Hello,

with bug 18640 fixed, .NET 3.x/4.x WPF based apps now run into a message
deadlock between main UI app thread and renderer thread.

When the d3d9 device is created, the window handle created by main UI thread is
passed.
The pixel format is propagated synchronously to target window.
Because the target thread waits for event without pumping messages (by design)
it deadlocks.

Easy to reproduce with small example app:

Prerequisite: clean WINEPREFIX and 'winetricks -q dotnet30'

Regards
