Simplified targeting, packaging and deployment of an application and it's supporting libraries.

Note The MultiTarget system is not designed to be used outside the Windows Community Toolkit or Toolkit Labs.

<MultiTarget> is a custom property that indicates which target a component is designed to be built for / run on.

The supplied targets are used to create project references, generate solution files, enable/disable TargetFrameworks, build nuget packages, and more.

Create a MultiTarget.props file in the root of your source project to change the platform targets for your component. This will be picked up automatically by your sample project, unless it has a MultiTarget.props of its own defined.

By default, all available targets are enabled:

<Project>
    <PropertyGroup>
        <MultiTarget>uwp;wasdk;wpf;wasm;linuxgtk;macos;ios;android;</MultiTarget>
    </PropertyGroup>
</Project>

For example, to only target UWP, WASM and Android:

<Project>
    <PropertyGroup>
        <MultiTarget>uwp;wasm;android</MultiTarget>
    </PropertyGroup>
</Project>

The script GenerateAllProjectReferences.ps1 will scan for toolkit components and generate .props files for each.

The <MultiTarget> property is used to define the TargetFrameworks supported by that project. Projects packed into a NuGet packages will reflect this.
