## Create a host using `nethost.h` and `hostfxr.h`

The following steps detail how to use the `nethost` and `hostfxr` libraries to start the .NET Core runtime in a native application and call into a managed static method. The [sample](https://github.com/dotnet/samples/tree/master/core/hosting/HostWithHostFxr) uses the `nethost` header and library installed with the .NET SDK and copies of the [`coreclr_delegates.h`](https://github.com/dotnet/runtime/blob/master/src/installer/corehost/cli/coreclr_delegates.h) and [`hostfxr.h`](https://github.com/dotnet/runtime/blob/master/src/installer/corehost/cli/hostfxr.h) files from the [dotnet/runtime](https://github.com/dotnet/runtime) repository.

### Step 1 - Load `hostfxr` and get exported hosting functions

The `nethost` library provides the `get_hostfxr_path` function for locating the `hostfxr` library. The `hostfxr` library exposes functions for hosting the .NET Core runtime. The full list of functions can be found in [`hostfxr.h`](https://github.com/dotnet/runtime/blob/master/src/installer/corehost/cli/hostfxr.h) and the [native hosting design document](https://github.com/dotnet/runtime/blob/master/docs/design/features/native-hosting.md). The sample and this tutorial use the following:

The sample and this tutorial use the following:

* `hostfxr_initialize_for_runtime_config`: Initializes a host context and prepares for initialization of the .NET Core runtime using the specified runtime configuration.
* `hostfxr_get_runtime_delegate`: Gets a delegate for runtime functionality.
