.NET 4.5中的序列化异常

Question

我打电话时收到这个堆栈跟踪:

XslCompiledTransform.Transform(XmlDocument.DocumentElement.CreateNavigator(), null, StringWriter)


System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Runtime.Serialization.SerializationException: Type is not resolved for member --MyProject stuff
   at System.AppDomain.GetHostEvidence(Type type)

   at System.Xml.Xsl.XslCompiledTransform.Load(XmlReader stylesheet, XsltSettings settings, XmlResolver stylesheetResolver)
   at MyProject

XslCompiledTransform对象将使用GetManifestResourceStream的XmlReader加载到嵌入的.xslt文件中,但我已确认它正确获取该信息.

我已经看了很多,并把它缩小到这个电话,但我不知道从哪里开始.还有其他人经历过这个吗？

这是在Windows 8机器上,但我在server2008r2操作系统上体验过它

Answer 1

我遇到与.NET 4.5相同的错误.我只在使用nunit 2.6+时看到错误.当您在子AppDomain中初始化XmlSerializer时,似乎会发生这种情况,其中对象存储在CallContext中.如果将ApplicationBase(bin-path)设置为sub-AppDomain中的不同内容,则无法解析CallContext中对象的类型.您可以在Fusion Log Viewer中看到程序集绑定错误:http://msdn.microsoft.com/en-us/library/e74a18c4.aspx

在我的情况下,如果我将其中包含类型的程序集复制到nunits bin-path,则错误就会消失.这当然不是一个可行的解决方案.

您是否找到了错误的根本原因？

编辑:我通过让类型继承MarshalByRefObject来修复它:在将Project从vs2005迁移到vs2010(MSTest)之后,在UnitTest中无法解析类型

编辑2:替代修复是在失败的代码之前调用System.Configuration.ConfigurationManager.GetSection("dummy").
