EntLib 4.0 Validation Application Block and Unity Screencast

In my last screencast I talked about integrating the Data Access Application Block with Unity:



In the following screencast on the Validation Application Block in Enterprise Library 4.0:



we don’t need to discuss Unity Extensions like in the previous screencast, because we can get really nice injection of validator classes, such as IValidator<Customer>, into our custom classes by creating a simple wrapper around the Validation Application Block and registering the wrapper with Unity.


The screencast shows how to create a simple wrapper around the Validation Application Block, register it with Unity.RegisterType, access the custom validator classes via Unity.Resolve, and have Unity inject those validator classes into custom classes, such as an AddCustomerPresenter Class. The same techniques will work if you are using the ASP.NET MVC Framework and injecting validator classes into a Controller.

Thanks for all the positive feedback on the previous screencast :) Enjoy!
