Add a New Content Type Feature
- Right-click the project node in Solution Explorer and select Add|New Item or press CTRL+SHIFT+A to open the Add New Item dialog.
- Select Content Type, enter StoreData as the Name, and click Add.
- The SharePoint Customization Wizard opens. Select Item as the base content type and click Finish.
In actuality, it doesn't matter which base content type selection is made in the wizard because this feature will contain a variety of elements that will replace what Visual Studio generates. At this point you should see some new items in Solution Explorer: a feature named Feature1 and an item named Store Data.
Select Feature1 and press F2 to rename it. Enter StoreData as the new name.
Finally, double-click StoreData to open the feature's designer. Change the Title to Store Data and enter a meaningful description like Fields, Content Types, and Lists for the store.
