C# - exercise - object validation - reflection - generics

just published (GitHub) a C# example for object Validation, for this purpose I decided to use the .NET Reflection and tried to use Generics.

Here's the code: http://ift.tt/2wzDzH4

The exercise is working, but I would really like to improve coding, that's why I'm looking for your feedbacks / reviews / improvements and also new features to implement.

More than happy to be in touch with any of you :)
