I believe it would be preferable if this section:

opencvsharp/src/OpenCvSharp.Extensions/WriteableBitmapConverter.cs

Line 351 in a5698de

dst.Lock();
also called AddDirtyRect before unlocking.

If the backbuffer is updated directly, rendering is not updated. This is inconsistent with the behavior of WritePixels and there is no way to know, outside of the method, which update method was chosen.
