Service Fabric specify fabric url - azure-service-fabric

Question

Is it possible to define which url a service uses instead of the standard fabric:/AppName/ServiceName?
I can't find if this is configurable or not on an application level.

Yes, you can change the name of the service in the ApplicationManifest.xml to something other than the name taken from the service's class name.
Short: just change the name attribute in ApplicationManifest.xml for that service to something else.
In code: If I have this service:
public interface IJustAnotherStatelessService : IService
{
Task<string> SayHelloAsync(string someValue);
}
internal sealed class JustAnotherStatelessService : StatelessService, IJustAnotherStatelessService
{
// Service implementation
}
Registered in Program.cs like this:
ServiceRuntime.RegisterServiceAsync("JustAnotherStatelessServiceType",
context => new JustAnotherStatelessService(context)).GetAwaiter().GetResult();
And in the ServiceManifest.xml for that service
<?xml version="1.0" encoding="utf-8"?>
<ServiceManifest ...>
<ServiceTypes>
<!-- This is the name of your ServiceType.
This name must match the string used in RegisterServiceType call in Program.cs. -->
<StatelessServiceType ServiceTypeName="JustAnotherStatelessServiceType" />
</ServiceTypes>
...
In the ApplicationManifest.xml you will get the suggested name:
<ApplicationManifest ...>
<DefaultServices>
<Service Name="JustAnotherStatelessService">
<StatelessService ServiceTypeName="JustAnotherStatelessServiceType" InstanceCount="[JustAnotherStatelessService_InstanceCount]">
<SingletonPartition />
</StatelessService>
</Service>
</DefaultServices>
</ApplicationManifest>
This will give you an Uri to you service like
fabric:/app_name/JustAnotherStatelessService
Now, go ahead and change the name in the application manifest:
<ApplicationManifest ...>
<DefaultServices>
<Service Name="AwesomeService">
<StatelessService ServiceTypeName="JustAnotherStatelessServiceType" InstanceCount="[JustAnotherStatelessService_InstanceCount]">
<SingletonPartition />
</StatelessService>
</Service>
</DefaultServices>
</ApplicationManifest>
And your service now answers to
fabric:/app_name/AwesomeService

You can use this uri builder (ServiceUriBuilder.cs) class from here: https://github.com/Azure-Samples/service-fabric-dotnet-web-reference-app/blob/master/ReferenceApp/Common/ServiceUriBuilder.cs
For stateless service you can easily get the proxy:
var serviceUri = new ServiceUriBuilder(ServiceName);
var proxyFactory = new ServiceProxyFactory();
var svc = proxyFactory.CreateServiceProxy<IServiceName>(serviceUri.ToUri());
For stateful service you have to specify the partition.
var serviceUri = new ServiceUriBuilder(StatefulServiceName);
var proxyFactory = new ServiceProxyFactory();
//this is just a sample of partition 1 if you are using number partitioning.
var partition = new ServicePartitionKey(1);
var svc = proxyFactory.CreateServiceProxy<IStatefulServiceName>(serviceUri.ToUri(), partition);
