# Host in ASP.NET Core
|
||
|
|
|
||
|
|
.NET apps configure and launch a *host*. The host is responsible for app startup and lifetime management. Two host APIs are available for use:
|
||
|
|
|
||
|
|
* [Web Host](xref:fundamentals/host/web-host) – Suitable for hosting web apps.
|
||
|
|
* [Generic Host](xref:fundamentals/host/generic-host) (ASP.NET Core 2.1 or later) – Suitable for hosting non-web apps (for example, apps that run background tasks). In a future release, the Generic Host will be suitable for hosting any kind of app, including web apps. The Generic Host will eventually replace the Web Host.
|
||
|
|
|
||
|
|
At this time, developers should use the [Web Host](xref:fundamentals/host/web-host) based on [WebHostBuilder](/dotnet/api/microsoft.aspnetcore.hosting.webhostbuilder) for hosting ASP.NET Core apps.
