.NET database connection

I'm applying for a .NET developer job and they're going to test me this Monday or Tuesday. Given that my only knowledge of .NET is a little C# (which is mostly based on my C knowledge), I'm in pretty deep shit.

They tell me that it's going to be something easy, like accessing and updating a database (SQL probably) using the framework. How is that accomplished? Google says that you can use LINQ or ADO.NET but a friend of mine recommends NHibernate.

NO EXCEPTIONS

LINQ is ok.

Don't bother with NHibernate, it's based on Hibernate for Java, it's a third-party library which is an ORM layer for RDBMS. ORM = shit scalability. Object orientation doesn't make everything good.

Just stick with ADO.NET and LINQ (System.Data.*).

The .NET Framework libraries are similar in scope and functionality to the Java or Cocoa libraries. So pretty much anything you want to do for an enterprise project can be done with the .NET libraries, without need for 3rd party shit.

You seem like the perfect .NET developer.

just tell them about NoSQL's superiority!

Thanks a lot.
