I am trying to implement a discovery feature in Mono.
The goal is a service running a .NET application with Mono on a Raspberry Pi 3 with Raspbian. This application should support a discovery feature.
First I tried it with the WCF Discovery Approach:
host.Description.Behaviors.Add(new ServiceDiscoveryBehavior());
host.AddServiceEndpoint(new UdpDiscoveryEndpoint());
This works perfectly in .NET but does always throws an InvalidOperationException:
Contract 'TargetService' is not implemented in this Service '....'
After some investigation, I figured that this is a Mono problem.
In this post:
Is there any way to use WCF Discovery in mono? They implemented a discovery with Mono.Zeroconf.
So I tried the Mono.Zeroconf approach:
To get it work I compiled the Mono.Zeroconf sources by my self, from here: https://github.com/mono/Mono.Zeroconf.
This worked perfectly in a Windows environment with Bonjour installed.
But the provider for Avahi (which is the Linux equivalent for Bonjour) is outdated.
I managed to compile it anyway, but it does throw some strange exceptions when running under Raspbian / Mono.
So I can not find a solution to discover my Mono project running on a Linux machine from any other (Windows or Linux) environment.
Does anyone have a solution for one of the problems above or a completely new approach?
As long as I can implement it in .NET and run with Mono I am happy to use every solution out there.
