ML.NET Tutorial - Get started in 10 minutes

The ML.NET CLI has generated the trained model and code for you, so you can now use the model in .NET applications (for example, your SentimentModel console app) by following these steps:

1. In the command line, navigate to the consumeModelApp directory.
   Command promptCopy

   cd SentimentModel

2. Open the Program.cs in any code editor and inspect the code. The code should look similar to the following:

   Program.csCopy

   using System;
   
   namespace SentimentModel.ConsoleApp
   {
       class Program
       {
           static void Main(string[] args)
           {
               // Add input data
               SentimentModel.ModelInput sampleData = new SentimentModel.ModelInput()
               {
                 Col0 = @"Wow... Loved this place."
               };
   
               // Make a single prediction on the sample data and print results
               var predictionResult = SentimentModel.Predict(sampleData);
   
               Console.WriteLine("Using model to make single prediction -- Comparing actual Col1 with predicted Col1 from sample data...\n\n");
   
   
               Console.WriteLine($"Col0: @{"Wow... Loved this place."}");
               Console.WriteLine($"Col1: {1F}");
   
   
               Console.WriteLine($"\n\nPredicted Col1: {predictionResult.PredictedLabel}\n\n");
               Console.WriteLine("=============== End of process, hit any key to finish ===============");
               Console.ReadKey();
           }
       }
   }

3. Run your SentimentModel.ConsoleApp. You can do this by running the following command in the terminal (make sure you are in the SentimentModel directory):

   Command promptCopy

   dotnet run

   The output should look something like this:

   Command promptCopy

   Using model to make single prediction -- Comparing actual Col1 with predicted Col1 from sample data...
   
   
   Col0: Wow... Loved this place.
   Col1: 1
