Summary

SSRS supplies an infrastructure (interfaces, classes, value types, and customizable configurations) to allow developers to extend SSRS' capabilities. Developers can write extensions to extend security, delivery, data processing, and rendering functionality of SSRS.

Although extensions require more in-depth understanding of SSRS' inner workings and supporting infrastructure, the need to provide custom functionality sometimes takes a developer to the realm of extensions. The experience to see an extension coming to "life" is certainly very rewarding .
