Video Rendering Issues for WPF Windows



Recently I ran into a few reports of black screen of death rendering of Markdown Monster when starting up from a very few users of the application. They reported the screen just shows black, while actually being responsive to moving and showing menus etc. Also moving to another screen often fixes the problem. It turns out this is a hardware related issue with WPF with certain video hardware/monitor combinations. In this post I describe the problem and the workaround to get the application to render properly even on compromised hardware.

Empty SoapActions in ASMX Web Services



Recently I had to deal with an ASMX Web Service that was receiving empty SoapActions from the client. ASMX doesn't like that, but luckily there's an easy work to strip out the errant Soap header.
