Url: http://wilderminds.blob.core.windows.net/downloads/testef.zip

I've been digging into the latest version of the Entity Framework Beta (and designer CTP) that dropped a few days ago. I've concocted a small example that shows the derivation model in the Entity Framework.

Entity Framework June CTP Now Available

Url: http://blogs.msdn.com/adonet/archive/2007/07/02...

Orcas March CTP Released

Url: http://www.microsoft.com/downloads/details.aspx...

I've gotten the new Visual Studio Orcas March CTP up and running (as the VPC it ships as).  I've been playing with the Entity Framework some today and I am pretty impressed so far. Unfortunately the automatic generation of the schema/mapping files still isn't working in this build, but if you write it out by hand it does work.  I'll be posting an example soon.
