mscorlib.XmlSerializers.DLL的FileNotFoundException,它不存在

我正在使用XmlSerializer来反序列化mscorelib.dll中的特定类型

XmlSerializer ser = new XmlSerializer( typeof( [.Net type in System] ) );
return ([.Net type in System]) ser.Deserialize( new StringReader( xmlValue ) );

这会FileNotFoundException在加载程序集时抛出一个catch :

"无法加载文件或程序集'mscorlib.XmlSerializers,Version = 2.0.0.0,Culture = neutral,PublicKeyToken = b77a5c561934e089'或其中一个依赖项.系统找不到指定的文件."

据我所知,没有mscorlib.XmlSerializers.DLL,我认为.Net的自动生成的DLL名称正在寻找序列化程序.

在编译优化序列化时,您可以选择创建myApplication.XmlSerializers.DLL,因此我认为这是框架检查它的一部分.

问题是,这似乎导致加载应用程序的延迟 - 此时似乎挂起了几秒钟.

任何想法如何避免或加快它？
