[IronPython] System, Version 2.0.5.0

[Srivatsn Narayanan]

One thing we are doing that will help here is starting from beta3 the ironpython codeplex sources will have the silverlight sources (including Chiron) and Ironpython.sln will be configured the way Ivan mentioned in the IronRuby alias so that a msbuild /p:Configuration="Release" builds the desktop version of ipy/dlr and msbuild /p:Configuration="Silverlight Release" builds the silverlight version.

Silverlight is not a host, it's a platform, with unique compilers and libraries. The .NET framework shipped with Silverlight is not the same as what's on the desktop, though meant to look the same by having a similar API. Plus, there are "platform" specific features of each, like security levels and the file system on the Desktop and HtmlBridge and isolated storage on Silverlight.

Point being, to use something on a specific platform, it must be built for that platform. The source code may be the same for each, but that's a detail of the implementation. If you look at your Silverlight installation location, there is mscorlib.dll, System.Windows.dll, etc ... all have "equivalent" Desktop versions, but they are definitely not interchangeable.

This is what it's like living in a compiled world =P

Make sense?
