Summary

The WebApplication derives from DefaultApplication.
As the names states, the implementation is for web based applications.

Sample implementation

public class Program
{
    public static void Main()
    {
        WebApplication
            .ConfigureApp()
            .ConfigureServices(x =>
            {
                // Additional dependencies...
            })
            .Build()
            .Run();
    }
}

Configuration

The Web section of the configuration defines behavior related to the application. The section is deserialized into an instance of WebOptions, and injected as dependency during startup, thus available for injection throughout the application.

See Appendix - App Settings for details about the web section and the meaning of the variables.

Injected Services

When building the WebHost, dependencies related to hosting is configured and initialized. This evolves around defining the process and environment in which the application is executing in.

Dependencies:

• Nano.Web.WebOptions
• Nano.Web.WebApplication
• Nano.Web.Middleware.Hosting.ExceptionHandlingMiddleware
• Nano.Web.Middleware.Hosting.HttpRequestIdentifierMiddleware
• Nano.Web.Middleware.Hosting.HttpRequestUserMiddleware

For a full list of services and dependencies, see Injected Dependencies
