  • Adhoc testing of .NET RIA Services

    Suddenly my Silverlight 3 application breaks during development process. Cause I have installed Visual Studio 2010 a few hours before, I was sure: must be something with 2010. After uninstall and reinstall SP1 everything worked fine, except .NET RIA services :-(

  • ASP.NET have left the track?

    I am a fan of ASP.NET. I have teached hundreds of peoples, written some books, have been MVP for that topic. But now I have doubts. Today I try to build a special kind of user navigation experience. I learn ASP.NET have stopped to grow since version 2.0. ASP.NET 2.0 is the most productive web (even UI ) development technology in the market. But today's needs have changed. For my site I need a Menu control which popup horizontal. Menu control is the same since 2.0 and can only vertical. Some tricks based on ASP.NET CSS friendly control adapters does not work cause the development of CSS adapters was stopped in early 2007 (or truly give over to community which is the same). My need is a second static tabbed main menu without dynamic popup. This can be set by MaximumDynamicDisplayLevels to 0. CSS Adapters ignore this setting so I cant use it.

  • Silverlight Twitter Client with authentication

    Its not easy to access a cross domain RSS feed. But it is nearly impossible to do same with authentication. HTTP Client stack and HTTP browser stack in Silverlight 3 and beyond does not support authentication. All tricks with manipulating HTTP header throw some not implemented exception.

  • Silverlight 3 Visual Studio 2008 Designer Preview

    Documentation says that Design Preview in Silverlight 3 Tools for Visual Studio 2008 is away. The preview with Silverlight 2 was only read only and sucks. OK is bad but no preview is even worse. When you right click a XAML file there is still context menu “view Designer”.

  • Silverlight 3 Beta to RTW changes

    It is very important that your applications are ready for Silverlight 3. If you have developed with the Beta bits you have to do a lot of changes to get ready for RTW. There exists a document changes.docx which I can not find at the moment. For that reason I decided to make a copy public on my private server.
