Create Custom Membership Provider (Entity Framework vs Linq)

I'm starting work on a Custom Membership provider and I was wondering which option would be the best to develop this application in Linq or Entity Framework?

Also I have a need to link two table from different database via a common ID and I was wondering does anyone know of any good tutorials about creating a MVC 3 Web Application that uses either Linq or Entity Framework to do this.

From my research Entity Framework seems to be the best method suited to my situation but I would app开发者_JS百科reciate some advice / confirmation that this correct and a little direction to a tutorial is possible?

By Linq, you mean Linq to SQL vs. Entity framework? If so, then I would recommend using Entity Framework. Microsoft's development on Linq to SQL has virtually stopped so EF has a better future.

NerdDinner is one of the more popular tutorial applications that uses ASP MVC 2 and entity framework. ASP MVC 2 is similar enough to get started with the basic concepts. Here is a good walk through tutorial:
