i imagine this should be a single. https://github.com/Particular/ServiceInsight/blob/master/src/ServiceInsight/Explorer/EndpointExplorer/EndpointExplorerViewModel.cs#L47

since it is assumed to not be null

It could be SingleOrDefault as it stands today (you initially might be disconnected). However the stack trace doesn't tell me how we got there.

A quick 'fix' would be:

if (ServiceControlRoot?.EndpointExists(message.Endpoint) == true) in here.
