I was just revisiting Application Architecture Guide on CodePlex and found Technology Cheat Sheets (look under Appendix) excellent reference when deciding about which technology to use in a certain part of your application. So go check the details about pros and cons of a certain approach under these links:
- Cheat Sheet - Presentation Technology Matrix
- Cheat Sheet - Data Access Technology Matrix
- Cheat Sheet - Workflow Technology Matrix
- Cheat Sheet - Integration Technology Matrix
Again great stuff and reference that somehow can get neglected (who looks all the way to appendix, right?), but definitely worth to look at if you are designing a new application architecture on Microsoft platform.
