WPF 4の部分信頼

Question

WPF 4（.NET 4）で新しいプロジェクトを開始し、xbapモードで実行できるかどうかを確認しようとしています。 .NET 4で利用できる新しいモードでアプリケーションを完全信頼で実行する必要があります。このモードでは、完全信頼アプリケーションを実行するかどうかをエンドユーザーに尋ねます。

「セキュリティ」を設定しました;モードを「完全信頼」に切り替えますアプリケーション、そしてそれはうまく構築されます。実行すると例外がスローされ、IEエラーメッセージに次のエラーが表示されます。

それを回避する方法はありますか？

The action that failed was:
Demand
The type of the first permission that failed was:
System.Security.Permissions.FileIOPermission

完全信頼の自己署名xbapアプリケーションを実行することがわかった唯一の方法は、クライアントのマシンに証明書を追加する（ほとんどの場合不可能な場合があります）か、サイトのURLを信頼できるリストに追加することですサイト。後者が最も便利で、信頼できる機関によって発行された有効な証明書によって署名されているかのようにアプリケーションが実行されることがわかりました。

これは.NET 4.0でのみ可能であり、WPF / .NETの以前のバージョンでは機能しないことに注意してください
