Remarks
The generic overloads of the GetDocument<T>(String, GetDocumentOptions, CancellationToken) and GetDocumentAsync<T>(String, GetDocumentOptions, CancellationToken) methods support mapping of Azure Search field types to .NET types via the type parameter T. Note that all search field types except collections are nullable, so we recommend using nullable types for the properties of T. See GetDocumentAsync<T>(String, GetDocumentOptions, CancellationToken) for more information.
