Unity - map a class to what it handles by interface?

[Merrion]

I was massively overthinking/overengineering this. Instead of all that effort, I simply add the handler class to the container using the name of the cdefinition class it handles...

Public Shared Function GetNameFromCommandDefinition(ByVal handler As Type) As String
 
        'find out what tyoe the handler handles...
        Dim handlerInterface As Type = handler.GetInterface("ICommandHandler`1", False)
        If (handlerInterface IsNot Nothing) Then
            ' Get the name of the first generic class
            If (handlerInterface.GetGenericArguments.Count > 0) Then
                Return handlerInterface.GetGenericArguments(0).Name
            End If
        End If
 
        Return handler.Name()
 
 
    End Function

(This function goes in the initial container registration code e.g. )

Public Shared Sub RegisterTypes(container As IUnityContainer)
 
        Dim interfaceType As Type = Nothing
 
        'Get the interface definition for the generic interface we are looking for
        interfaceType = GetType(ICommandHandler(Of ))
 
        container.RegisterTypes(AllClasses.FromAssembliesInBasePath(includeUnityAssemblies:=False, includeSystemAssemblies:=False).Where(Function(t) t.ImplementsInterface(interfaceType)),
                                getName:=Function(i) GetNameFromCommandDefinition(i),
                                getLifetimeManager:=Function(i) WithLifetime.PerThread(i))
End Sub

Since there is a one-to-one mapping this works fine.
