1. App Peripherals CAN BILGIN, Authority Partners Inc.

3. Connectivity
One Windows. Tens of device types and gadgets. Cloud, web, home, car, tv, sound system… Multiple Connection options and protocols.

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

5. Indigo

6. UWP applications can now utilize WCF services
WCF is BACK!

7. 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

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

10. Web

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

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

13. 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.

14. Extremely crucial for IoT implementations.
SignAL-R

15. Signal-R

17. Sockets

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

19. 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); }

20. 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);

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

22. Bluetooth

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

24. Bluetooth Stack
Completely merged with WinRT GATT / LE RFCOMM

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

27. 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.

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

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

31. Wi-Fi

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

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

34. 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); } }

35. 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”);

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

37. 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();

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

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

42. AllJoyn

43. Applications can utilize AllJoyn Producer/Consumer Model
