Connecting People Devices Connectivity on and among UWP devices is crucial!

Indigo

UWP applications can now utilize WCF services WCF is BACK!

Evolving WCF Released in November 2006 With .NET 3.0 9/12/2017 5:10 PM Evolving WCF Released in November 2006 With .NET 3.0 Go to technology in Windows App Fabric in 2010 Still used as the underlying tech for Service Fabric in 2016 Removed from Windows 8.1 Phone but back on UWP Part of .NET Core © 2014 Microsoft Corporation.

Revamped WCF Stack Supported Bindings Client Channels & Features BasicHttpBinding NetTcpBinding NetHttpBinding Session Streams Duplex Channels

Web

HttpClient Revisited .NET client & WinRT version merged into one. Supports and, if possible, uses HTTP/2 Up to 100% faster. Complete A-synchronicity.

Web Sockets Full-duplex single socket. Used for real-time data and messaging. Regarded as a web technology MessageWebSocket and StreamWebSocket.

UWP Socket Scenarios MessageWebSocket StreamWebSocket Suitable for typical scenarios where messages are not extremely large. Suitable for scenarios in which large files (such as photos or videos) are being transferred. Enables notification that an entire WebSocket message has been received. Allows sections of a message to be read with each read operation. Supports both UTF-8 and binary messages Supports only binary messages. Similar to a UDP or datagram socket. Similar to a TCP or stream socket.

Extremely crucial for IoT implementations. SignAL-R

Signal-R

Sockets

System.Net.Sockets Optimized Performance (Batched Sends). WinSock, StreamSocket and Secure Channels… SocketActivityTrigger and SocketBroker.

Batched Send // Send a set of packets inefficiently, one packet at a time. IList<IBuffer> packetsToSend = PreparePackets(); var outputStream = stream.OutputStream; foreach (IBuffer packet in packetsToSend) { // Incurs kernel transition overhead for each packet await outputStream.WriteAsync(packet); }

Batched Send // This way enables the system to do batched sends IList<IBuffer> packetsToSend = PreparePackets(); var outputStream = stream.OutputStream; int i = 0; Task[] pendingTasks = new Task[packetsToSend.Count]; foreach (IBuffer packet in packetsToSend) { // track all pending writes as tasks, pendingTasks[i++] = outputStream.WriteAsync(packet).AsTask(); } await Task.WaitAll(pendingTasks);

Background Sockets Create a SocketActivityTrigger Register a background task. Open the socket and/or socket listener TransferOwnership of the socket.

Bluetooth

NEW Bluetooth Profiles New Bluetooth APIs available for UWP NEW Bluetooth Profiles

Bluetooth Stack Completely merged with WinRT GATT / LE RFCOMM

Bluetooth Stack Completely merged with WinRT Beacon/Advertisement Low-Energy Profile Improvements

Windows 10 APIs Windows.Devices.Bluetooth.Advertisement Windows.Devices.Bluetooth.Background Simple but powerful advertising functionality Watcher – receive advertisements. Publisher – limited broadcast functionality Trigger Implementations for RFCOMM, GATT and Advertisement. Windows.ApplicationModel.Background Power efficient watcher.

Beacon/Advertisement Consumer: Configure watcher with filters Attach event handlers Start the watcher

Beacon/Advertisement Publisher: Configure publisher with payload Start publisher Received Signal Strength Indication (RSSI) Header MAC Payload

Wi-Fi

Applications can take more out of WI-FI Wi-Fi SCENARIOS

Wi-Fi Control Use Radio utility class to control Wi-Fi Radio. Use WiFiAdapter class to utilize adapters. Discover and Connect to Networks.

Wi-Fi Control // Request access to set the radio state // must be called at least once from the UI thread await Radio.RequestAccessAsync(); // Turn on Wi-Fi radios var radios = await Radio.GetRadiosAsync(); foreach (var radio in radios) { if (radio.Kind == RadioKind.WiFi) { await radio.SetStateAsync(RadioState.On); } }

Wi-Fi Control var access = await WiFiAdapter.RequestAccessAsync(); if (access == WiFiAccessStatus.Allowed) { var result = await Windows.Devices.Enumeration.DeviceInformation. FindAllAsync(WiFiAdapter.GetDeviceSelector()); if (result.Count >= 1) firstAdapter = await WiFiAdapter.FromIdAsync(result[0].Id); } else NotifyUser(“No WiFi Adapters detected on this machine”);

Wi-Fi Direct Services App Specific Communication Advertiser/Connector Model Needs to be supported by hardware Bi-Directional: Seeking & Advertising

Wi-Fi Direct Services // Create an Advertisement Publisher var publisher = new WiFiDirectAdvertisementPublisher(); // Turn on Listen state publisher.Advertisement.ListenStateDiscoverability = WiFiDirectAdvertisementListenStateDiscoverability.Normal; // Register for connection requests var listener = new WiFiDirectConnectionListener(); listener.ConnectionRequested += OnConnectionRequested; // Start the advertiser publisher.Start();

Teethering Start a Mobile Hotspot on the Device. Was only available for Mobile Operators.

Teethering – Initialize Manager NetworkOperatorTetheringManager tetheringManager = null; ConnectionProfile profile = NetworkInformation.GetInternetConnectionProfile(); if (profile != null && profile.IsWwanConnectionProfile) { tetheringManager = NetworkOperatorTetheringManager .CreateFromConnectionProfile(profile); }
