### <a id="rids"></a>Creating Per-RuntimeIdentifier packages

You'll need a few things
You'll need to perform a few simple steps:

1. Make sure to use `TargetFrameworks` instead of `TargetFramework`, even if you're only building a single target framework. I am piggy-backing off of its looping capabilities.
2. Set the `RuntimeIdentifiers` property to [valid RID's](https://docs.microsoft.com/en-us/dotnet/core/rid-catalog) ([full list](https://github.com/dotnet/runtime/blob/master/src/libraries/pkg/Microsoft.NETCore.Platforms/runtime.json)), separated by a semi-colon. (`<RuntimeIdentifiers>win;unix</RuntimeIdentifiers>`). These can be set per TFM using a condition on the property. This lets you have multiple TFM's, but only some of which have RID's.
3. For the TFM's that you want want to build separately, set the property `ExtrasBuildEachRuntimeIdentifier` to `true`.
2. Set the `RuntimeIdentifiers` property to [valid RID's](https://docs.microsoft.com/en-us/dotnet/core/rid-catalog) ([full list](https://github.com/dotnet/runtime/blob/master/src/libraries/pkg/Microsoft.NETCore.Platforms/runtime.json)), separated by a semi-colon (`<RuntimeIdentifiers>win;unix</RuntimeIdentifiers>`).
3. For the TFM's that you want want to build separately, set the `ExtrasBuildEachRuntimeIdentifier` property to `true`.

Note: You must use the `Sdk="MSBuild.Sdk.Extras"` method for this. Using `PackageReference` is unsupported for this scenario.
When you're done, you should be able to run build/pack and it'll produce a NuGet package.

While the Visual Studio context won't show each RID, it'll build for each. The Extras defines a symbol for each RID for use (`win-x86` would be `WIN_X86` and `centos.7-x64` would be `CENTOS_7_X64`). Dots and dashes become underbars.
Notes:
* You must use the `Sdk="MSBuild.Sdk.Extras"` method for this. Using `PackageReference` is unsupported for this scenario.
* While the Visual Studio context won't show each RID, it'll build for each.
* The Extras defines a preprocessor symbol for each RID for use (`win-x86` would be `WIN_X86` and `centos.7-x64` would be `CENTOS_7_X64`). Dots and dashes become underbars.
* The default path for per-RID output assemblies and symbols in NuGet package is `runtimes/<RuntimeIdentifier>/lib/<TargetFramework>`.
* `RuntimeIdentifiers` can be set per-`TargetFramework` using a condition on the property. This lets you have multiple TFM's, but only some of which have RID's.

You will also need a Reference Assembly for the `ref` folder. Please see my [two](https://claires.site/2018/07/09/create-and-pack-reference-assemblies-made-easy/) [blogs](https://claires.site/2018/07/03/create-and-pack-reference-assemblies/) articles for details.

When you're done, you should be able to build/pack these and it'll create a NuGet package. Your per-RID targets will be in `runtimes/<rid>/lib/<tfm>` and the Reference Assembly will be in `ref/<tfm>`.
#### Reference Assemblies
You will likely need to create reference assemblies to simplify development and consumption of your libraries with complex flavor (`TargetFramework` × `RuntimeIdentifier`) matrix.
Reference assemblies are packed into `ref/<TargetFramework>` folder. Please see my [two](https://claires.site/2018/07/09/create-and-pack-reference-assemblies-made-easy/) [blogs](https://claires.site/2018/07/03/create-and-pack-reference-assemblies/) articles for details.

#### Packing additional contents
If you need to add native assets into runtimes, the easiest way is to use:
```xml
<None Include="path/to/native.dll" PackagePath="runtimes/<rid>/native" Pack="true" />
```

#### Overriding content paths in output package
Minimal example to pack output assemblies and symbols to `tools` (instead of `runtimes`) subfolders.
```xml
<PropertyGroup>
<ExtrasIncludeDefaultProjectBuildOutputInPackTarget>IncludeDefaultProjectBuildOutputInPack</ExtrasIncludeDefaultProjectBuildOutputInPackTarget>
</PropertyGroup>

<Target Name="IncludeDefaultProjectBuildOutputInPack">
<ItemGroup>
<None Include="@(RidSpecificOutput)" PackagePath="tools/%(TargetFramework)/%(Rid)" Pack="true" />
</ItemGroup>
</Target>
```

`<None Include="path/to/native.dll" PackagePath="runtimes/<rid>/native" Pack="true" />`
For advanced options, see _ClasslibPack*_ SDK tests and _RIDs.targets_ file.
