今天在项目内一个Winform增加控件后，无法打开，抛如下异常。
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object.

经查抄，堕落代码在..Designer.cs:line 2547。此代码是VisualStudio自动生成的，没理由堕落。
后来经同事提醒，打开TestForm.resx文件时，VisualStudio提示有反复，，本来我新控件后，对控件重定名了（只改了名字的巨细写），这样导致了TestForm.resx呈现巨细写名称差此外项，断根废弃项后，WinForm正常。
这应该是VisualStudio的Bug.
WinForm的.Designer.cs代码内抛反射异常
