Creating an IDO extension class project
Substitute a meaningful name for the assembly-name parameter. You can specify any name, but typically, the name of the IDO project associated with the classes in this assembly is used. When this class library is imported to the IDO Extension Class Assemblies form, the name you specify here becomes the name of the assembly.
Caution:
If you add a reference to another assembly from your IDO extension class assembly, the referenced assembly must also be imported as another custom assembly. When .NET tries to locate the referenced assembly, the IDO runtime service searches the database for a matching assembly and loads it on demand.
