It starting to feel a lot "Linux" doing WPF. I have to guess stuff. How could I know to set Width to "Auto"? Nothing in the gUI. It doesn't even make sense, I mean, I already set the HAlign to stretch! Why do I have to even do this? WHAT IS WRONG WITH THE GOOD OLD ANCHOR PROPERTY? WHY THE CHANGE?

...omfg, WPF sucks big time so far. Totally unnatural/unlogical compared to what "we are used to" from winforms.

Do you feel the pain as well?
