LoadBalance And Forward

[PaperHammer]

About LoadBalance

builder.AddProject<Projects.ELMS_Micro_UserService>("micro-userservice").WithReplicas(3);

As in the above code, 3 instances of the same webapi service are started. Before . The package for NET 9 P3, Microsoft.Extensions.ServiceDiscovery, can be used like this:

 builder.Services.ConfigureHttpClientDefaults(static http =>
 {
     // Turn on service discovery by default
     http.UseServiceDiscovery(RandomServiceEndPointSelectorProvider.Instance);
 });

I wonder if there is a similar way to implement load balancing in Aspire

About Forward

In one project, there is a gateway and some microservices. In general, the gateway accesses the API of the access registry, and the service registry automatically creates the corresponding HttpClient instance through load balancing and other methods to forward the request to the corresponding microservice.
Such as:

app.MapGet("/CallGetApi",
    async (IHttpClientFactory factory, ILogger<Program> logger) =>
{
    var client = factory.CreateClient("shipping");

    HealthCheckResult healthCheckResult;
    do
    {

        var healthCheckService = new ShippingHealthCheck(factory);
        healthCheckResult = await healthCheckService.CheckHealthAsync(new HealthCheckContext { });

        if (healthCheckResult.Status != HealthStatus.Healthy)
        {
            logger.LogError("Shipping service is not healthy.");
            client = factory.CreateClient("shipping");
        }
    }
    while (healthCheckResult.Status != HealthStatus.Healthy);

    var response = await client.GetStringAsync(
        $"http://shippingForProcessString/ProcessString/SendToProcessNumber");

    return $"Shipping ProcessString API returned: {response}";
});

I wonder if there is a similar operation in the AppHost project in Aspire?
