问题
I have an Azure WebRole, which publishes a WCF Service with PerSession setting. This means, session needs to be preserved for a long time... This is because of synch-framework and cannot be changed.
Now I have the problem when I want to use Multi-Instances on that Web Role (Classic Azure Cloud Service)
Can I configure an Application Gateway with endpoints not to the Public WebRole but to each Instances, so that the Gateway handles the Balancing? How?
Thanks

Technically, the Application Gateway support for multi-tenant backends, you could configure an IP address or FQDN of your instances in the backends. Here is a quickstart: Direct web traffic with Azure Application Gateway - Azure portal
However, the Application Gateway is known as application layer (OSI layer 7) load balancing which enables you to manage traffic to your web applications. Perhaps the traditional layer 4 load balancer is better for balancing WCF Service. Moreover, In Cloud Services, you get a load balancer automatically configured when you create the service. You could get more explanation in this question.
