为什么需要“优化代码”将开启我的程序没有崩溃运行？

Question

我得到这个WPF应用程序，当我试图运行在调试模式下，将前往Windows1.xml前程序崩溃。后来我试着在发布模式下运行，它会成功运行。我把范围缩小到这一点，我需要打开“优化代码”，它的工作。

注意：断点，步入从调试，并停止在抛出异常不工作

修改唯一的例外是WPF（非常流行＆没有帮助的）一般异常：

{“无法创建的‘主’在组件定义的实例‘VCELL2，版本= 1.0.0.0，文化=中性公钥=空’。异常已被调用的目标抛出。错误标记文件 'Window1.xaml' 行1点的位置9。“}   来源= “PresentationFramework”   LineNumber上= 1   LinePosition = 9

修改内 - 内部异常： { “指定的模块找不到（从HRESULT异常：0x8007007E）。”：空}

您需要提供更多的信息。什么是例外？这可能是一种在运行时无法分辨所引用。如果不使用的代码，优化器可能只是从JIT忽略它，而在调试模式下，它可以触发型负载例外。谁知道，虽然。没有更多的信息这将会是不可能告诉。

修改以响应你的问题的更新，好像有一个名为主要类型是其实例构造函数或静态构造函数抛出异常。它也可能是已触发这个字段初始值。如果您可以捕获该异常，检查它的InnerException这TargetInvocationExceptions通常含有。这会给你更多的信息。

修改您已经表明，内部异常是一个集加载问题，而这正是我最初想通。所以你的地方缺少一个参考。特别是，你可能引用一个DLL，它反过来引用其他DLL不能定位。你需要弄清楚哪些组件不能得到解决。您可以使用 fuslogvw.exe 工具查看组件绑定错误。
