Expression Blend 4 ベータ版と共に VS 2010 を実行しています。提供されたテンプレートから MVVM Light プロジェクトを作成しましたが、VS 2010 デザイナー ウィンドウで MainWindow.Xaml を表示しようとすると、System.IO.FileLoadException が発生します。テンプレートは既に System.Windows.Interactivity を参照しています。例外の詳細は次のとおりです。
System.IO.FileLoadException

System.NotSupportedException ネットワーク上の場所からアセンブリを読み込もうとしたため、以前のバージョンの .NET Framework ではアセンブリがサンドボックス化されていました。このリリースの .NET Framework では既定で CAS ポリシーが有効になっていないため、この負荷は危険な場合があります。この読み込みがアセンブリをサンドボックス化することを意図していない場合は、loadFromRemoteSources スイッチを有効にしてください。詳細については、http: //go.microsoft.com/fwlink/?LinkId=155569を参照してください。
