ServiceStack サービス (現時点では HTTP リスナーを使用してスタンドアロンで実行) に対して POST および PUT 要求を行うと、要求が機能することがあり、クライアント (HTTPie) がハングすることがあります。しばらくすると、Visual Studio の [出力] ウィンドウにいくつかの情報が表示されます:-
A first chance exception of type 'System.Net.HttpListenerException' occurred in System.dll
A first chance exception of type 'System.Runtime.Serialization.SerializationException' occurred in ServiceStack.dll
A first chance exception of type 'System.Net.HttpListenerException' occurred in System.dll
A first chance exception of type 'System.Net.HttpListenerException' occurred in ServiceStack.dll
A first chance exception of type 'System.Net.HttpListenerException' occurred in ServiceStack.dll
A first chance exception of type 'System.Runtime.Serialization.SerializationException' occurred in ServiceStack.dll
A first chance exception of type 'System.ObjectDisposedException' occurred in System.dll
ServiceStack で組み込みのロギングを有効にすると、詳細が表示されました:-

私は次のようなテストリクエストを作成しています:-
http --json post "http://localhost:1337/countries/" DefaultHouse_Id=2 Name=Denmark
この正確な試みは、うまくいく場合もあれば失敗する場合もあります。NuGet の最新の ServiceStack を .NET4 と VS 2010 で使用しています。リクエストが自分のコードにまったく到達していないようです。
これを引き起こす原因、またはデバッグ方法を知っている人はいますか?
編集:それが関連しているかどうかはわかりませんが、時々これも取得します:-
