Avoid duplicate entries for the same serviced component
|
| Total Hit (2611) |
A common mistake when creating a .NET component that runs under Component Services - that is, a class that inherits from ServicedComponents - is that you forget to assign a fixed version and/or GUID to the component being built.

Take advantage of COM+ object pooling
|
| Total Hit (2660) |
VB6 objects can't be pooled under COM+, because they are apartment threaded. This restriction is void with VB.NET objects (and all .NET objects in general), because they are free-threaded. To make an object poolable you just need to decorate the class with the ObjectPooling attribute:
