我正在使用WCF测试客户端向服务发出请求,但是我收到以下错误：

Could not load file or assembly 'aDoc_Client.XmlSerializers' or one of its dependencies. The system cannot find the file specified.

我确认我已在项目属性中生成序列化程序集 – >建立.

我还使用.csproj中的代码(Generating an Xml Serialization assembly as part of my build)激活了SGEN来强制XML序列化：

<Target Name="AfterBuild" 
        DependsOnTargets="AssignTargetPaths;Compile;ResolveKeySource" 
        Inputs="$(MSBuildAllProjects);@(IntermediateAssembly)" 
        Outputs="$(OutputPath)$(_SGenDllName)">
<!-- Delete the file because I can't figure out how to force the SGen task. -->
<Delete Files="$(TargetDir)$(TargetName).XmlSerializers.dll" ContinueOnError="true" />
  <SGen BuildAssemblyName="$(TargetFileName)" 
      BuildAssemblyPath="$(OutputPath)" 
      References="@(ReferencePath)" 
      ShouldGenerateSerializer="true" 
      UseProxyTypes="false" 
      KeyContainer="$(KeyContainerName)" 
      KeyFile="$(KeyOriginatorFile)" 
      DelaySign="$(DelaySign)" 
      ToolPath="$(TargetFrameworkSDKToolsDirectory)" 
      Platform="$(Platform)">
    <Output TaskParameter="SerializationAssembly" 
          ItemName="SerializationAssembly" />
  </SGen>
</Target>

但是我得到以下错误：

There was an error reflecting type 'aDoc_Client.DocumentManagementExplicitService.OTAuthentication'.

我怀疑这可能是第一个错误的原因,但是此对象是服务引用中的对象.

Reference.cs中的Object声明如下：

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.1015")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="urn:api.ecm.opentext.com")]
public partial class OTAuthentication : object, System.ComponentModel.INotifyPropertyChanged {

    private string authenticationTokenField;

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute(Order=0)]
    public string AuthenticationToken {
        get {
            return this.authenticationTokenField;
        }
        set {
            this.authenticationTokenField = value;
            this.RaisePropertyChanged("AuthenticationToken");
        }
    }

    public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged;

    protected void RaisePropertyChanged(string propertyName) {
        System.ComponentModel.PropertyChangedEventHandler propertyChanged = this.PropertyChanged;
        if ((propertyChanged != null)) {
            propertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
        }
    }
}

我怎样才能生成MyAssembly.XmlSerializers.dll？

更新1：

在我的应用程序和服务引用之间的最后一个联系点插入try catch之后：

public string AuthenticateUser(string userName, string userPassword) {
    string output = string.Empty;

    try
       {
           output = base.Channel.AuthenticateUser(userName, userPassword);
       }
    catch(Exception ex)
       {
           output = ex.ToString();
       }

    return output;
}

返回带有异常的字符串后,我收到以下错误：

System.IO.FileNotFoundException: Could not load file or assembly 'aDoc_Client.XmlSerializers' or one of its dependencies. The system cannot find the file specified.
File name: 'aDoc_Client.XmlSerializers'

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

更新2：

使用visual studio命令提示符在Could not load MyAssembly.XmlSerializers.dll. The system cannot find the file specified中手动运行SGEN工具后,我收到以下错误：

Error: There was an error reflecting type
          'aDoc_Client.DocumentManagementExplicitService.OTAuthentication'.
  - Types 'aDoc_Client.DocumentManagementExplicitService.OTAuthentication' 
      and 'aDoc_Client.AuthenticationExplicitService.OTAuthentication' 
both use the XML type name, 'OTAuthentication', from namespace 'urn:api.ecm.opentext.com'. 
Use XML attributes to specify a unique XML name and/or namespace for the type.

If you would like more help, please type "sgen /?".

aDoc_Client.DocumentManagementExplicitService和aDoc_Client.AuthenticationExplicitService是服务引用,我需要找到一种方法来为服务引用指定新的命名空间.

更新3：

看起来很疯狂,如果不改变单行代码,有一种情况是我在调用服务时没有异常.

> IIS重置
>使用WCF测试客户端(FAILS)调用服务
>使用WCF测试客户端(FAILS)调用服务
>使用.net应用程序调用服务(OK)
>使用WCF测试客户端调用服务(OK)

这永远重复,我似乎无法理解为什么它只能在从.net应用程序首次调用后才能工作.

解决方法:

问题是WCF测试客户端版本.
