Peter Foot talks about the .NET Compact Framework Wiki we've set up at OpenNETCF.org. Originally, I installed FlexWiki, but that has some cross-browser issues that we really didn't care for.
We're hoping that this will become the new home for the .NET Compact Framework FAQ since Geoff Schwab has moved on to pastures new. Also, we're taking a leaf out of Adam Nathan's book and are providing a wiki section on P/Invoke with the .NET Compact Framework. This is going to be fairly comprehensive in the end as it will also provide a pointer to the managed classes available in the .NET Compact Framework and the Smart Device Framework which already wrap those particular APIs. Now that's cool info to know.
Feel free to head over to wiki.opennetcf.org and add/edit stuff! Ultimately, it's our contributions which will drive this thing forward.
