• #187 #188 Apply the "override" access modifier to a column. The override modifier is required to extend or modify the abstract or virtual implementation of an inherited method, property, indexer, or event. Thanks to Pastor Quintero.
• #189 #190 Setting the DbContextInterfaceName to an empty string "" will cause the generator to not create or use the interface. Thanks to Pastor Quintero.
• Automated setting of TargetFrameworkVersion. No longer do you need to set the target framework version, which is used to determine if the generator should create Async methods for you. This is automatically detected now.
• #196 Support C# 5 language for FakeDatabaseContext. Thanks to Ralph Mack.
• #198 Pass in the StoredProcedure class to StoredProcedureRename instead of the name. Thanks to ichalyshev.
