Smi.NetCore.Extensions.Hosting 1.0.0

Smi.Microsoft.NetCore.Extensions

A collection of useful extensions for .NET Core applications

1. Smi.NetCore.Extensions.Hosting

Purpose

Whilst working with an ASP.NET Core app, we have the hosting infrastructure to leverage. IWebHostBuidler exposes this and the default project template creates a Program.cs that calls into Startup.cs to bootstrap the application. For non ASP.NET application, we have IHostBuilder and IHost to use.

By default, using the Microsoft.Extensions.Hosting.Abstractions and Microsoft.Extensions.Hosting packages creates a Program.cs that has more than once concern thrown in:

• Create the Host
• Read and Wire up configuration from various sources
• Map custom services into the dependency injection container.

This project aims to provide infrastructure that lets one create a console hosted application similar to an ASP.NET application with cleanly separated Program and Startup such that:

• Program.cs has the sole responsibility of creating the host and specifying the Startup class
• Startup.cs has the responsibility of configuring the application processing pipeline and dependency injection.

How to use

1. Add a reference to Smi.NetCore.Extensions.Hosting in your dotnet core console app
2. Initialize your host like so:

public class Program
    {
        public static async Task Main(string[] args)
        {
            // NOTE: TimedHostedService is an IHostedService implementation
            // Startup is a class that implements the IStartup interface
            await DefaultConsoleHost
                .CreateBuilder<TimedHostedService>(   
                    args, 
                    "MYAPP_",
                    nameof(Sample.ConsoleApp))
                .UseStartup<Startup>(args)
                .RunConsoleAsync();
        }
    }

Your application can now run as a daemon/service/dockerised app.
