Dataverse Functions are changing how business logic is implemented in the Power Platform — but how do they really work under the hood? In this 300-level session, we’ll go beyond the basics and explore how Functions are stored in Dataverse, how they’re executed internally, and how they compare to Custom APIs and plugins. We’ll also examine how Function security is handled at the table level and what that means for performance and data access. You’ll learn where Functions outperform traditional code-based approaches — and where you’ll still need to reach for C#. Expect live demos, deep metadata analysis, and practical guidance for when to use Functions versus Custom APIs. If you’ve worked with Custom Actions and Custom APIs before, this session will help you understand how Functions fit into the modern Power Platform architecture.
