It's been interesting looking at the reactions from around the blogosphere. With so many people playing telephone, I thought I'd collect a bunch of facts together in one place so that folks can get a clearer picture about what we're doing.

  1. The DLR requires the CLR. So this means that it only works with the Silverlight 1.1 Alpha that was released at MIX, and not the Silverlight 1.0 Beta.

  2. The source code for DLR, IronPython (and IronRuby when it is released) are being released under the Ms-PL. The Ms-PL is a BSD-style license.

  3. The DLR will also run on top of the desktop CLR V2.0, not just the Silverlight CLR. We have a generic hosting API that lets us retarget the DLR to run on top of arbitrary hosts. Silverlight is only one such host.

  4. The Silverlight 1.1 Alpha bits released at MIX include the DLR, IronPython and managed JScript.

  5. Silverlight lets you run compiled .NET code in the browser, not just Python and JScript code. Any assembly that has been compiled to target the Silverlight libraries should just work. So if you want to write code in C#, VB.NET or Boo to target Silverlight, knock yourself out.

  6. Our JScript implementation targets the ECMAScript 3.0 specification.

  7. We will implement four languages for the DLR: IronPython, IronRuby, JScript, and Visual Basic. As of this writing we are only releasing the source code for IronPython and IronRuby under the Ms-PL. We have not decided whether we will release the source code for either JScript or Visual Basic.

  8. Silverlight is targeted at browsers that run on the two most popular client operating systems: Windows and Mac OS X. Miguel de Icaza was quoted as saying that they will release a Mono+Linux implementation of Silverlight by the end of the year.

  9. Silverlight V1.1 will only target Intel Mac OS X machines.

Is there anything else that I missed?
