Adding the Activity to the Toolbox Across Projects

By default, the activity is available on the toolbox to projects in the current solution. In this section, you learn to make the activity accessible from the toolbox across workflow projects outside of the current solution as well. Installing an item on the Visual Studio toolbox that can be seen across workflow projects is not specific to WF. It requires creating a .vscontent file and a .vsi file.

Creating the VSContent File

The .vscontent file contains the name of the category the toolbox menu item is added to and the name of the DLL in the FileName element. The DisplayName and Description elements are set to Custom Activities. The rest of the information is boilerplate.
