SentimentConfig parameter of SentimentClassifier constructor has no effect now. It remains as a parameter for the back-compatibility.

var sentimentClassifier = new SentimentClassifier();
 
/// PositiveProbability method returns the probability of the positive sentiment.
var positiveProbability = sentimentClassifier.PositiveProbability("This is a new must-have thing.");
Console.WriteLine($"The probability of a positive sentiment is { positiveProbability }");
 
/// Classify method returns ClassificationResult object with the best class probability and name.
var response = sentimentClassifier.Classify("This is a new must-have thing.");
Console.WriteLine($"The best class name:{response.BestClassName}, probability: {response.BestClassProbability}");

Added a new taxonomy: Taxonomy.Sentiment3

Taxonomy.Sentiment3 categorize sentiments into Negative, Neutral or Positive classes and can be used with Classifier class

var classifier = new Classifier();
var response = classifier.Classify("This is a new must have thing.", taxonomy: Taxonomy.Sentiment3);
Console.WriteLine(response.BestClassName);
