# Developing a Custom Task

[!INCLUDE[ssis-appliesto](../../../includes/ssis-appliesto-ssvrpluslinux-asdb-asdw-xxx.md)]


  [!INCLUDE[ssISnoversion](../../../includes/ssisnoversion-md.md)] uses tasks to perform units of work in support of the extraction, transformation, and loading of data. [!INCLUDE[ssISnoversion](../../../includes/ssisnoversion-md.md)] includes a variety of tasks that perform the most frequently used actions, from executing an SQL statement to downloading a file from an FTP site. If the included tasks and supported actions do not completely meet your requirements, you can create a custom task.  
  
 To create a custom task, you have to create a class that inherits from the <xref:Microsoft.SqlServer.Dts.Runtime.Task> base class, apply the <xref:Microsoft.SqlServer.Dts.Runtime.DtsTaskAttribute> attribute to your new class, and override the important methods and properties of the base class, including the <xref:Microsoft.SqlServer.Dts.Runtime.Task.Execute%2A> method.  
  
## In This Section  
 This section describes how to create, configure, and code a custom task and its optional custom user interface.  
  
 [Creating a Custom Task](../../../integration-services/extending-packages-custom-objects/task/creating-a-custom-task.md)  
 Describes the first step, which is creating the custom task.  
  
 [Coding a Custom Task](../../../integration-services/extending-packages-custom-objects/task/coding-a-custom-task.md)

 [Connecting to Data Sources in a Custom Task](../../../integration-services/extending-packages-custom-objects/task/connecting-to-data-sources-in-a-custom-task.md)  
 Describes how to connect a custom task to a data source.  
  
 [Raising and Defining Events in a Custom Task](../../../integration-services/extending-packages-custom-objects/task/raising-and-defining-events-in-a-custom-task.md)  
 Describes how to raise events and define custom events from the custom task.  
  
 [Adding Support for Debugging in a Custom Task](../../../integration-services/extending-packages-custom-objects/task/adding-support-for-debugging-in-a-custom-task.md)  
 Describes how to create breakpoint targets in the custom task.  
  
 [Developing a User Interface for a Custom Task](../../../integration-services/extending-packages-custom-objects/task/developing-a-user-interface-for-a-custom-task.md)  
 Describes how to create a user interface that shows in [!INCLUDE[ssIS](../../../includes/ssis-md.md)] Designer to configure properties on the custom task.
