The runtime includes the CoreCLR (the .NET Core Common Language Runtime), the base class libraries, and the hosting components. It ensures that your applications run consistently across platforms.
Key Features+
- Cross‑platform support (Windows, Linux, macOS)
- High performance and low memory footprint
- Side‑by‑side versioning
- Self‑contained deployments
- Native interoperability and JIT/AOT compilation
