I downloaded Silverlight 1.1 Alpha and poked around until I found out where the .NET stuff lives. Here’s what’s in the bundle:
$ cd /Library/Internet\ Plug-Ins/Silverlight.plugin/Contents/MacOS/ $ ls CoreCLR.bundle System.Core.dll IronPython.Modules.dll System.SilverLight.dll IronPython.dll System.Xml.Core.dll Microsoft.JScript.Compiler.dll System.dll Microsoft.JScript.Runtime.dll agclr.dll Microsoft.Scripting.SilverLight.dll agcore Microsoft.Scripting.Vestigial.dll slr.dll Microsoft.Scripting.dll slr.dll.managed_manifest Microsoft.VisualBasic.dll
And check out what those DLLs are made of:
$ file System.dll System.dll: MS Windows PE 32-bit Intel 80386 console DLL
But what’s this thing? Man, that’s big!
$ file agcore agcore: Mach-O universal binary with 2 architectures agcore (for architecture i386): Mach-O bundle i386 agcore (for architecture ppc): Mach-O bundle ppc $ ls -l agcore -rwxr-xr-x 1 502 admin 16083600 Apr 26 03:16 agcore
So how much of those DLLs are managed code? Do they contain Win32 code, and does agcore have some magic in it for bootstrapping Win32 code?
