WPF Validation Errors not showing on initial load of control or window

I was setting validation errors on the initial load of my view model, and to my annoyance the window would show up like everything was great.

Dotfuscator and KernelBase crashes, .NET crash with your application or service after obfuscation

Quick Tip: Don’t let Dotfuscator auto-sign your assemblies without specifying the key file explicitly. I spent the last hour beating my head into the wall, again, trying to figure out why Dotfuscator was creating a crap exe.
