.NET 9.0 .NET Runtime9.0.22

It lets Windows run applications built for Microsoft’s .NET platform by supplying the runtime environment those programs expect. Rather than providing an end-user workspace, it works behind the scenes when a compatible .NET application starts and needs its execution components. This addresses the problem of having a .NET application available but lacking the platform runtime required to run it.

Developers can use it as the execution layer for testing .NET 9.0 applications on Windows, while organizations can deploy it on systems whose users need to run such software. Its role centers on executing already-built applications instead of providing a general-purpose development workspace. The runtime is part of Microsoft’s official .NET 9.0 release line and is published by Microsoft.

The package is for Windows and appears in the Developer Tools category. Version 9.0.22 supplies the runtime component associated with .NET 9.0 applications. It is released under an open-source license, making it suitable for teams evaluating developer tooling for development or deployment. Its intended audience therefore includes developers preparing .NET software and people running applications that depend on the .NET 9.0 runtime.
