无法在.NET 4 MVC 4应用程序中加载文件或程序集System,Version = 2.0.5.0

Question

一直在寻找年龄,找不到任何有用的东西.这是我得到的例外:

Could not load file or assembly 'System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047) 

Exception Details: System.IO.FileLoadException: Could not load file or assembly 'System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)

Stack Trace: 

[FileLoadException: Could not load file or assembly 'System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)]

StructureMap.ObjectFactory.Initialize(Action`1 action) in c:\BuildAgent\work\996e173a8ceccdca\src\StructureMap\ObjectFactory.cs:47

此应用程序在测试服务器上正常工作,但在生产服务器上抛出此异常.如您所见,StructureMap代码是导致异常的原因.

我不得不将此应用程序从4.5转换为.NET 4,因为生产服务器上没有安装4.5.转换后,应用程序仍可在我的本地计算机和测试服务器上正常运行.

我已经为系统程序集将Copy Local设置为True,但由于引用的版本是4.0.0.0而不是2.0.5.0,所以我没有区别.

如果需要更多信息,请告诉我.您可能提供的任何帮助表示赞赏.

确保修补了.NET框架.Microsoft向.NET发布了补丁程序,以允许可移植类库正确地找到适当的运行时(KB2468871).如果您看到上述异常(或类似内容),则表示您缺少最新的.NET框架补丁.
