如果一次运行一个，则单元测试通过良好，如果运行FileLoadException“；溶液中的所有测试”；

我试图对我的一些类进行单元测试，但遇到了一个问题，即单独运行测试100%都能正常工作，但如果我批量运行它们/使用"解决方案中的所有测试"选项，我的一个文件的每个测试都会失败，并返回错误：

System.IO.FileLoadException was unhandled by user code
  Message=Could not load file or assembly 'Microsoft.Practices.Prism, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
  Source=ServicesModuleTests
  FileName=Microsoft.Practices.Prism, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null

很长一段时间以来，我一直在试图找出原因，并尝试在网上搜索，但没有找到有同样问题的人。

下面是我的代码的一个快速示例：

RegistryService文件：

public class RegistryService
{
    protected ILoggerFacadeExtended _Logger { get; set; }
    protected IConnectivityService _Connectivity { get; set; }
    [ImportingConstructor]
    public RegistryService(ILoggerFacadeExtended logger, IConnectivityService connectivity)
    {
        this._Logger = logger;
        this._Connectivity = connectivity;
    }
    public string GetRegistryPath(RegistryHive hive, string path)
    {
        string registryPath = string.Format("{0}''{1}", GetRegistryHiveString(hive), path.Trim(''''));
        _Logger.DebugWithFormat("Found registry path: {0}", registryPath);
        return registryPath;
    }
    private string GetRegistryHiveString(RegistryHive hive)
    {
        switch (hive)
        {
            case RegistryHive.ClassesRoot:
                return "HKEY_CLASSES_ROOT";
            case RegistryHive.CurrentConfig:
                return "HKEY_CURRENT_CONFIG";
            case RegistryHive.CurrentUser:
                return "HKEY_CURRENT_USER";
            case RegistryHive.DynData:
                return "HKEY_DYN_DATA";
            case RegistryHive.LocalMachine:
                return "HKEY_LOCAL_MACHINE";
            case RegistryHive.PerformanceData:
                return "HKEY_PERFORMANCE_DATA";
            case RegistryHive.Users:
                return "HKEY_USERS";
        }
        throw new ArgumentOutOfRangeException("hive");
    }
}

测试文件：

private RegistryService CreateMockedRegistryService()
{
    return new RegistryService(MockRepository.GenerateMock<ILoggerFacadeExtended>(), MockRepository.GenerateMock<IConnectivityService>());
}
[TestMethod()]
public void GetRegistryPathTest_ClassesRoot()
{
    RegistryService target = CreateMockedRegistryService();
    RegistryHive hive = RegistryHive.ClassesRoot;
    string path = @"Something'SomethingElse'";
    string expected = @"HKEY_CLASSES_ROOT'Something'SomethingElse";
    string actual;
    actual = target.GetRegistryPath(hive, path);
    Assert.AreEqual(expected, actual);
}
[TestMethod()]
public void GetRegistryPathTest_CurrentConfig()
{
    RegistryService target = CreateMockedRegistryService();
    RegistryHive hive = RegistryHive.CurrentConfig;
    string path = @"Something'SomethingElse'";
    string expected = @"HKEY_CURRENT_CONFIG'Something'SomethingElse";
    string actual;
    actual = target.GetRegistryPath(hive, path);
    Assert.AreEqual(expected, actual);
}

我简化了代码，试图在不占用太多空间的情况下展示我正在做的事情。我可以一个接一个地运行这些程序，但在一起运行时会收到异常。
