// using Microsoft.Toolkit.Uwp.Services.MicrosoftTranslator;

await TranslatorService.Instance.InitializeAsync("<translator service key");

// Retrieves codes and friendly names for the languages available for text translation.
var languages = await TranslatorService.Instance.GetLanguageNamesAsync("en");

// Detects the language of a text.
var detectResult = await TranslatorService.Instance.DetectLanguageWithResponseAsync("Hello everyone!");
var detectedLanguage = detectResult.Language;
var detectedLanguageConfidence = detectResult.Score;

// Translates the text to Italian.
var translationResult = await TranslatorService.Instance.TranslateWithResponseAsync("Hello everyone!", "it");
var translatedText = translationResult.Translation.Text;
' Imports Microsoft.Toolkit.Uwp.Services.MicrosoftTranslator

Await TranslatorService.Instance.InitializeAsync("<translator service key")

' Retrieves codes and friendly names for the languages available for text translation.
Dim languages = Await TranslatorService.Instance.GetLanguageNamesAsync("en")
