Conclusion

Take Home Points:

1. COM is Microsoft's basic component technology

2. COM+ is a framework providing runtime services to COM class instances

3. COM+ helps developers with Attribute-based programming making it simple

4. COM+ does object housekeeping thus reducing 30% of effort in writing component based software

5. COM+ is flexible security wise and scalable as well

Current State of the art:

• Microsoft is working on a replacement for COM called Common Language Runtime (CLR)
• CLR components will still use COM+ runtime services the same way as COM componets
• In future, COM+ is to be renamed .NET Component Services
