无法加载文件或程序集'Microsoft.Practices.EnterpriseLibrary.Caching

Question

在我的 Windows 服务项目中，我参考了 Enterprise Library Caching 5.0.505，但在服务启动时出现以下错误

Service cannot be started. System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary.Caching, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
    File name: 'Microsoft.Practices.EnterpriseLibrary.Caching, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

Answer 1

当引用的程序集与 bin 文件夹中的程序集不匹配时，就会出现这种情况。

尝试将此添加到您的 .config 文件中：

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Microsoft.Practices.EnterpriseLibrary.Caching" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-5.0.505.0" newVersion="5.0.505.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>
