程序集绑定旧引用异常

Question

我一直试图解决过去12小时的装配绑定问题,运气不大.上周,我已经将解决​​方案中的所有项目从EF 4.1.0.0升级到EF 4.3.1.0.我今天早上在现有的测试项目中添加了一些测试,清理并重新编译了解决方案.所有项目都在编译时没有任何警告或错误.在我的实体框架调用项目中的任何地方,我收到以下异常:

初始化方法NutricityPPCTests.Common.DizzleProductExtensionsTests.TestSetup抛出异常.System.IO.FileLoadException:System.IO.FileLoadException:无法加载文件或程序集'EntityFramework,Version = 4.1.0.0,Culture = neutral,PublicKeyToken = b77a5c561934e089'或其依赖项之一.定位的程序集的清单定义与程序集引用不匹配.(HRESULT异常:0x80131040).

我启动了融合程序集绑定日志查看器,并找到了与异常对应的日志条目.我已经验证我的测试项目,MOMData项目都引用了正确的EF4.3.1.0程序集.我确认项目文件中没有引用EF 4.1.0.0.我删除了两个项目中obj和bin目录的内容.该项目已经清理和重建了很多次,我的硬盘可能会在明天发布.

我还应该在哪里寻找旧的引用程序集？!？欢迎任何帮助,非常感谢!在此先感谢您的时间!

将以下内容添加到web.config文件中:

<runtime>
<assemblyBinding>
        <dependentAssembly>
          <assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" culture="neutral" />
          <bindingRedirect oldVersion="0.0.0.0-4.3.1.0" newVersion="4.3.1.0" />
        </dependentAssembly>
   </assemblyBinding>
</runtime>

我有同样的错误。我的解决方案中的大多数项目都引用了 Entity Framework 4.3.0.0 dll，但是当我检查解决方案中所有项目的引用时，我发现一些项目引用了 Entity Framework 4.1.0.0 dll。删除它们并用对 Entity Framework 4.3.0.0 dll 的新引用替换它们可以解决该问题。
