| # Host PowerShell Core in .NET Core Applications |
|
|
| ## PowerShell Core v6.0.1 and Later |
|
|
| The runtime assemblies for Windows, Linux and OSX are now published in NuGet package version 6.*. |
| |
| Please see the [.NET Core Sample Application](#net-core-sample-application) section for an example that uses PowerShell Core NuGet packages. |
| |
| ## .NET Core Sample Application |
| |
| Note: The .NET Core `2.1` runtime and .NET Core SDK `2.1` or higher is required for the examples below: |
| |
| - [sample](./sample) |
| |
| You can find the sample application project `MyApp` in each of the above 2 sample folders. You can quickly test-run it using `dotnet run`. |
| To build the sample project properly for distribution, run the following command (make sure the required .NET Core SDK is in use): |
| |
| ```powershell |
| dotnet publish .\MyApp --configuration release |
| ``` |
| |
| This builds it for the runtimes specified by the `RuntimeIdentifiers` property in the `.csproj` file. |
| Then you can run the `MyApp` binary from the publish folder and see the results: |
| |
| ```none |
| PS:> .\MyApp.exe |
| |

| |
| System.Management.Automation.ActionPreference |
| System.Management.Automation.AliasAttribute |
| ``` |
| |
| ## Special Hosting Scenario For Native Host |
| |
| There is a special hosting scenario for native hosts, |
| where Trusted Platform Assemblies (TPA) do not include PowerShell assemblies, |
| such as the in-box `powershell.exe` in Nano Server and the Azure DSC host. |
| |
| For such hosting scenarios, the native host needs to bootstrap by calling [`PowerShellAssemblyLoadContextInitializer.SetPowerShellAssemblyLoadContext`](https://learn.microsoft.com/dotnet/api/system.management.automation.powershellassemblyloadcontextinitializer.setpowershellassemblyloadcontext). |
| When using this API, the native host can pass in the path to the directory that contains PowerShell assemblies. |
| A handler will then be registered to the [`Resolving`](https://github.com/dotnet/corefx/blob/d6678e9653defe3cdfff26b2ff62135b6b22c77f/src/System.Runtime.Loader/ref/System.Runtime.Loader.cs#L38) |
| event of the default load context to deal with the loading of assemblies from that directory. |
