.NET: IHostedService – hosting services inside any .NET process
Posted by jpluimers on 2019/10/31
Have any service related stuff implement IHostedService, so it is easy to deploy it in all kinds of processes:
- console to test
- windows service
- ASP.NET Core service
- Linux host application

As ASP.NET developers we’re fairly used to hosting our code inside Internet Information Services (IIS). However, since ASP.NET Core is cross-platform, hosting inside IIS isn’t always an option. For that reason, the hosting model for ASP.NET Core applications looks quite a bit different. Of course, we can still host our code in IIS, but we also have the option to use Kestrel and run as a standalone application.This new hosting model is visible in code through the WebHostBuilder API from Microsoft.

Learn about Kestrel, the cross-platform web server for ASP.NET Core.
Kestrel is a cross-platform web server for ASP.NET Core. Kestrel is the web server that’s included by default in ASP.NET Core project templates.
Kestrel supports the following features:
- HTTPS
- Opaque upgrade used to enable WebSockets
- Unix sockets for high performance behind Nginx
Kestrel is supported on all platforms and versions that .NET Core supports.
