Requirements to expose a Clarion .NET component to COM:
·Classes should implement interfaces explicitly.
·Managed types must be marked as public.
·Methods, properties, fields, and events must be marked as public.
·Types must have a public default constructor to be activated from COM.
Also, the Microsoft .NET Framework SDK contains special tools to support exposing any .NET components to COM:
·Type Library Exporter (Tlbexp.exe) - generates a type library that describes the types defined in a common language runtime assembly.
·Assembly Registration Tool (Regasm.exe) - reads the metadata within an assembly and adds the necessary entries to the registry, which allows COM clients to create .NET Framework classes transparently. Once a class is registered, any COM client can use it as though the class were a COM class.
