Thanks to @Siderite Zackwehdex’s comment, I was able to find the full stack trace of the underlying exception in EventViewer, under:
Windows Logs\Application
In my case, my service is named “HttpDispatcher”, which appears in the “Source” column in the top pane.
I could see immediately it was due to a dependency issue where my .NET 4.7.2 project was not pulling across my .NET Standard references. (That ol’ chestnut).
