Maximum .NET version for Coldfusion 8 interop?

Question

I am modifying some CF8 code that uses the cfobject tag to do interop with .NET. Currently, it's targeting .NET 2.0 assemblies. Without upgrading CF, is there a way to get it to interoperate with higher versions of .NET (e. g. v4.0)? What, if anything, will I have to do?

(From the comments ...)

JNBridge is bundled with CF and used for .NET interop. AFAIK, support for v4.0 was not added until CF 9.0.1. The most definitive reference I could find on this was the JNBridge docs ie cf_root\jnbridge:

• ColdFusion 8 uses JNBridgePro v3.1 which ".. supports all the .NET 2.0/3.0 features .. and will also work with .NET Framework 3.0 ".

• ColdFusion 9 uses JNBridgePro v5.1 which "..supports multi-targeting toward .NET 2.0, 3.0, 3.5 and 4.0".
