A front-end computing system initializes an instance of a workflow. The workflow contains a plurality of activities. The plurality of activities includes a shim activity. When the front-end computing system executes the workflow instance, the front-end computing system performs the shim activity. When the front-end computing system performs the shim activity, the front-end computing system sends a custom activity assembly to a sandbox computing system. The custom activity assembly is not fully trusted. The sandbox computing system executes the custom activity assembly. The sandbox computing system is isolated from the front-end computing system such that unexpected behavior of the sandbox computing system does not cause the front-end computing system to perform unexpected behavior. |
