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?

I think you just have to install the version you want to use then uninstall and reinstall the .net integration service. – Alegre

So to your knowledge there is no maximum .NET version? – Cuss

IIRC, the max for CF8 is v3.5. – Medallion

@Travis may have missed one step. Somewhere along the line you have to produce something in .net using the higher framework and then try to access it with CF. – Vardar

@Medallion do you know where that's documented? – Cuss

@Cuss - Sorry, I do not remember where I read that offhand. Maybe poke around adobe's site (release notes and such) I just remember that v4.0 support was not added until CF9.0.1. – Medallion

The most definitive reference I could find was the JNBridge docs ie cf_root\jnbridge. (JNBridge is bundled with CF and used for .NET interop). 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 includes JNBridgePro v5.1 which "..supports multi-targeting toward .NET 2.0, 3.0, 3.5 and 4.0". – Medallion

(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".
