Maybe you didn’t notice that Windows Embedded CE Developer Center web site has a Learn section: in this section you can find a lot of interesting content in various formats (video, text, slide presentations, MSDN links, etc.) about several Windows Embedded CE development areas, specifically:
- General Content
- OS Design & Build
- BSP & Other Hardware
- Application Development
- Communication & Connectivity
- Silverlight for Windows Embedded
For each area you can find entry-level, intermediate and advanced content.
Some of the things you’ll find aren’t really new but the I think that having a lot of interesting information concentrated in a single site is valuable. From the same site you can download the free guide to Windows Embedded CE Exam Preparation Kit written by MS and Adeneo and a free electronic copy of Windows Embedded CE 6.0 Fundamentals book, by Stanislav Pavlov and Pavel Belevsky.
