TechEd Day 3
Most interesting session for me today was on '_Offline Caching and Synchronization with a New ADO.NET Sync Framework'. T_his can be summed up as making Smart Client applications behave like Outlook i.e. occasionally connected, but all done without the user having to be involved. Thus allowing the application to run on less than reliable networks whilst keeping a central store of data up to date.
Historically this is problematic to achieve but with the new ADO.Net framework extension that has just gone to RC status it can be done in a few lines of code. For more details have a look at http://blogs.msdn.com/stevelasker/
