XML 序列化程序抛出异常："method not found"

Question

var txnSerializer = new TxnSerializer(); //generated serializer
TextWriter writer = new StringWriter();
txnSerializer.Serialize(writer, response.ReturnValue);

抛出以下异常：

System.InvalidOperationException was unhandled by user code
  HResult=-2146233079
  Message=There was an error generating the XML document.

这是奇怪的部分：它在团队中除我以外的所有其他开发工作站上都运行良好。这是许多失败的测试之一，所有测试都因相同的错误而失败。求助！

System.MissingMethodException 几乎总是 .NET 应用程序环境不正确的症状（例如，DLL 版本不匹配）。我会尝试以下操作：

重建并重新部署整个解决方案。根据您的部署选项，您可能希望在重新部署之前删除（清理）部署文件夹中的所有现有 .DLL。当旧程序集徘徊在它们不应该存在的地方时，就会发生这种异常。重新部署后重新启动 IIS。
使用 gacutil /u DLL_NAME 从 GAC 中删除任何依赖程序集。之后重新启动 IIS。使用 gacutil /if "<path to the assembly .dll file>"
