Create an external list using an OData data source in SharePoint
Learn how to create an external list programmatically and bind it to an OData-based external content type in SharePoint. Although a power user or SharePoint administrator will likely create an external list using SharePoint Designer 2013, a developer will be interested in the ability to create external lists using the tools of their trade, Visual Studio 2012 and the Office Developer Tools for Visual Studio 2012. This gives them more flexibility to add functionality and to package a solution that includes Business Connectivity Services (BCS) features for later deployment into one or many host environments.
Prerequisites for creating an external list
The following components are needed to create an external list from an OData source:
Visual Studio 2012
SharePoint
Office Developer Tools for Visual Studio 2012
A published external content type based on an OData source: For instructions, see How to: Create an external content type from an OData source in SharePoint.
For information about setting up a SharePoint development environment, see Set up a general development environment for SharePoint.

Create a new external list
The following procedures will show you how to create a new external list, bind it to OData-based external content type, and publish to SharePoint using Visual Studio 2012.
Note
The first step assumes that you have successfully created an external content type, as described in How to: Create an external content type from an OData source in SharePoint.
To add an external list automatically
If you just want to add a simple list to your project that reflects what is in your external content type, you can use the Visual Studio 2012 autogeneration tools. The list is created when the external content type is created. When you select the Create list instances for the selected data entities (except Service Operations) check box found in the second step of the autogeneration process (Select the Data Entities step), the wizard creates the XML declarations and add new external content types for each entity you selected.
Press F5 to deploy the project, and the new list is also deployed.
For testing purposes, you may want to modify the AppManifest.xml file so that the starting page of the app is the list you just created.
To modify the AppManifest.xml file
Open the AppManifest.xml file using an XML editor.
Find the <StartPage> tag.
Change the value to
~appWebUrl/Lists/Employees.Save your changes.
To publish the project
Press F5 to deploy your project and external list.
Open a web browser, and navigate to the new list you created.
