Description

This is a repros project to demonstrate an issue with touch and .NET Core. This requires a touch enabled device.

The issue is that if a splash screen has been shown in another thread, then touch is not working in the main window. This works in .NET Framework, but not .NET Core 3.1.

How to use

1. Open project file
2. Set target framework to netcore3.1
3. Build and run
4. Touch/tap the white area.

• Actual: One event is shown, PreviewMouseDown. Touch scrolling does not work

.NET Framework.
