This was my test: set attribute [ObjectPoolingAttribute(true,100,10000)] create 2,000 instances. Dispose of them create 2,000 more... |

| Can Message sinks work with Serviced components (2 replies) |
| microsoft.public.dotnet.framework.component_services |

Does anyone know why this would be? i.e... |
