Automapper Mapping Exception with Model and private Properties

Question

I am using AutoMapper to map two objects. ViewModel and Model, where ViewModel Implements InotifyPropertyChanged. How can i map Model to ViewModel. Below is my scenario,

1. Model

   public class Model
   {
       public string ResultType { get; set; }
   }
   

2. ViewModel

   public class ViewModel : Screen
   {
       private string _resultType;
   
       public string ResultType
       {
           get { return _resultType; }
           set
           {
               _resultType = value;
               NotifyOfPropertyChange(() => ResultType);
           }
       }
   }
   

3. Create Map implementation

   mapper.CreateMap<Model, ViewModel>();
   mapper.CreateMap<ViewModel, Model>();
   mapper.AssertConfigurationIsValid();
   
   var test1 = new Model() {ResultType = "Test Result"};
   var s1 = mapper.Map<ViewModel>(test1);
   

I get AutoMapper Mapping Exception when i call mapper.Map.

Missing type map configuration or unsupported mapping. Mapping types: Model-> ViewModel Support.Model -> Support.ViewModel

Like mentioned, you aren't actually showing any mapping code. Based on what you've provided, do something like this:

var config = new MapperConfiguration(cfg => {
    cfg.CreateMap<Model, ViewModel>();
});

Here's a working example: https://dotnetfiddle.net/YnZ1nw
