ファイルまたはアセンブリをロードできませんでした「DocumentDB.Spatial.Sql.dll」またはその依存関係の1つ

Question

我々は3つのプロジェクトがあります。

• クラスライブラリ（ターゲットフレームワーク4.5）
• Webアプリケーション（MVC）プロジェクト（ターゲットフレームワーク4.5）
• ウェブAPIプロジェクト（ターゲットフレームワーク4.5.2）

は最近AzureのコスモスDB（文書DBドライバ）で働き始めました。すべての実装は、API & Web Appプロジェクトで使用されるクラスライブラリで行われます。

どうやら、Webアプリケーションが正常に動作しますが、REST APIプロジェクトがエラーをスローします。

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. 
 

 
Assembly Load Trace: The following information can be helpful to determine why the assembly 'file:///D:\API\bin\DocumentDB.Spatial.Sql.dll' could not be loaded. 
 

 

 
WRN: Assembly binding logging is turned OFF. 
 
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. 
 
Note: There is some performance penalty associated with assembly bind failure logging. 
 
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

、（なしの成功と）以下の修正を試してみました：

1. APIターゲットフレームワークを4.5に変更し、再起動しました - それでも同じエラーです。
2. リビルド - まだ同じエラー
3. dll DocumentDb.Spatial.Sql.dllは、Webアプリケーション& Web APIプロジェクトと同じです。

Answer 1

Could not load file or assembly 'file:///API\bin\DocumentDB.Spatial.Sql.dll'

このパスは疑わしいです。どのDLLがこのDLLをロードしようとしているのかを確認する必要があります（理由とその理由）

解決方法を読み込み中にエラーがないかどうかを確認してください。ロギングを有効（.REGすると変更拡張）txtファイルにこれを貼り付けるには：その後

Windows Registry Editor Version 5.00 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion] 
"ForceLog"=dword:00000001 
"LogFailures"=dword:00000001 
"LogResourceBinds"=dword:00000001 
"LogPath"="C:\\FusionLog" 

を、フォルダCチェック：）\ FusionLogをし、このDLLのDocumentDB.Spatial.Sql.dllを検索
