Component developers benefit from COM+ queued components on different levels. First, they take away the need to handcraft asynchronous method invocation solutions, allowing developers (as with the other COM+ component services) to focus on the business problem at hand. Second, and perhaps just as important, queued components’ ability to take seamless advantage of other COM+ services, such as transactions and role-based security, is something that would be almost impossible to provide in a custom solution. You can even combine queued components with COM+ loosely coupled events, the subject of the next chapter.
