我已经尝试解决一个程序集绑定问题长达12个小时，但没有太大的进展。上周，我将解决方案中所有项目从EF 4.1.0.0升级到EF 4.3.1.0。今天早上，我在现有测试项目中添加了一些测试，对整个解决方案进行了清理和重新编译。所有项目都可以编译而且没有警告或错误。但是，当我在项目的任何地方调用实体框架时，我会收到以下异常：
初始化方法NutricityPPCTests.Common.DizzleProductExtensionsTests.TestSetup抛出异常。System.IO.FileLoadException: System.IO.FileLoadException:文件加载失败：Could not load file or assembly 'EntityFramework, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. 找不到文件指定的模块。 (Exception from HRESULT: 0x80131040)
我启动了Fusion程序集绑定日志查看器，并找到与异常相对应的日志条目。我已验证我的测试项目和MOMData项目都引用了正确的EF 4.3.1.0程序集。我还验证了项目文件中没有对EF 4.1.0.0的任何引用。我删除了两个项目的obj和bin目录中的内容。由于该项目已经被多次清理和重建，我的硬盘可能会在明天崩溃。

我还应该在哪里寻找旧的引用程序集？！？任何帮助都将受到欢迎并非常感激！提前感谢您的时间！
