(All work done with VS2010 RC and matching IronRuby build (v0.9.40, 07-Feb-10)).

I have a C# assembly that implements a dynamic object. When I try to use this 
object from Ruby I get the error:

>>> r.StdUnitCost
System.Core:0:in `BindCore': unbound variable: Param_0 (TypeError)
        from (ir):1

This usage works fine from a test C# 4.0 app using the 'dynamic' keyword.

I suspect that the issue is related to the version of the DLR in use -- there 
are a number of 'InvalidOperationExceptions' being thrown from the 
Microsoft.Dynamic.dll and I believe this is no longer a shipping assembly with 
.NET 4?

Is there a (simple) work around for this?

Thanks,
