Can Structuremap DefaultConventionScanner find non-public classes

Question

I have just started using StructureMap, having previously worked with Spring.Net. I love the DefaultConventionScanner and the ability to scan assemblies and use convention over configuration to find classes. But there seems to be a limitation that the classes that implement the interfaces must be public, whereas we like to keep out interfaces public and our implementations internal to an assembly.

Is there a way to ask the DefaultConventionScanner to find internal classes as well?

Answer 1

No, and in fact the limitation that classes should be public applies to all of StructureMap - not just the convention scanners. You can register internal types manually with StructureMap if you make use of the InternalsVisibleTo attribute, but it is not well-supported or documented. You will not be able to make an ITypeScanner (like DefaultConventionScanner) that registers internal types because the AssemblyScanner only exposes exported types.
