How can I make a feature receiver in sp 2010?
Feature Receiver
Windows SharePoint Services 3.0 added the Feature framework, which provides SharePoint site developers and owners a way to inject functionality into existing sites and deploy custom solutions, such as workflow templates that are developed in Microsoft Visual Studio. Features can also be used for timer job deployment. Although the Feature schema does not provide a way to do this, the Feature Activated and Deactivating events can be caught with custom code to handle the installation and uninstallation of a timer job.
