SimpleMembershipProvider in MVC4 for MySql, Oracle, and more with LLBLGen
One of the cool new features in ASP.NET MVC4 and the Visual Studio MVC application template is the SimpleMembershipProvider which provides a more concise membership provider to the ASP.NET framework, and supports OAuth additionally. Thanks to LLBLGen we can generate one provider code-base that supports a dozen or more database providers out-of-the-box, eliminating the out-of-the-box limitations imposed by Entity Framework as the data access strategy, and lots of custom SQL commands built for SQL Server.
