Juval Lowy - Introducing the .NET Service Bus

martinesmann — Tue, 24 Nov 2009 10:10:00 GMT

The .NET services bus is part of the new Microsoft Cloud Computing Windows Azure initiative, and arguably, it is the most accessible, ready to use, powerful, and needed piece. The service bus allows clients to connects to services across any machine, network, firewall, NAT, routers, load balancers, virtualization, IP and DNS as if they were part of the same local network, and doing all that without compromising on the programming model or security. The service bus also supports callbacks, event publishing, authentication and authorization and doing all that in a WCF-friendly manner. This session will present the service bus programming model, how to configure and administer service bus solutions, working with the dedicated relay bindings including the available communication modes, relying on authentication in the cloud for local services and the various authentication options, and how to provide for end-to-end security through the relay service. You will also see some advanced WCF programming techniques, original helper classes, productivity-enhancing utilities and tools, as well as discussion of design best practices and pitfalls.

Peer to Peer Series Part 6: Introduction to PeerChannel

Jeff Brand — Fri, 06 Nov 2009 16:32:00 GMT

In Part 6 of the Peer to Peer Series, I set the stage for learning how to use WCF's PeerChannel. After a simple overview of PeerChannel, I show a sample application that uses PeerChannel to play buzzword bingo. The focus of this installment is to give an understanding of some of the key considerations one must think about dealing with the message broadcasts that comprise a PeerChannel application.

The next few installments will focus extensively on building peer applications using PeerChannel.

Important Note: I errored in splicing my video together. The demo is actually later in the video and not immediately after the demo transition slide. Everything is there, just not in the right order. I'll try and get an edited version up later.

Peer to Peer Series Part 5: Direct Connect Peers via WCF

Jeff Brand — Thu, 08 Oct 2009 17:51:00 GMT

In Part 5 of the Peer to Peer Series, I show a sample application that uses PNRP to connect a client application to a server application using WCF and PNRP Peer Host Names. The details of the actual WCF Service implementation. Instead, I will focus on those areas of leveraging PNRP to establish connections via WCF.

The video will show a sample application that is comprised of a client and a server application. You could use a more “peer-to-peer” duplex-style of communication, but the client-server arrangement makes the two key parts of establishing a WCF connection easier to explain.

When hosting a WCF service, the key code from the IntelServiceHost.cs file is shown below:

this.PeerRegistration.Start(peerClassifier, port);

Uri tcpUri = new Uri(string.Format("net.tcp://{0}:{1}/IntelService", this.PeerRegistration.PeerUri, port));

_serviceHost = new ServiceHost(service, tcpUri);

NetTcpBinding tcpBinding = new NetTcpBinding(SecurityMode.None);

_serviceHost.AddServiceEndpoint(typeof(IIntelService), tcpBinding, "");

The PeerRegistration property exposes a wrapper class around the PNRP API. The Start method registers the application with a given peer classifier and port as an unsecure peer name in the Global PNRP Cloud. The PeerUri property passes back the peerhostname. That uri is used to setup a new Uri, along with the port, that is then used to configure the ServiceHost using a NetTcpBinding. Some of this could have been configured in the application’s config file, but I put it all here so you can see how the different parts relate.

The client side of the equation is even easier (found in the IntelClient.cs file):

PeerNameResult peerRecord = PeerResolution.ResolveHostName(hostPeerName);

System.ServiceModel.Channels.Binding netBinding = new NetTcpBinding(SecurityMode.None);

EndpointAddress endpointAddress = new EndpointAddress(string.Format("net.tcp://{0}:{1}/IntelService", peerRecord.Uri, peerRecord.Port));

IntelServiceProxy = new IntelProxy(netBinding, endpointAddress);

The PeerResolution class is another wrapper around the PNRP API, this time providing resolving a given unsecure peer name in the Global PNRP cloud. It returns an object containing the remote peer’s peerhostname and port. The rest of the code is just setting up the client side of the WCF connection.

Web Application Toolkit: REST Services

Jonathan Carter — Thu, 24 Sep 2009 18:02:00 GMT

This Web Application Toolkit shows how to easily add REST service interfaces for an existing Web application. The Web Application Toolkit includes a sample of REST services based on a fictitious online auction site. It exposes an API using REST services built with the Windows Communication Foundation that can consumed by client applications. Two sample client applications are included, one using simple ASP.NET pages to consume the REST service and show a list of ending auctions, and a second Web application using AJAX to asynchronously invoke the REST service to show a list of most viewed auctions. The Web Application Toolkit also includes a custom project template for Visual Studio to make it easier to build new REST Services.

