Create an second service to your application

Goal

The goal of this section is to add a second service to your .net core application and run it in Mesh.

Process

Step	Procedure
Create a second service for our Service Fabric Mesh Application using Visual Studio	We will use Visual Studio to create a Service Fabric application hosting the container
Setup communication between the services	Using HTTPClient to communicate
Debug and deploy the services	We will see it running in Mesh

Add a second to the Service Fabric Application

1. In Visual Studio right-click the Service Fabric Mesh Application project and choose Add --> New Service Fabric Service

2. Choose ASP.NET Core and click Next

3. Choose the API template

4. Open the ValuesController.cs file in the Controllers folder

5. Substitute the Get() method with this method:

    public String Get()
    {
        return "Hello from the other side";
    }

1. Save the file

Setup communication between the services

1. Open the About.cshtml.cs file in the first project you created

2. Add the following code snippet to replace the OnGet method

    public async Task OnGet()
    {
        HttpClient client = new HttpClient();
        string response = await client.GetStringAsync("http://web1:2008/api/values);

        Message = response;
    }

Note Make sure to make the URL match the name of the new WebAPI service you created, as well as the port it's listening on. The port, can be found in the service.yaml file in the WebAPI project.

Deploy the new version to Azure Service Fabric Mesh

1. To publish the updated application to Service Fabric Mesh in Azure, Right-click the Service Fabric Mesh application project and choose Publish

2. The publish dialog should have stored the information and you can click Publish

This will kick-off a rebuild and deployment of the containers. Once finished go to the web site. You can also browse the Azure portal to see the environment variable that the container is running with.
