Just a year or two ago I thought that learning WPF is the best use of my free time. Now though, I'm not so sure: seems like the number of ASP.NET jobs vs. WinForms/WPF is something like 10:1. Am I the only one noticing this, or is this really an overall trend? And should all thick-client developers drop everything and begin learning ASP....
I have used ExpressionBuilders here and there within my asp.net markup to return simple data types. Does anyone have any ideas how an ExpressionBuilder might be used to wire up an event inline?

hi 1) I noticed that after you close SqlConnection instance, you are still able to re-open the same connection: a) can you tell me what is going on behind the scenes?
