Yes, Michael is right, you can use Silverlight 4 features (like RichTextBox)
from IronPython 2.6. The "catch" is that any features in IronPython 2.6 that
are specific to .NET 4.0 cannot be used in Silverlight 4; the major one is
the DLR integration with C#, so C# code hosting IronPython in Silverlight
can't use the "dynamic" keyword to make accessing variables defined in
IronPython code easier.

Upgrading to IronPython 2.7 Alpha 1  for Silverlight 4 development is
definitely preferred over staying on IronPython 2.6. If there are any bugs
in IronPython 2.7 Alpha 1 that block you from doing this, please report
them.
