.NET 9.0 ASP.NET Core Hosting Bundle9.0.22

It equips a Windows server to run ASP.NET Core web applications built for .NET 9.0, providing the components required to serve them in production. The bundle connects ASP.NET Core with Internet Information Services (IIS) through the ASP.NET Core Module, allowing IIS to manage incoming web requests and hand application processing to the .NET runtime.

Administrators typically use it when publishing an ASP.NET Core site or API to IIS, while developers use it to reproduce a supported hosting environment for deployment testing. Its inclusion of the ASP.NET Core runtime and IIS integration distinguishes it from a development-only .NET installation, because it prepares a Windows machine specifically for web application hosting. It can support common IIS deployment arrangements, including applications hosted inside the IIS worker process or run behind IIS as a separate process.

Published by Microsoft, .NET 9.0 ASP.NET Core Hosting Bundle belongs to the Developer Tools category and is distributed under an open-source license. The current version is 9.0.22, and its target platform is Windows. Users should match the bundle to ASP.NET Core applications targeting the .NET 9.0 generation and place it on the Windows server that will host those applications. It is intended for organizations, teams, and individuals deploying Microsoft-based web services where IIS is the selected web server.
