  <!-- Targets that support static content scenarios in ASP.NET Core.
       The main targets are:
       * GenerateStaticWebAssetsManifest: Creates a manifest file to use in development with
         the paths to all the references packages and projects content roots.
       * ResolveStaticWebAssetsInputs: Collects all the static assets from different sources
         * Current project.
         * Referenced project.
         * Referenced packages.
       * GenerateStaticWebAssetsPackTargets: Includes the static web assets in the current project
         under the 'staticwebassets' folder in the nuget package and generates and includes in the
         package the appropriate .props files to support discovering the packaged static web assets.
       * GetCurrentProjectStaticWebAssets: Called on each referenced project to retrieve the list of
         static web assets in the project.

       This target generates and includes a Microsoft.AspNetCore.StaticWebAssets.props file that
       goes inside the build directory and describes the static web assets in the package as an
       item group.
       This target also generates and includes a $(PackageId).props file under the build, buildMultiTargeting
       and buildTransitive folders that are setup so that:
       * buildTransitive\$(PackageId).props simply imports buildMultitargeting\$(PackageId).props

       * build\$(PackageId).props simply imports Microsoft.AspNetCore.StaticWebAssets.props

       they see fit and to make sure the package works in all scenarios. Authors including custom MSBuild
       targets into their packages are expected to disable the generation of $(PackageId).props files and
       to manually import build\Microsoft.AspNetCore.StaticWebAssets.props in their custom props files.
