How to add a custom category to UiPath's Project Settings from your activity package, register fields at design time via IRegisterWorkflowDesignApi, and read those values back at runtime through IExecutorRuntime — with the App Insights instrumentation key as the example.

A modern UiPath custom activity needs more than a CodeActivity: a DesignPropertiesViewModel, an embedded metadata file for the toolbox, private host-supplied references, and the right System.Activities assembly version. Here's the whole recipe.

There's no public hook to run code around every UiPath activity in the Robot. CoreWF's TrackingParticipant gets you the events, and a small reflection bridge into the live executor attaches it from inside a running workflow — so a single Super Initialize activity instruments the whole run.

Ship a Workflow Analyzer rule inside your UiPath activity package: register it with IRegisterAnalyzerConfiguration, scope it to the workflow so the result lands on the right file, detect the project's entry point, and walk the activity tree — with the gotcha that InspectionResult has no File property.
