Develop for Changing Requirements With Custom Metadata Types (1)

Business requirements are constantly changing. Make your code more resilient to change by implementing Custom Metadata Types. In this session, we'll show you how to use Custom Metadata Types to easily add configuration to your code. We'll compare them to Custom Settings and illustrate when to use each. We will also cover testing strategies for code that uses Custom Metadata Types. Attendees will leave with an understanding of how to use this excellent feature and a Github library full of samples.
