are somehow collapsed. When we remove the NavigationPage, all is fine.On another platform, the layout is, what we expect to see.
The UWP issues arose after updating Xamarin Forms to v2.5. When we downgrade to v2.4, everything is working perfect in UWP. As we need "inside-tab-navigation", we cannot do without the NavigationPage. So my Question is: is this XamarinForms v2.5 intended behaviour? How can we fix the Layout in UWP?
Thank you very much in advance!
