Use HAT automation activities in Unified Service Desk
The Hosted Application Toolkit (HAT) provides you with a bunch of automation activities that you can use to automate your hosted applications. To view the HAT automation activities in Visual Studio:
Start Visual Studio, and create a Workflow Activity Library or open a Workflow Activity Library project. More information: How to: Create an Activity Library
If Toolbox is not visible in the workspace area, from the View menu, choose Toolbox to display it.
In Toolbox, right-click and select Choose Items.
In the Choose Toolbox Items dialog box, on the System.Activities Components tab, click Browse to locate and select the Microsoft.UII.HostedApplicationToolkit.Activity.dll file.

After you select the Microsoft.UII.HostedApplicationToolkit.Activity.dll file, the HAT automation activities appear selected in the Choose Toolbox Items dialog box. Choose OK to display them in Toolbox.
