// Initialize streaming call, retrieving the stream object
using FeatureOnlineStoreServiceClient.StreamingFetchFeatureValuesStream response = featureOnlineStoreServiceClient.StreamingFetchFeatureValues();

// Sending requests and retrieving responses can be arbitrarily interleaved
// Exact sequence will depend on client/server behavior

// Create task to do something with responses from server
Task responseHandlerTask = Task.Run(async () =>
{
    // Note that C# 8 code can use await foreach
    AsyncResponseStream<StreamingFetchFeatureValuesResponse> responseStream = response.GetResponseStream();
    while (await responseStream.MoveNextAsync())
    {
        StreamingFetchFeatureValuesResponse responseItem = responseStream.Current;
        // Do something with streamed response
    }
    // The response stream has completed
});

// Send requests to the server
bool done = false;
while (!done)
{
    // Initialize a request
    StreamingFetchFeatureValuesRequest request = new StreamingFetchFeatureValuesRequest
    {
        FeatureViewAsFeatureViewName = FeatureViewName.FromProjectLocationFeatureOnlineStoreFeatureView("[PROJECT]", "[LOCATION]", "[FEATURE_ONLINE_STORE]", "[FEATURE_VIEW]"),
        DataKeys =
        {
            new FeatureViewDataKey(),
        },
        DataFormat = FeatureViewDataFormat.Unspecified,
    };
    // Stream a request to the server
    await response.WriteAsync(request);
    // Set "done" to true when sending requests is complete
}

// Complete writing requests to the stream
await response.WriteCompleteAsync();
// Await the response handler
// This will complete once all server responses have been processed
await responseHandlerTask;
