MVC 4 EF connectivity With DB2/400

Purchase a third party data provider designed for Entity Framework. Progress software's Data Direct is super easy to use. I don't like how their server licensing works though because their server license is per core processor for your app server. This is flawed because this assumes you only have one app server when in reality, people regularly need to have different app servers for load balancing. I would prefer they just license per one ISeries server. However, you can purchase the licenses for each individual user if you decide to do that.
