Question

过去一周，这个问题一直让我发疯。

我们将3.5解决方案迁移到4.0（使用EF4开始），这里没有大问题。我已经使用Visual Studio 2010 Final一段时间没有任何问题。

将解决方案和关联的第三方程序集迁移到.net 4.0，虽然运行时性能与3.5级相同，但启动调试程序现在大约需要2:30到3:00 ，在几台好机器上（Core i7，Core i5笔记本电脑和带有大量内存的Phenom 4x台式机）。

在3.5解决方案中，所有过程大约需要20-30秒 !!，幸运的是，如果我们在没有调试的情况下启动站点并且仅在没有问题的情况下附加调试器，并且一切似乎都没问题。< / p>

输出窗口我得到的是 4000首次异常，这似乎会减慢过程：

mscorlib.dll中出现'System.Globalization.CultureNotFoundException'类型的第一次机会异常

我已经调试了这个异常但没有结论，似乎在CultureInfo方法名称= Resx上，显然这不是一个正确的文化：

    public CultureInfo(String name, bool useUserOverride) { 
    if (name==null) {
        throw new ArgumentNullException("name",
            Environment.GetResourceString("ArgumentNull_String"));
    } 
    Contract.EndContractBlock();

    // Get our data providing record 
    this.m_cultureData = CultureData.GetCultureData(name, useUserOverride);

    if (this.m_cultureData == null)
        throw new CultureNotFoundException(
            "name", name, Environment.GetResourceString("Argument_CultureNotSupported"));

    this.m_name = this.m_cultureData.CultureName;
    this.m_isInherited = (this.GetType() != typeof(System.Globalization.CultureInfo)); 
}

这是堆栈跟踪：

有人有同样的问题吗？
任何想法如何找到根本原因此异常（堆栈跟踪不是确定的）或/和表现降解？
