It was once the case (in the previous in-process model of Azure Functions), that one could decorate a function that had no input bindings with a [NoAutomaticTrigger] attribute, and then invoke the function either via through Azure Portal or the Function App’s HTTP management interface (not to be confused with a HTTP input binding).

I’m moving some code over to .NET 8 using the isolated worker model functions and can’t seem to find the equivalent of the [NoAutomaticTrigger] – does anybody know if this functionality is still available, and if so how it can be achieved?
