.net - アセンブリローダーの紛らわしい動作

Question

カスタムビジュアルデザイナーを実装する VS2012 パッケージ (SDK を使用) を開発しています。ソリューションには、いくつかのプロジェクトが含まれています。VS 実験インスタンスでパッケージを実行し、カスタムビジュアルデザイナーを開こうとすると、次の例外が発生します。

System.IO.FileNotFoundException was unhandled by user code
  HResult=-2147024894

アセンブリバインディングの問題のように見えるので、Fusion Log Viewerを調べて、アセンブリローダーエラーに関する追加情報を取得することにしました。

奇妙なことに、Fusion のログによると、ビジュアルデザイナーを開こうとすると、4 回の読み込み試行VisualDesigner.Configurationがあり、2 回は成功しましたが、2 回失敗しました。

なぜそれが起こるのか分かりません。最初は正常にロードされたのに、その後このアセンブリをロードすると失敗するのはなぜVisualDesigner.Configurationですか?

Calling assembly : (Unknown).また、アセンブリのバインドに失敗した場合にログに記載されているのはなぜですか?
