TaskExtension base class
Many tasks inherit from the TaskExtension class, which itself inherits from the Task class. This inheritance chain adds several parameters to the tasks that derive from them. These parameters are listed in this document.
Parameters
The following table describes the parameters of the base classes.
| Parameter | Description |
|---|---|
| BuildEngine | Optional IBuildEngine parameter. Specifies the build engine interface available to tasks. The build engine automatically sets this parameter to allow tasks to call back into it. |
| BuildEngine2 | Optional IBuildEngine2 parameter. Specifies the build engine interface available to tasks. The build engine automatically sets this parameter to allow tasks to call back into it. This is a convenience property so that task authors inheriting from this class do not have to cast the value from IBuildEngine to IBuildEngine2. |
| BuildEngine3 | Optional IBuildEngine3 parameter. Specifies the build engine interface provided by the host. |
| HostObject | Optional ITaskHost parameter. Specifies the host object instance (can be null). The build engine sets this property if the host IDE has associated a host object with this particular task. |
| Log | Optional TaskLoggingHelper read-only parameter. Gets a TaskLoggingHelperExtension object that contains task logging methods. |
