I have a medium sized WinForm App (1 Form that hosts 40 user controls) that we use in house. I want to migrate over to WPF but I cannot do a Mass ReRelease.

My idea was, for now, to recreate the App 1 User Control at a time in WPF and have that hosted in the existing WinForm App. I would make them look nearly identical, at this point, so there would be no need for mass retraining.

My question is more to the point of, has any one else tried this and how does the data portion work.

I have recreated one of the WinForms User Controls as a WPF user Control. Do I need to publish that as a User Control Library?

How, then, would I access the DAL for that UC? I use a Linq to Sql data layer.
