NHibernate を実装するプロジェクトがあります。プロジェクトは Visual Studio 2010 を搭載したマシンで正常に動作します。そのプロジェクトを Visual Studio 2012 にインポートすると、 NHibernate.MappingExceptionが発生します。

.hbm.xml は埋め込みリソースとして設定され、出力ディレクトリへのコピーはすべての .hbm.xml ファイルに対して常にコピーとして設定されます。

プロジェクトはVS 2010で実行されるため、マッピングの問題がどのように発生するかわかりません。

必要なすべての情報を含む内部例外は次のとおりです。

エラー: NHibernate.MappingException: マッピング ドキュメントをコンパイルできませんでした: HibernateExample.Domain.Dairy.hbm.xml ---> NHibernate.MappingException: 永続クラス HibernateExample.Domain.Dairy、HibernateExample が見つかりません ---> System.TypeLoadException: 可能性がありますアセンブリ 'HibernateExample, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' からタイプ 'HibernateExample.Domain.Dairy' をロードしません。

Factory 構成中に、NHibernate は 3 番目 (質問の上から) を含むすべての埋め込みリソースを読み取ります。

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" 
  assembly="HibernateExample" 
  namespace="HibernateExample.Domain" >
  <class name="Dairy" table="Products">

したがって、問題は明確です。利用可能なクラスがありませHibernateExample.Domain.Dairyん (デプロイされていない、タイプミス、またはネームスペースが正しくありません)。良いニュースまたはメッセージは、マッピングが見つかり、解析されたことです...

アプリケーションがマップされたクラスにアクセスできることを確認してください
