Lab Management Workflow Activities
When you customize a Lab Management workflow template (LabDefaultTemplate.11.xaml), you can use one or more of the pre-defined Lab Management activities. You can also access objects that are created by the Lab Management wizard. This topic describes the Team Foundation Lab Management activities and objects that are available when you customize a workflow template to build, deploy, and test your application. For information about how to use these activities in a customized workflow, see Customizing Lab Management Workflow.
Requirements
- Visual Studio Ultimate, Visual Studio Premium, Visual Studio Test Professional
This topic contains the following sections:
