  • Understanding ASP.NET AJAX Web Service Proxies

    Proxy code plays an important role in sending and receiving messages to and from Web Services.  If you've worked with Web Services before in .NET, Java or other programming frameworks then chances are you used a client-side proxy to call a Web Service.  With .NET, proxies are generated using wsdl.exe or Visual Studio's Add Web Reference menu option.  ASP.NET AJAX proxies aren't created this way, however.  In fact, they're even easier to create compared to C# or VB.NET Web Service proxies. An ASP.NET AJAX Web Service proxy is created by using the Services property of the ScriptManager control:

  • WPF/E Pad

    Microsoft's Mike Harsh just released an updated version of his WPF/E Pad that makes it easy to quickly test out XAML using the WPF/E viewer.  Pretty cool stuff!  Since I'm a big fan of XML I'm really excited about what WPF/E offers.

  • .NET Distributed Application Development

    I'm teaching Microsoft's .NET Distributed Application Development course this week in Phoenix and wanted to get some sample code I put together posted for everyone that is attending (and anyone else that is interested).  The code demonstrates asynchronous Web Services calls, MSMQ fundamentals, remoting through code and remoting through configuration files, using delegates with remoting, WSE 3 features, plus more. 

  • Video: Debugging ASP.NET AJAX Applications with VS.NET 2005

    Debugging is a key skill that every developer has to learn to become productive. However, how do you debug ASP.NET AJAX applications and client-side JavaScript? In this video tutorial I walk through a few required steps to enable debugging and show how to use tools such as the Script Explorer to simplify the process. It's important to note that many of the features shown in the video can also be used with the Visual Web Developer Express.

  • Video: Calling Web Services using ASP.NET AJAX and JavaScript

    ASP.NET AJAX provides several different ways to call Web Services including JavaScript, XML Script and the AutoCompleteExtender. In this video tutorial you'll see how to call Web Services using JavaScript. Topics covered include creating a Web Service, applying the ScriptService attribute, creating a client-side JavaScript proxy and calling a Web Service using JavaScript and callbacks.
