I have set out on an integrated set of videos, tutorials and blog posts on the subject of using Expression Blend from the point of view of Silverlight 2 Programmers. To get things going, I created a 3 part video series based on ScottGu's extended blog tutorial and I have a tutorial on the topic due to publish early next week.
I am now in the process of creating more videos in which I will be exploring how Blend can make certain tasks far easier for the Silverlight programmer; keep an eye out for my video on Blend and Data binding.
I will express a certain resistance to starting this, and I've been trying to figure out why. Part of it is that I'm very comfortable in Visual Studio and much of it is that nearly all the books on Blend are targeted at Designers rather than at Programmers. It is my goal to overcome those concerns for developers who share these concerns, and to integrate Blend into my toolset; using Blend for its strengths, and Visual Studio where it is stronger, and, eventually, to think of them as two faces of a single semi-integrated tool.
I'm not sure what will happen when Visual Studio's design surface is fully read/write. I think by then I'll be so comfortable using Blend's features that I'll continue to do so for some tasks. I'd be interested in your experiences as well.
