Hi all,

I've just recently started playing with Serviced Components in C#.

I've defined a type like:

[Guid(...)]
public interface IFoo
{
void Method();
}

[Guid(...)]
public class Foo : ServicedComponent, IFoo
{
public void Method()
{
// ...
}
}

When I run regsvcs.exe on the resulting assembly, the type is registered in
COM+ as expected, but so are a number of FCL interfaces and classes;

- _Object
- IDisposable
- IManagedObject
- IRemoteDispatch
- System_EnterpriseServices_IServicedComponentInfo

Also, regsvcs seems to synthesize an interface called _Foo from the class
definition, rather than emitting just IFoo.
None of the FCL types end up in the generated typelib, they are only shown
in the COM+ MMC snap-in.

Is there any way I can suppress the creation of these types, or am I missing
something fundamental?

Hi Kim!

That one is easy. Add another attribute to Foo:
[ ClassInterface(ClassInterfaceType.None) ]
which tells regsvcs to use the interface, and not sintetize a dual interface
instead (and the name suggest it tries to be VB6-like in doing so ;)).

As for the rest of the interfaces, they are needed for a few internal
framwork things, I believe... spelunking with anakrino inside
System.EnterpriseServices.Dll is quite interesting ;)

Cool - thanks! Yeah, that underscore nightmare seems to have no end ;)

I don't mind much, it's just disturbing to the eye. It reminds me of
including shared interfaces in a typelib of the component implementing them,
which can break typelib marshalling. But I assume there's no problem with
running multiple applications with these classes in parallel?

Thanks!

Hi Kim,

There shouldn't, but, overall, remember that this is still COM+ at the
bottom of the stack, meaning the restriction of having one ServicedComponent
in registerd in only one COM+ application at a time (barring the use of COM+
partitions).

Tomas,

I know, that's why I was a bit disturbed by the fact that regsvcs forced the
managed classes into the app... I thought maybe I was doing something wrong,
but I guess it's the way it should be.

Thanks!
