  • Fixing Data Binding Problems in WPF/Silverlight

    The data binding in WPF and Silverlight is amazing in all regards. Its power and flexibility are beyond compare. Unfortunately its resistance to traditional debugging techniques is equally impressive for the wrong reasons. There is no way to really step through the data binding process, but we collected some other techniques that developers may find useful.

  • Three Hotfixes for WPF Memory Leaks

    Windows Presentation Foundation is quickly becoming well known for the ease in which memory leaks are introduced. Most of these leaks seem to come from the use or misuse of weak references, upon which WPF’s data binding technology is based. In the recent set of hotfixes many of these leaks are fixed.

  • Karl Shifflett Shows How to make VS 2010’s Binding Builder Actually Work

    Visual Studio 2010 comes with a feature they call the “Binding Builder”. This tool, launched from the properties pane, helps developers quickly construct XAML bindings for WPF and Silverlight. But without some help, it doesn’t work when the data context is only set at runtime. Karl Shifflett shows how to work around this using design-time markup extensions.

  • Prism Prevents One Incomplete Feature from Derailing an Entire Release

    Having modular code does not help when applications still have to be deployed in an all-or-nothing fashion. Prism addresses this by allowing you do deploy a WPF or Silverlight shell to the users separately from any specific functionality. Individual features are released out-of-band as modules that may be stored locally, on a corporate file share, or served up by a web site.

  • PyBinding: Python Scripting for XAML

    WPF developers often find themselves with an unappetizing choice. They have to either pollute their code-behind files with special case logic or create value converter classes, most of which will only be used once. PyBinding offers a third option, embedding small scripts right inside the XAML.

  • .NET 4.0 Brings XAML 2009, but Not for WPF Users

    At PDC 2009, Michael Shim and Rob Relyea presented Microsoft’s plans for the future of XAML. Long term, they plan on unifying the various XAML languages and parsers, but for now developers will only get XAML 2009 for non-UI technologies like Workflow Foundation. The new parser, on the other hand, will bring new functionality to everyone who needs to analyze, manipulate, or generate XAML.

While we recommend developers read all of it, we offer you a summary of the major ones that impact line-of-business developers.

    WPF 4.0 will be adding new controls, Pixel Shader 3.0, and a completely rewritten text rendering pipeline. These and other features will find their way into Visual Studio 2010, expected early next year.

  • Serious Memory Leaks Plague WPF

    WPF, also known as Windows Presentation Foundation, represents the future of UI on the Windows platform. And if Microsoft has its way, its younger sibling Silerlight will take over the web and mobile markets. But like any new technology, it has some issues to work through including some rather serious memory leaks.
