In this session we will cover advanced techniques, tips and tricks for creating SharePoint Online apps with Azure and Office 365. Migrating a Sharepoint application from 2010-on-premise to 2013-online is not a straightforward task. Technology changes. No more C# Web Parts on the SharePoint server. How to take the best part of SharePoint servers, Azure servers and PCs? That to do in C#, JQuery? Is there a way to develop one single solution running on-premise and online? Which data access technology to use (SSOM, CSOM, Webservices, REST...)? There is no simple and single answer, but we will give some that we imagined with Redmond's guys, tested and implemented.
