Call Azure Service Fabric from outside

I'm playing with Azure Service Fabric and a console app. I simply want my console app to connect to the cluster and do some stuff.

The console app try to resolve the service address with the following:

    static void Main(string[] args)
    {
        ServicePartitionResolver resolver = null;

        try
        {
            resolver = new ServicePartitionResolver(
                new string[] {
                    "localhost:19000",
                    "localhost:19001"
                });

            Uri serviceUri = new Uri("fabric:/StatefullServiceTEST/MyStatefulService");
            ResolvedServicePartition partition = resolver.ResolveAsync(serviceUri, new ServicePartitionKey(), CancellationToken.None).GetAwaiter().GetResult();
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Exception: {ex.Message}");
        }
        Console.WriteLine();
        Console.Write("Press any key to exit...");
        Console.ReadKey();
    }

My problem is that resolver.ResolveAsync throws an exception that doesn't seem to have any connection with Service Fabric:

Unable to cast COM object of type 'System.__ComObject' to interface type 'IFabricApplicationManagementClient10'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{67001225-D106-41AE-8BD4-5A0A119C5C01}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Any ideas on this?

UPDATE

I was not so clear explaining my problem and what I want to achive.

I'm playing with Azure Service Fabric (both stateless and stateful services): my question is: what's the best way to call a micro service hosted in Azure Service Fabric?

You can't use ServicePartitionResolver, it is a reliable service feature and must be called from within a service running in your cluster.

I couldn't understand clearly what you want.

If you want to manage the service and get details about it, like query running instances or replicas, add or remove instances, and so on, Use the Fabric Client, below is a quick snippet, check details here and here:

`

using System.Fabric;
using System.Security.Cryptography.X509Certificates;

string clientCertThumb = "71DE04467C9ED0544D021098BCD44C71E183414E";
string serverCertThumb = "A8136758F4AB8962AF2BF3F27921BE1DF67F4326";
string CommonName = "www.clustername.westus.azure.com";
string connection = "clustername.westus.cloudapp.azure.com:19000";

var xc = GetCredentials(clientCertThumb, serverCertThumb, CommonName);
var fc = new FabricClient(xc, connection);`

or,

If you want to communicate to a running service, like an API, you should use a Reverse Proxy to resolve your services via URL, like the below snippet, more details here:
