This will be the one to re-watch when you're optimising your application, or befuddlement arises as stated by Adam because your application is slow and you don't know what the problem is. Some of the issues covered are available at; http://blogs.msdn.com/jgoldb/archive/2007/10/10/improving-wpf-applications-startup-time.aspx

Very good indeed.

This is truely excellent, really good to see this kind of thing on Channel 9.

With regards to the text rendering, did any of the DX10 specific optimizations ever arise? A long time ago, in the Avalon days, i remember there was talk of moving the text path completely to hardware in DX10 class video cards, as opposed to the mixed hardware cleartype and software glyph composition / alpha blending in DX9 paths?

Thanks for the kind words all!

At this time, our hardware rendering is (still) DX9. Taking advantage of geometry shaders etc is still certainly interesting, though I can't say one way or the other if/when we'll move to DX10.

Why can't you guys remember to post a link to the LOW-RES file on every video that you do?

It's very irritating when downloading with BITS to have to wait on 600Mb files.
