In addition, two books cover this quite well...The Compact Framework Core
Reference by Wigley and Wheelwright and The Definitive Guide to the Compact
Framework by Fergus and Roof. They both do a great job (with working
examples) on how to do this, and both are excellent in many different areas.
Also, Building Solutions with Microsoft .Net Compact Framework, Best
Practices for Mobile Development does a good job of discussing it.
BTW, Dan and Larry's book has some working Crypto examples in regard to your
other question.
