Task element in an MSBuild project file creates an instance of a task, sets properties on it, and executes it. The
Output element stores output parameters in properties or items to be used elsewhere in the project file.
If there are any OnError elements in the parent
Target element of a task, they will still be evaluated if the task fails and
ContinueOnError has a value of
false. For more information on tasks, see Tasks.
The following code example creates an instance of the Csc task class, sets six of the properties, and executes the task. After execution, the value of the
OutputAssembly property of the object is placed into an item list named
