1 .NET Micro Framework Devices Profile For Web Services DPWS Jim Mateer Program Manager.NET Micro Framework

2 .NET Micro Framework Microsoft s latest offering for embedded development Small, resource constrained devices Underlying OS is not necessary Managed execution environment Visual Studio development environment Extensible hardware emulator

3 Extending the Microsoft Embedded Story Visual Studio + Managed Code Wearable Devices Sensor Nodes Windows Mobile Smartphone Windows Mobile Pocket PC Phone Retail Point-of-Sale Security Auxiliary Displays Windows Automotive Windows-based Terminals Portable Media Center Medical Devices Building Automation VoIP Phones Health Monitoring Mobile Handhelds Set-top Boxes Entertainment Devices Remote Controls Gateways.NET Micro Framework Windows CE Increasing Functionality Decreasing Size Windows XP Embedded

4 Advantages of the.net Micro Framework Visual Studio Development Environment.NET Managed development and execution No native or core development required Small footprint

5 .NET Micro Framework V2.0 V1 was an internal build V2.0 was released at Embedded World, Germany 02/2007 Service Pack 1 released 9/18/2007 at ESC East

6 Service Pack 1 TFFont.EXE Improved deployment feedback Improved sockets Firmware and Application IP protection Extended flash management tool (MFDeploy) Greatly expanded documentation Customer reported bug fixes

7 Architecture

8 Microsoft Web Services Architecture Windows Communication Foundation (WCF) The next-generation Microsoft programming platform and runtime system for building, configuring, and deploying network-distributed services. Network Connected Devices (NCD) A set of 4 technologies that enable virtually connected devices to appear as if they were physically connected Devices Profile for Web Services (DPWS) Enables basic interoperability between IP-capable Devices and Web services..net Micro Framework DPWS (MF-DPWS) A DPWS stack developed specifically for the.net Micro Framework

9 DPWS Service Hosting Examples of devices hosting one or more services Fax/Printer/Scanner A device can host multiple services. Each service operates as a separate, individual entity with its own endpoints Projector The Printer and Projector device profiles are included in Windows Vista Thermostat Any device running the.net Micro Framework can host or consume web services. All that is needed is a Device Profile for that device Smart CoffeeMaker MF-DPWS provides the DPWS stack and necessary base classes to enable creating Device Profiles

10 DPWS Clients Examples of devices as clients PDA SmartPhone MP3 Player Remote controls Examples of things client devices can do Subscribing to Web Services, such as a Stock Ticker Subscribing to traffic flow services Subscribing to a home event notification service Subscribe to a home music delivery service Initiate service actions Remotely control devices

11 MF-DPWS Hybrid Devices Hybrid Devices Intelligent power monitoring Subscribing to power company service to determine best rates (Client) Providing rate information to smart appliances (Service) Navigation System Subscribing to local services (Client) Gas prices Restaurant seating availability Traffic conditions Providing location information (Service) Current location Destination (if a route is active) Speed and Direction

12 MF-DPWS Stack (1) What is included Most of everything from the DPWS 2/2004 specification Discovery Probe and Match Metadata Exchange Eventing Hello Bye Subscriptions Attachments MTOM

13 MF-DPWS Stack (2) What is not included WS-Policy is not supported WS-Security is not supported DateTime types not supported for Subscription Duration/Renewal IPv6

14 MF-DPWS A Typical operation

15 MF-DPWS Stack Classes MFDpwsStack.DLL All Managed Code (C#) Base services and extensibility features Provides tools to develop custom DPWS profiles HTTP and UDP Transport Services Service Endpoint classes SOAP message parsers Service dispatchers MTOM processor XML Services

16 MF-DPWS Client Classes MFDpwsClient.DLL Classes provide boilerplate DPWS/WS* Services Client specific Discovery Eventing (Subscribing) Application developers derive custom classes from DPWS client classes Used to create device specific client implementations

17 MF-DPWS Device Classes MFDpwsDevice.DLL Frame work for device specific implementations Base methods called by MF-DPWS services Dispatching Requests Dispatching Events Stores actions and events Used by application developers to develop device specific functionality

18 MF-DPWS Availability Beta program available now Contact for details.net Micro Framework DPWS Code generation tool under development (ETA ~Q1/2008) MF specific version of Svcutil.EXE Generates WSDL from a Service Generate an MF-Client from a WSDL Generate an MF-Service stub from a WSDL Currently only supported on Digi ConnectME device Other platforms support expected 12/2007
