.NET 8.0 ASP.NET Core Hosting Bundle8.0.33

Host ASP.NET Core web applications on Windows by installing the runtime components and IIS bridge they need to run as managed web services. The .NET 8.0 ASP.NET Core Hosting Bundle combines the ASP.NET Core Runtime, the .NET Runtime, and the ASP.NET Core Module for IIS, connecting IIS request handling with an application’s ASP.NET Core process. This lets an administrator publish an application to a server and place it behind IIS, using site bindings and IIS process controls alongside ASP.NET Core.

For development teams, it addresses the deployment gap between a built application and a server prepared to host it, supplying server-side runtime infrastructure rather than an authoring toolset. System administrators and developers commonly use it for internal portals, APIs, and public-facing ASP.NET Core sites hosted through IIS. Its distinguishing feature is the direct integration of the ASP.NET Core runtime with Microsoft’s IIS hosting model, instead of treating web-server integration as a separate component to configure.

Microsoft publishes this Developer Tools package as open-source software. The current release is version 8.0.33, belonging to the .NET 8.0 ASP.NET Core hosting line. Before installation, the target server should be a supported Windows host, and the application should target the .NET 8.0 runtime family so the deployed workload matches the bundled components. Teams normally build and publish the application through their existing development process before transferring it to the hosting server.
