Crash during Drag and Drop operation error 0x80004005

Describe the bug

When performing a Drag and Drop operation on a DataGridRow, an error is thrown at random times.

Steps to reproduce the bug

Steps to reproduce the behavior:

1. Build the attached project and run
2. Select test from the nav menu
3. drag an item in the datagrid and move it around the datagrid and the desktop (in and out of the app window)
4. Observe the MANY error generated in the debug window
5. Eventually the debugger will break due to Reentrant code exception

Note: Adding more UI panels in the XAML to nest the DataGrid deeper in the hierarchy causes the issue to manifest faster and generates more errors in the debug window. The eventual crash seems related to manipulation of the Margin property of the DataGridRow. (Uncommenting the return at line 62 of TestView.xaml.cs seems to avoid the crash). The code that triggers the crash is being dispatched asynchronously, and is locked with an AsyncLock. I am unsure if this crash is related to the DataGrid, or is more generally relalted to Project Reuinion

Additional context

@codendone This is unacceptable. How can this crash still be in a so-called ‘stable’ version? We have thousands of users relying on drag/drop to work. How long do we need to communicate that this is a Microsoft issue that will be solved in some later version? Can you please make some workaround or make a silent fail without crashing the app?

@codendone Thanks. Good to have it fixed finally. This is bad news for our app and customers. We plan to release in a few months and drag & drop is a key feature of our app. The 0.8 release should support Drag & Drop, but obviously it doesn’t. Is there no way to make the drop fail without crashing the app in the mean time?
