Hi,
I'm looking for the best way to handle validation errors. I've seen many video's and read many documents but i still have doubts. I,m using WPF. EF, MVVM, .net 4.5.
My questions are:
Should i set the Code Generation Strategy of the EF model to DEFAULT or NONE?
Where to put validations of (table)fields.
Where to put general validation of a table.
How to make it possible to show that a field is mandatory.
How to make it possible to show that af field is not valid.
