What is the correct way to create custom model binders in MVC6?

Question

I\'m trying to follow the steps in this article using a vNext project and mvc 6. I\'ve been reading through the code here but still a little unsure how to implement this.

Answer 1

I have made a blog post that contains sample of trimming strings automatically in the model.

Blog post is here http://hotzblog.com/asp-net-vnext-defaultmodelbinder-and-automatic-viewmodel-string-trim/

I noticed that adding directly to model binders won't work totally, because model binders are used in order. You will have to first remove the original model binder

  services.AddMvc().Configure(options =>
  {
       // Replace MutableObjectModelBinder with extended Trimmer version
       IModelBinder originalBinder = options.ModelBinders.FirstOrDefault(x=>x.GetType() == typeof(MutableObjectModelBinder));
       int binderIndex = options.ModelBinders.IndexOf(originalBinder);
       options.ModelBinders.Remove(originalBinder);
       options.ModelBinders.Insert(binderIndex, new TrimmingModelBinder());
   });
