What is web listener web server in asp.net core?


Asked by Charlee Walls on Nov 29, 2021 ASP.NET



Web Listener is one of the servers of .Net core. ASP.NET Core is completely decoupled from the web server environment that hosts the application. ASP.NET Core supports hosting in IIS and IIS Express, and self-hosting scenarios using the Kestrel and WebListener HTTP servers.
Besides,
WebListener is a web server for ASP.NET Core based on the Windows Http Server API. WebListener is a Windows-only HTTP server for ASP.NET Core. It runs directly on the Http.Sys kernel driver, and has very little overhead. WebListener cannot be used with the ASP.NET Core Module for IIS. It can only be used independently.
Keeping this in consideration, ASP.NET Core supports hosting in IIS and IIS Express, and self-hosting scenarios using the Kestrel and WebListener HTTP servers. WebListener is a Windows HTTP server built on the Http.Sys kernel mode driver. It exposes a number of Http.Sys features previously only availabe in IIS.
Just so,
WebListener is a Windows HTTP server built on the Http.Sys kernel mode driver. It exposes a number of Http.Sys features previously only availabe in IIS. Fine, but when should we use Web Listener? If you are on Windows and if you want to expose your server directly to the internet.
In fact,
What is a Kestrel Web Server? As we already discussed the ASP.NET Core is a cross-platform framework. It means it supports developed and run applications on different types of operating systems such as Windows, Linux, or Mac. The Kestrel is the cross-platform web server for the ASP.NET Core application.
