• Visual Studio Team System Unit testing a form...

  We're trying to unit test the main form of our application. Things like instantiating the form, checking for the default controls, invoking something that creates a new panel, checking for focus inside this new panel... all these things work great.

• Visual Studio 2008 (Pre-release) extension properties

  When the first Linq preview was released, there was talk of allowing extension properties along with extension methods. At the time, I couldnt see a good reason for having them, but having read "First-class relationships in an object-oriented language" I can now absolutely see a use for them. At least, a very nice syntactic sugar type of use. I know the details on the next Linq release have been short on the ground, but would some Linq ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Why is managed DirectX using classes over interfaces?

  Hi, I'm wondering if anyone can answer the above question Why are method calls going over classes rather than interfaces I would have thought that each managed assembly would still use interfaces from class factories rather than using explicit classes in a namespace. Doing so would mean that your application would not break when new versions are released. E.g. ILight9 light = new Light9 (); light.LightType = LightType .D ...Show All