Juval Lowy – The EnergyNet and the next Killer App

Robert Hess — Wed, 23 Sep 2009 22:06:00 GMT

Many people love to speculate on what the next Killer App might be. Juval Lowy will use his ideal killer app as the basis of his upcoming workshop at PDC09 on November 16th. He’d like to think that the EnergyNet (yeah… I called it “energyweb” in my intro) might provide such a cohesive blending of commercial and residential energy use, the devices which consume that energy and the resources that provide it, that this will become an important piece of our daily lives. It will save money, save energy, and perhaps even save the planet.

In his workshop, he is going to illustrate how the notion of an EnergyNet is made possible through technologies such as Windows Communication Foundation and the .NET Service Bus. I’ve asked special correspondent Bruno Terkaly to interview Juval and get some details on what you’ll learn about in this workshop.

You can get more details about this workshop here:

Software in the Energy Economy

You can get some more details on the EnergyNet in an interview that Juval did for ARCast.TV on Channel9 here:

Navigating through the hypes, Software architectures and patterns to help avoiding your projects to crash. (Dutch)

Matthijs Hoekstra — Fri, 04 Sep 2009 13:01:00 GMT

When it comes to .Net software development, more and more frameworks enter the market. Both from Microsoft and in open source. Just think of all the very useful frameworks, such as ASP.NET MVC, Castle, WF, Entity Framework, Unity, Linq2SQL, ADO.NET Data Services, WCF, nHibernate, Spring.NET, CSLA, NUnit, Enterprise Library or ADF. Once a project chooses to apply one or more frameworks, trouble begins. What if you require additional features that aren’t implemented in the framework? What if you decide that another framework would have been better and want to switch halfway your project? What if the author of your favorite open source framework suddenly stops developing? What if the framework contains bugs or omissions? And what if a new version of the framework is released that is implemented totally different? These and many more everyday problems will cause your project to come to a halt, or at least make you perform serious refactoring. During this highly interactive talk Sander Hoogendoorn, principal technology officer at Capgemini, chief architect of Capgemini’s agile Accelerated Delivery Platform, and member of Microsoft’s Visual Studio Advisory Board, will demonstrate pragmatic software architectures and patterns that will help your projects to stay away from framework problems, and how to keep your code independent of framework choices. In his well known slightly ironic style Sander will present different models of layered architectures, and explain and use bridge patterns, managers, dependency injection, descriptors, and layer super-types. Of course, the speaker will illustrate these insightful patterns with lots of demo’s and (bad) code examples using blocks from Microsoft’s Enterprise Library, nHibernate, Log4Net, and the Entity Framework. Delegates will benefit from this talk by learning how to improve the structure and quality of their software architecture and code, and how to avoid the pitfalls of applying frameworks to .Net software development.

Deze video is opgenomen tijdens de DevDays in Den Haag in juni 2009. DevDays is het grootste evenement op het vlak van softwareontwikkeling en -architectuur in Nederland. Duizenden development professionals bezoeken dit jaarlijkse evenement om in twee dagen weer volledig op de hoogte te zijn van alle ontwikkelingen op hun vakgebied.

NZsynth Building a Clickable Mosaic with DeepZoom and Silverlight 2

Nigel — Sun, 17 May 2009 20:11:00 GMT

It started as a conversation about "crowd sourcing" images that people have already tagged as New Zealand to construct a demo from our shipping Silverlight 2 technology. I spent 3 days building a "demo-ware" prototype and presented it during a keynote slot at WEB09.

Following that we held a Silverlight 3 camp over 3 1/2 days. At the camp Tim (a devloper from Wellington) improved my original prototype to make the image tiles clickable. I then took Tims work and adapted it to make a version two of my original design.

endpoint.tv - Service Discovery with WCF

Ron Jacobs — Thu, 14 May 2009 15:51:00 GMT

WCF in .NET 4 includes an implementation of the WS-Discovery protocol. Sounds exciting right? Actually it is very cool because it allows you to build applications and services that can discover other services using UDP multicast messages or via a discovery proxy. In this episode I'll walk through the Service Discovery lab where we build a messenger style application I call "ChatWOW". In this lab you will see how to make your service discoverable and how you can discover other services. Later when Beta 1 is released, you can try it yourself.

Update: The WCF/WF4 Training Kit is now live at http://code.msdn.microsoft.com/wcfwf4 so you can try it yourself.

MS Virtual Labs: Connected Applications with WCF and WF

joelercoaster — Mon, 04 May 2009 22:41:00 GMT

Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF) are relatively new technologies, having only been officially released with .NET 3.0 in November 2006. Despite this, each technology has received some significant updates for Visual Studio 2008. For WCF, the most visible update is the new tooling that enables developers to be more productive in creating and testing services. For WF, many of the improvements revolve around integration with WCF.

The purpose of this demo/lab is to show the new tooling for WCF and WCF/WF Integration. The demo covers the following topics:

• Windows Communication Foundation Test Server & Client
• Building a Workflow Service.
