TypeScript output missing from MSBuild published packages

Very quick note on something our lead front-end developer discovered today.
By default, MSBuild will not package up the output generated by the TypeScript compiler.

To correct this, you must update your .csproj

  <Target Name="TypeScriptJsCollectFiles">

    <ItemGroup>

      <_CustomFiles Include=".\**\*.js" />

      <FilesForPackagingFromProject Include="%(_CustomFiles.Identity)">

        <DestinationRelativePath>%(RecursiveDir)%(Filename)%(Extension)</DestinationRelativePath>

      </FilesForPackagingFromProject>

    </ItemGroup>

  </Target>

  <PropertyGroup>

    <CopyAllFilesToSingleFolderForPackageDependsOn>

      TypeScriptJsCollectFiles;

      $(CopyAllFilesToSingleFolderForPackageDependsOn);

    </CopyAllFilesToSingleFolderForPackageDependsOn>

    <CopyAllFilesToSingleFolderForMsdeployDependsOn>

      TypeScriptJsCollectFiles;

      $(CopyAllFilesToSingleFolderForPackageDependsOn);

    </CopyAllFilesToSingleFolderForMsdeployDependsOn>

  </PropertyGroup>
