Since the first coffee meeting I have been hassling Alan to start blogging. After migrating the user group's website across to Community Server I was able to set a blog up for him and he just submitted his first post. One of the pain points for a number of mobile developers is what to use for logging. Most developers end up doing their own custom solution. At Intilecta we ripped out most of the useful bits from the Patterns and Practices Enterprise Library. Based on what Alan has to say in his post I think I would definitely look at log4net as it seems to be quite comprehensive and it runs on the .NET Compact Framework.
