Lately, I've been working on getting my WCF for NETCF hello world BLOG posts (Intro to Messaging and the Intro to Store and Forward Messaging)  prepared for inclusion into Orcas.  I have both examples running and debugging with Orcas Beta2 and NETCF v3.5 Beta2.  The code has not changed much from the original Blog posts (I did fix a coding error).  I've back updated the two BLOG posts with the current code taken from the samples.
