+> The `nethost` and `hostfxr` hosting APIs only support framework-dependent deployments. Self-contained deployments should be treated as stand-alone executables. If you're evaluating deployment models for your application, use a framework-dependent deployment to ensure compatibility with these native hosting APIs.

 ## Create a host using `nethost.h` and `hostfxr.h`
 
 A [sample host](https://github.com/dotnet/samples/tree/main/core/hosting) demonstrating the steps outlined in the tutorial below is available in the dotnet/samples GitHub repository. Comments in the sample clearly associate the numbered steps from this tutorial with where they're performed in the sample.
