         https://github.com/3F/DllExport/issues/90#issuecomment-546637702

* NOTE: You need an updated/modern manager to avoid problem
        when "Possible incorrect Sdk-based project types": PR #123
        https://github.com/3F/MvsSln/issues/23

        Use it from official 1.7 release:
        https://github.com/3F/DllExport/releases/tag/v1.7
        https://www.nuget.org/packages/DllExport/1.7.0

        Otherwise you need provide manually msbuild instance
        that can process modern Sdk-types due to modern VS/dotnet sdk
        dependencies for netcore-based projects.

        For example, through hMSBuild https://github.com/3F/hMSBuild
        ```
        DllExport ... -msb hMSBuild
        ```

* NOTE: For command-line mode, To upgrade configured version to 1.7:
        ```
            DllExport -action Upgrade -dxp-version 1.7.0
        ```
