WCF で非常に奇妙な問題が発生しています。ソリューションに 2 つのプロジェクトがあり、それぞれがセルフホステッド WCF サービスを開始します。
プロジェクト 1:
myService = new ServiceHost(typeof(MyService1));
これは正常に実行されます。ただし、次を含む2番目のプロジェクトを実行しようとすると:
meService = new ServiceHost(typeof(MyOtherService));
私は例外を受け取ります：
FileNotFoundException
Could not load file or assembly 'System.ServiceModel' or one of its dependencies.
The system cannot find the file specified.":"System.ServiceModel

本当に奇妙な部分は、デバッガーで、この例外が発生したときに、Visual Studio の「QuickWatch」に移動して次のように入力できることです。
new MyOtherService() // returns new instance properly
new ServiceHost() // returns new instance properly
new ServiceHost(typeof(MyOtherService)) // throws exception, same as above.
デバッグ中に SysInternals File System Watcher を実行しようとしましたが、devenv.exe が .pdb ファイルを追跡してスタック トレースを生成しようとする以外に、'FileNotFound' エラーは表示されません。
誰が何を見るべきかについて他のアイデアを持っていますか?
更新 #1
プロセスのフュージョン ログを調べたところ、何かおかしなことが起こっているようです。System.ServiceModel の 2 つのログ エントリが連続しています。

System.ServiceModel を 2 回、GAC ではなくローカル アプリ ディレクトリから 1 回ロードしようとしているようです。よくわかりません...
