Sandboxed Solutions are the development paradigm for SharePoint Online. In this session, you’ll learn about sandboxed solutions including how to develop, debug and deploy solutions. You’ll also learn the breadth of solutions that can be developed in the sandbox and strategies for developing common scenarios that are not enabled in the sandbox. We are going to discuss tools that can help us develop solutions in a sandbox and tricks that can assist us to streamline code development and application life cycle. The session will be accompanied with series of demoes that are going to show some of best and worst practices with SharePoint solutions.
