: It ensures that an application only uses APIs available in that specific version, preventing "missing method" errors when the app is deployed to a machine with only that version of the runtime.
To avoid future headaches, adopt these best practices.

But what exactly is it? Put simply, the Multi-Targeting Pack allows developers using a newer version of Visual Studio (such as Visual Studio 2017, 2019, or 2022) to write code that targets the runtime environment. It provides the reference assemblies, the IntelliSense metadata, and the build tooling necessary to simulate an older development environment without actually downgrading your entire IDE.
Visual Studio 2022 is 64-bit and may have compatibility checks.
A multi-targeting pack (or MT pack) is a set of reference assemblies . Unlike a runtime, which contains the actual logic to execute code, reference assemblies contain only the metadata and signatures (no method bodies) required for a compiler to understand the API surface of a specific framework version.

: It enables an IDE like Visual Studio to show older framework versions in the "Target Framework" dropdown of a project's properties.
