DataSource for Entity Framework includes a C1DataSource which facilitates Rapid Application Development by allowing developers to specify data sources on a rich designer surface that requires little or no additional coding. In addition, the C1DataSource includes classes that provide support for the same features that can be controlled through the designer surface, plus many extra features that provide greater control over it through code.

 We’ll begin our exploration of the C1DataSource component by looking at how we can control it via the designer surface. From there, we’ll explore how it can be controlled dynamically at run time. Not all features available at run time will be represented here. You can consult the "Programming Guide" of this documentation and the Reference for more runtime features, including client-side transaction support and more.
