Linq's missing link
I came across this library today and it rocks. http://www.albahari.com/nutshell/linqkit.aspx
Without this library trying to pass Linq Expressions into Where clauses on Linq to Entities just didn't work beyond some very simple (trivial) examples.
With this library I can now combine multiple filter function expressions and pass them to my query, and it works as intended:
Expression<func<datetime,bool>> contains = ts.Contains;
var query = from caller in dataContext.CallerIDLogs.AsExpandable() where contains.Invoke(caller.DateTime) select caller;
