Empty xml description

[kurnakovv]

Describe the bug
Empty description when you try to view any function in Visual Studio (not sure about other IDEs), but the XML docs exist.

To Reproduce

1. Call any function (for example ITranslator.TranslateTextAsync)
2. Hover your mouse over any function to see a xml description
3. See nothing

Expected behavior
Xml docs: summary, params, etc

Screenshots or sample code

var translator = new Translator("my-api-key");
var result = await translator.TranslateTextAsync(
    text: "Hi, how do you do?",
    sourceLanguageCode: "EN",
    targetLanguageCode: "PL"
);

Additional context
This happens because the code does not have the GenerateDocumentationFile property. Info about this property here
