NotifyDataErrorInfoAdapter does not exist

Apr 14, 2014 at 1:23 PM

The Examples on your project home page include an implementation of a validation base class for INotifyDataErrorInfo. But, the NotifyDataErrorInfoAdaptor doesn't seem to exist. Am I missing something here?
public class ValidatableViewModelBase : INotifyDataErrorInfo
    protected ValidationHelper Validator { get; private set; }
    private NotifyDataErrorInfoAdapter NotifyDataErrorInfoAdapter { get; set; }
Thanks in advance,

Sorry for the late reply. Apparently you are referencing a .NET 4.0 version of the assembly, but the INotifyDataErrorInfo interface was introduced in .NET 4.5. You need to reference a portable version of the MvvmValidation.dll assembly that targets .NET 4.5, Silverlight 5, Windows Store apps and Windows Phone 8.

im running .NET 4.5 and trying to use the latest version with INotifyDataErrorInfo. when trying to use nuget to install the package, it only ever picks the net40-client framework, not the portable one. so i have to manually remove/add the reference each time there is an update. the only information i found about it is that nuget internally picks specific frameworks over portable ones.
