Got it. Seems to work now, but I am not sure, if I really got it right.  The following code snippet seems to work (cts.signalRId is an SignalR resource ID).

            `ctx.eventSourceSubscription = new EventSubscription("sigrev", new EventSubscriptionArgs()`
            `{`
                `Scope = ctx.signalRId,`
                `IncludedEventTypes = new InputList&lt;string&gt;()`
                `{`
                    `"Microsoft.SignalRService.ClientConnectionConnected",`
                    `"Microsoft.SignalRService.ClientConnectionDisconnected",`
                `},`
                `AzureFunctionEndpoint = new EventSubscriptionAzureFunctionEndpointArgs()`
                `{`
                    `FunctionId = ctx.App.FunctionApp.Id.Apply(x =&gt; string.Format($"{x}/functions/HandleOnConnectionChanged"))`
                `},`
            `})`;
