I'm running umbraco successfully. I recently uploaded some new files into the App_Code folder, basically some data access classes that I use in a custom made user control. But I'm getting a compilation error for the linq namespace. here's the site: http://sweetcom.w02.Winhost.com/
Yes, the assembly with the error is System.Data The compiler says .net framework 2.0 in the screen. Shouldn't it be saying 3.5?
No. That's misleading. .Net 3.5 is essentially an extension of .Net 2.0. It uses the same engine as .Net 2.0 so it will say .Net 2.0 when it throws an error. But to get it to run .Net 3.5 framework is to essentially code for it.
What Pipeline mode are you running? Is it Integrated or classic? Have you tried switching between the two as a test?
