WCF 测试客户端：添加服务失败。服务元数据可能无法访问。确保您的服务正在运行并公开元数据
我目前正在尝试使同步框架示例正常工作： 示例
解决方案编译时没有任何错误或警告。
但是当我按 F5 时，WCF 测试客户端启动并抛出以下错误。
本地\临时\测试客户端 项目\10.0\5b6aab8a-6629-4a12-87c2-e9e75ba9c1e4\Client.cs(379,13)： 错误CS0246：找不到类型或命名空间名称“架构” （您是否缺少 using 指令或程序集引用？）
下面是来自 Client.cs 的代码，上面的错误正在引用它，
/// <remarks/>

public partial class SyncIdFormatGroup
{
private schema schemaField;
private System.Xml.XmlElement anyField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute(Namespace="http://www.w3.org/2001/XMLSchema", Order=0)]
public schema schema
{

set { this.schemaField = value; }
}
/// <remarks/>
[System.Xml.Serialization.XmlAnyElementAttribute(Order=1)]
public System.Xml.XmlElement Any
{
get { return this.anyField; }
set { this.anyField = value; }
}
}
如果有人可以帮助我解决该问题，那就太好了。
I am currently trying to get the sync framework sample working: sample
The solution compiles with out any error or warning.
But when I hit F5 the WCF Test Client launches and throws the following error.
Local\Temp\Test Client
Projects\10.0\5b6aab8a-6629-4a12-87c2-e9e75ba9c1e4\Client.cs(379,13) :
error CS0246: The type or namespace name 'schema' could not be found
(are you missing a using directive or an assembly reference?)
Below is the code from Client.cs that the above error is referencing
/// <remarks/>

[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]

public partial class SyncIdFormatGroup
{
private schema schemaField;
private System.Xml.XmlElement anyField;
/// <remarks/>

public schema schema

set { this.schemaField = value; }
}
/// <remarks/>
[System.Xml.Serialization.XmlAnyElementAttribute(Order=1)]
public System.Xml.XmlElement Any
{
get { return this.anyField; }
set { this.anyField = value; }
}
}
It would be great if some one could help me with the problem.

找到了解决方案好吧，花了很多时间我破解了它。由于某种原因，如果我将示例作为控制台应用程序运行，它就可以正常工作。但是当我使用 WCFTestClient 时，我遇到了错误。如果我从合同中删除
[ServiceKnownType(typeof(SyncIdFormatGroup))]，它将在 WCFTestClient 中运行。希望对某人有帮助。Found the solution Ok, after spending lot of time I cracked it. For some reason if I run the sample as console app it just works fine. But the moment I use WCFTestClient I was getting errors. If I remove the
[ServiceKnownType(typeof(SyncIdFormatGroup))]from the contract it works in WCFTestClient. Hope that helps someone.您是否在服务中启用了 mex（元数据交换）端点？
Have you enabled a mex (metadata exchange) endpoint in your service?
阅读本页末尾的注释：
注意：如果您使用 Visual Studio 2010 编译这些示例，则首先需要删除对 Sync Framework 程序集的引用，然后将程序集引用重新添加到项目中。否则，您将看到“找不到类型或命名空间名称”编译错误。

Read the note at the end of the page:
Note: If you use Visual Studio 2010 to compile these samples, you will first need to remove references to the Sync Framework assemblies and then re-add the assembly references to the projects. Otherwise, you will see "type or namespace name could not be found" compilation errors.
