Sorry for being rude, maybe I treat people badly on the internet but I can still apologise. I was just quite annoyed because we've had a lot of success with WPF. Sounds like you didn't.
So how big was your project? What machine were you building on? Ours has 38 windows and 25 user controls, but a lot of the meaty code is being run on a server and is separate to the app (over wcf). We have 3 projects as part of the application, and on my core 2 duo 3ghz it takes about 15 seconds for a full compile. (However on a previous machine 2ghz I think it was starting to take a lot longer).
I did actually have a lot of issues with VS2008 running out of memory and the occasional crash, but that was only before we found and fixed a lot of the memory leaks, and removed all of the calls to "initialisecomponent()" in the constructor. And removed all of the on_load code so that it wasn't being called in the designer! Now everything is much much faster. We didn't use expression blend at all and tried our best to cut back on most of the eye candy. People are running our app on pentium III's and it's ok.
Well apparently VS2010 is going to use WPF - I can't begin to imagine how system-intensive but I'll have to wait and see.
And I completely agree - I'd love to see if control panel or wordpad were to be re-written by MS in WPF and to see how it goes.
