How to: Use Extensions in a LightSwitch Project
You use different types of extensions in different ways. Custom data type extensions appear in the Type list in the Data designer when you choose a compatible data type. For example, the Image custom data type extension becomes available when you choose the Binary data type.
Custom control extensions appear in Screen Content Tree lists in the Screen designer. For example, a custom Masked Edit control appears wherever a TextBox is available. The following procedures describe how to use theme and shell extensions.
Extensions are available only if they're enabled in the Extensions tab of the Application designer. See How to: Add or Remove Extensions.
