Enterprise Library and .NET 4.0 Configuration

Question

I have a class library created in .NET 4.0. When I use the corporate library configuration tool to download this assembly, I get:

Assembly load error: Could not load file or assembly. This assembly is built using a runtime that is newer than the currently loaded runtime and cannot be loaded.

I tried the Configuraiton tool in both the Enterprise Application blocks and in beta versions 4.1 and 5.0..NET 4.0 is not supported by the configuration tool.
