アセンブリリファレンスはWPFメトロチャート

Question

で問題がありますので、Torsten Mandelkow ModernUICharts nugetパッケージを使用しようとしています。 私は彼のcodeplexのドキュメントを新しい解決策で追跡することができ、チャートは問題なく現れました。問題は私のプロジェクトの中でそれをやろうとしたときにエラーメッセージが出ます。

The type reference cannot find a public type named 'ChartBase'. Line 18 Position 75.

私は正確にmultible回二つのプロジェクト間でコードをコピーしたことを確実にしましたが、私は同じ結果を得続けます。私はスタックオーバーフローでそれを探してみました1234 成功なし。ここで

が私のコードである
