推荐答案
关于can it be that 0 errors and IsValid == false":这里是 https://github.com/Microsoft/referencesource/blob/master/System.Web/ModelBinding/ModelStateDictionary.cs#L37-L41
About "can it be that 0 errors and IsValid == false": here's MVC source code from https://github.com/Microsoft/referencesource/blob/master/System.Web/ModelBinding/ModelStateDictionary.cs#L37-L41
public bool IsValid {
get {
return Values.All(modelState => modelState.Errors.Count == 0);
}
}
