How use async API in UWP (XAML) project with Monogame 3.8

1

Hello. I’ve problem with calling async API (for example Windows.System.Launcher.LaunchUriAsync) in Monogame 3.8 (UWP, XAML). API works in Initialize method but doesn’t work in Update. I think, it relates with work in different threads.
I checked calling API in UWP (XAML) with 3.7 and Desktop and UWP (CoreApp) projects with 3.8 version of Monogame - API works well.
Where is my fault?
How should I call API in UWP (XAML)?

Hey @Denis_S, Welcome to the Community!

While I may not be correct but you cannot thread the Update calls and the Draw calls together…

I will be keeping track of this and if no further help, I will play with it myself specifically for data handling.

Happy Coding!

According to the Microsoft docs (https://docs.microsoft.com/en-us/uwp/api/windows.system.launcher.launchuriasync) “this API must be called from within an ASTA thread”.

To achieve this change this code:

await Windows.System.Launcher.LaunchUriAsync(new Uri("https://www.monogame.net"));

To this:

await Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(
    Windows.UI.Core.CoreDispatcherPriority.Normal, async () => { await Windows.System.Launcher.LaunchUriAsync(new Uri("https://www.monogame.net")); });

Hope that helps.
