Yes, I can repro it using both IronPython binaries built against SL3 and SL4; it appears that the RichTextBox.ctor() fails to be called via reflection. We call via reflection in the interpreter first as an optimization, and then generate code to do the call; though it looks like both paths are failing. I’m looking into this … installing windbg on my new machine at the moment =P >>> The person who started this thread reported not being able to reference the >>> assemblies. Oh, I thought they were trying to add references to the .NET 4.0 built assemblies in a Silverlight project, which absolutely doesn’t work; you need to use a build for Silverlight.

(Try Python uses IronPython that was built against Silverlight 2 - but dynamically uses some Silverlight 3 APIs if they are available.) As Silverlight 4 includes a different version of the CLR - and not just different API sets - I guess it particularly makes a difference if you are compiling C# code that works with IronPython. Odd and annoying that it won't even add references to earlier versions though. Does *everything* need to be specially compiled to be used with .NET 4? The *current* Silverlight builds can use SL4 features; like webcam, etc. This is because IronPython calls .NET APIs dynamically. However, since the Silverlight 2 builds don't statically depend on any of the new APIs in the Silverlight 4, any CLR4 features that the compilers/libraries usually depend on in .NET 4 aren't available in Silverlight 4; that's what the Silverlight 4 build will do for you. Did you see the report of my problem with the RichTextBox with IronPython 2.6.1 RC. Do you see the same problem? With regard to adding references to assemblies; as long as the same APIs exist in both versions of Silverlight, it will work in both, regardless of which compiler you use. It's the same situation with different .NET versions. Did I miss something where someone reported not being able to do this? The person who started this thread reported not being able to reference the assemblies.
