For the lazy ones that did not put a try-catch:

Press ctrl+alt+q and re-evalute this expression.

((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors

For the less lazy ones:

catch (DbEntityValidationException dbEx)
{
    foreach (var validationErrors in dbEx.EntityValidationErrors)
    {
       Trace.TraceInformation("Entity of type \"{0}\" in state \"{1}\" has the following validation errors:",  validationErrors.Entry.Entity.GetType().Name, validationErrors.Entry.State);
        foreach (var validationError in validationErrors.ValidationErrors)
        {
            Trace.TraceInformation("Property: {0} Error: {1}", validationError.PropertyName, validationError.ErrorMessage);
        }
    }
}

And if you don't like exceptions:

var validationErrors = model.GetValidationErrors();
var h = validationErrors.SelectMany(
x => x.ValidationErrors.Select(
f => "Entity: " +(x.Entry.Entity) + " : " + f.PropertyName + "->" + f.ErrorMessage
));
