[IronPython] IronPython 2.6.1 for .NET 4.0 RC targeting Silverlight

[David Matson]

Jimmy,

I was using the DLLs from the .NET 2.0 release and that worked fine
albeit there are several warnings regarding types existing in both the
.NET and the IronPython assemblies. However, I tried to use an
ExpandoObject and now I get the error:

The type 'System.Dynamic.ExpandoObject' exists in both 'c:\Program
Files (x86)\Reference
Assemblies\Microsoft\Framework\.NETFramework\v4.0\Profile\Client\System.Core.dll'
and '\IronPythonDlls\Microsoft.Scripting.Core.dll'

When Silverlight 4 is considered the stable version, which is a subset of .NET 4, "IronPython for .NET 4.0" will contain binaries build against Silverlight 4. Note that those Silverlight binaries will run on Silverlight 4, they just aren't built against Silverlight 4, so any .NET 4.0 specific features (like "dynamic" interop) are not available, but normal app development works.
