Run the application

Using the dashboard

The application will issue a certificate. Before you run the application, add support to trust the HTTPS development certificate by running:

    

        
        
            dotnet dev-certs https --trust
        
    

Now run the project:

    

        
        
            cd .\NetAspire.Arm\
dotnet run --project NetAspire.Arm.AppHost 
        
    

The output should look like the text below:

Click on the link generated for the dashboard.

In this case, it is: https://localhost:17222/login?t=81f99566c9ec462e66f5eab5aa9307b0 .

This directs you to the application dashboard, as Figure 1 shows:

On the dashboard, locate and click the endpoint link for NetAspire.Arm.Web.

This takes you to the Blazor-based web application. In the Blazor app, navigate to the Weather section to access and display data retrieved from the WeatherForecast API:

Now return to the dashboard, and select the Traces option. This section provides detailed telemetry tracing, allowing you to view the flow of requests, track service dependencies, and analyze performance metrics for your application:
