无法加载文件或程序集 'DocumentDB.Spatial.Sql.dll' 或其依赖

Question

之一，我们有3个项目：

• 类库（目标框架4.5）
• Web应用程序（MVC）项目（目标框架4.5）
• 的Web API项目（目标框架4.5.2）

最近开始Azure的宇宙DB（文件DB驱动程序）工作。所有的实现都是在API & Web App项目中使用的类库中完成的。

显然，Web应用程序工作正常，但REST API项目抛出一个错误：

Could not load file or assembly 'file:///API\bin\DocumentDB.Spatial.Sql.dll' or one of its dependencies. The module was expected to contain an assembly manifest. 
 

 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 
 

 
Exception Details: System.BadImageFormatException: Could not load file or assembly 'file:///D:\API\bin\DocumentDB.Spatial.Sql.dll' or one of its dependencies. The module was expected to contain an assembly manifest. 
 

 
Source Error: 
 

 
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].

现在，已经尝试了以下修订（没有成功）：

1. 将API目标框架更改为4.5，重新启动 - 仍然是相同的错误。
2. 清理解决方案，重建 - 仍然是相同的错误
3. dll DocumentDb.Spatial.Sql.dll是相同的Web应用程序& Web API项目。

Answer 1

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

此路径是可疑的。您必须检查哪个模块试图加载此dll（以及为什么）

尝试启用程序集绑定日志记录并在加载解决方案时检查错误。要启用日志记录本粘贴到txt文件（和更改扩展名为.reg）：

Windows Registry Editor Version 5.00 

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

之后，支票夹C：\ FusionLog和搜索该DLL DocumentDB.Spatial.Sql.dll）
