With the webMethods for Microsoft Plug-in installed, you can use Designer to generate services from an existing .NET assembly. This process is referred to as introspection. Designer provides the ability to locate assemblies by browsing the Integration Server directory accessible from the Integration Server and Windows services. When you select an assembly, all public constructors, methods, properties and fields of public classes in that assembly are presented. You can select which services provided by the assembly are exposed as integration services, and subsequently as Web services if required.

After the services of assemblies are exposed as integration services, you can invoke them as you would any other integration service.
