Hope this hasn't already been blogged about (I've been out of the loop for a bit), but the “Improving .Net Application Performance and Scalability” document has recently been released in tis Beta 2 form. Its an excellent piece of work from the patterns and practices team and I encourage you to contribute to its development.
I had blogged on the book last month, but didn't realize a Beta2 version had come out. Thanks!
This is great stuff. This is the kind of stuff that we need to come out of Microsoft for us Architects to do our job.
Thanks for the comments guys. I agree whole heartedly Sam. It makes it so much easier as Architects to create quality solutions for our clients.
