✅ WPF - how to correctly call a method in the ViewModel when an event occurs in the View?
Simple answer, a event handler has no return type. The method should look like this: private async void MyToolWindow_LoadedAsync(object sender, RoutedEventArgs e) But the right way with a viewmodel is the MVVM Pattern. https://learn.microsoft.com/de-de/archive/msdn-magazine/2009/february/patterns-wpf-apps-with-the-model-view-viewmodel-design-pattern

allIds.Select(x => x.Id).Intersect(higherHierachyIds.Select(x => int.Parse(x));
allIds.Select(x => x.Id).Intersect(higherHierachyIds.Select(x => int.Parse(x));
that should work (not tested)

Especially when you operate on several different platforms.

I think the class mainthread is the way to go.

Hi, you could try to get a reference of the UI thread through the SynchronisationContext class https://learn.microsoft.com/en-us/dotnet/api/system.threading.synchronizationcontext?view=net-7.0 In the constructor store the SynchronisationContext.Current value in a Private filed. So you can call the Post mehtod in your Event handler to execute the passed method on the UI thread.
