LINQ to SharePoint

Why use LINQ instead of CAML

  • Intellisense
  • Compile-time type checking
  • You don’t have to know CAML which is not as well documented.
  • If you know LINQ to ??? you already have a good feel for the syntax.

Supported Environments

From what I can tell (I found conflicting information on this and I could not get it to work) you can’t use spmetal (which is required for LINQ to SharePoint) on SharePoint Online. However, if you are using SharePoint 2010 (on premise) it does generate ok, so I expect the LINQ to SharePoint would work as expected.
