Late last night (or early this morning), I submitted my first ever patch. Hopefully this is the start of a long line of contributions. It fixes a problem in Monodevelop with the Code Template drop-down in the options panel. It’s bug #78082.
Every day I work on my soon-to-be-announced project I get more confident in C#. For anybody learning C# on linux with Mono, I recommend you look at Banshee for an example to help you along. The ActionManager class is very helpfull. Here is another good resource for tutorials. And lastly, You can go to the Mono Project sight for a good intro to the Gtk Treeview widget. Treeview is a beast at first but is really nice once you get the hang of it.
