You can add new workflow activities to your UBIK® system via plugins loaded by the Injection Management.
Prerequisites
The new activity needs to be placed in an UBIK® plugin which have to implement the interface UBIK.WorkflowBase.IUBIKActivity and inherit from System.Activities.NativeActivity<T>. Although there is no technical need for it we recommand that every activity should at least implement this interface.
The interface is located in the UBIK.WorkflowBase which has to be referenced therefor.

 | The injection of workflow activities is only supported if the plugin is placed within Injection under the UBIK installation directory. Make also sure this folder is configured as probing path in the config file. |
