Support .NET Validation Attributes
It would be great if the .NET validation attributes defined on the business model were sent along with the metadata. One benefit of this feature would be that we wouldn't have to redefine error messages on the client side.
A quick update for this request:
We’re probably 50% there today, but hope to get to 80% soon. This is certain to get done, but we’re just not there yet.
I got this working (DisplayNameAttribute) using the solutions on stackoverflow

Please, support custom validation attributes too.

It seems like just Display("Product Name") and perhaps ErrorMessage is the only major ones left to be implemented. At the moment we are just letting them be displayed in ugly camel case, eg "productName is required" until we get this functionality.

Hello good people at IdeaBlade. Any progress on this excellent suggestion? Thanks for your great product!
By the way - - I've noticed that this suggestion is not "Under Review". Does that mean that it's not being considered?

Hi there? I wanted to check on the progress on this feature. Thank you for all your hard work.

In particular, getting the DisplayName attribute value (if nothing else yet) would be most valuable, as then they can be displayed to the user in validation error messages instead of property names.

seems like this will be a major improvement.

Am I missing something here? I believe the in-built attributes like [Required], [MinLength] etc. are available out of the box. If you use Entity Manager's saveChanges method, Breeze will throw the exception the way it would do on the server side.
Good idea. It is important that Breeze support .NET validation attributes, for example "DisplayName", "ErrorMessage", "ErrorMessageResourceName"... etc.
