Developing Applications for SharePoint 2010 contains guidance documentation, detailed examples, and a reusable class library. These resources are designed to help solution developers and architects make the right decisions and follow proven practices when designing and developing applications for Microsoft SharePoint 2010. The guidance focuses on the building blocks that every developer needs to understand to become an effective SharePoint developer or architect. The guide is provided as a Help (.chm) file and has four core areas: application foundations, execution models, data models, and client models. Eight reference implementations illustrate the core concepts covered in the guide. The reusable class library provides code to help developers build more manageable, flexible, and testable applications. Source code is provided for all reference implementations and for the reusable library. The reference implementations have automated setup scripts to configure the applications.
