.Net comes to Web
Today microsoft announced that Silverlight will have .Net based APIs. This means there is a small CLR runtime that will go cross platform to Mac. This will enable developers to manipulate great graphics capability that Silverlight provides using advanced languages like C#. This also means familiar tools for building Windows application such as Visual Studio can be used to build next generation cutting edge internet application.
As I type this post, Ray Ozzie just announced that "silverlight will bring .Net to universal web".
