I'm about to start a new .net web project. Previsouly for my n-layer web apps i've used the "Microsoft Data Access Application Block" (sqlhelper.cs) for the data access, then an interface class to interface with the object classes. I'm aware this technique is a bit dated and was looking to use something a little more with the times.
I've looked into LINQ to SQL for data access but was restricted by lacking the many to many relationship. The entity framework was a whole differnet approach that appears to have too larger learning curve.
Would there be anything wrong with using the sqlhelper.cs class to handle my data access?
