Custom Controls and Windows

I am trying to learn some more about custom controls in wpf. I am using Microsoft Expression Blend. I have found some tutorials online but most of them seem to leave out alot of details or are very basic a chimp could do it. The other problem is that they dont actually show you the code to add it to the form. They just show you how to do it in xaml. If anyone has any good custom control tutorials please post here for me to see.

Also I would like to learn more about customizing windows in wpf. I have just broke the surface on that and it seems very highly customizable but not very easy. I have not been able to find any tutorials on this so if anyone finds one please post it here as well.

Thanks in advance for any help. I know a little about customizing in wpf so if you have any questions just ask.

When you say customising windows, the best approach I have found is not to try and customise the actual window but just set the window border and background etc to transparent. Then use another control to act as your Window (but your window is still there of course, its just invisible) - for example using a Border then you can set things like the corner rounding and a nice gradient etc and put whatever you want inside the border to make it look like a window border (like I have done in this app: http://www.vbforums.com/showpost.php...3&postcount=42 )
