WCF Metadata publishing for this service is currently disabled + Content Type error
提问by KevinDeus
That Metadata error is what I get when I browse to the service in a browser. I am not consuming it with a client
当我在浏览器中浏览到服务时，我得到了元数据错误。我没有和客户一起消费
and Yes.. I added <serviceMetadata httpGetEnabled="True"/>, and I have a mex endpoint defined
是的..我添加了<serviceMetadata httpGetEnabled="True"/>，我定义了一个 mex 端点
but it still won't work..
但它仍然不起作用..
So I created a barebones service to host on IIS7. Fresh install of Windows 7 and VS2010.
所以我创建了一个准系统服务来托管在 IIS7 上。全新安装 Windows 7 和 VS2010。
I had followed the instructions of this page to the letter:
我已按照此页面的说明进行操作：

I'm convinced that this has to be some sort of configuration issue with IIS7 but and not sure. Here's my service setup:
我确信这一定是 IIS7 的某种配置问题，但不确定。这是我的服务设置：
EDIT:

I tried accessing the service with svcutil and got the following error:
我尝试使用 svcutil 访问该服务并收到以下错误：
The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..
it also says: The HTML document does not contain Web service discovery information.
它还说： The HTML document does not contain Web service discovery information.
not sure how to resolve it, however..

Your code and config seems fine - except for one little point:
您的代码和配置似乎很好 - 除了一点点：
In your <service>tag, you have defined a name that doesn't seem to correspond to the class that actually implements your service:
在您的<service>标签中，您定义了一个似乎与实际实现您的服务的类不对应的名称：
<service name="DestructionServices.Destro" ......>
**************************
but your class is:
但你的班级是：
namespace DestructionServices
{
.....
public class TacticalNukeSVC : INukeInterface
{
Those names need to match! The name=attribute on the <service>tag in config must beexactly what your service class is called - fully qualified, including namespace - so in your case here, it should be:
这些名字需要匹配！在name=该属性<service>的配置标签必须什么服务类被称为-完全合格，其中包括命名空间-所以你的情况在这里，它应该是：
<service name="DestructionServices.TacticalNukeSVC" ......>

Previously working WCF with nice~ settings stopped working and shows - error- Metadata publishing for this service is currently disabled.
以前使用 nice~ 设置工作的 WCF 停止工作并显示 - 错误 - 此服务的元数据发布当前已禁用。
THOUGH MEX Settings are perfect, still WCF shows above error, reason: The virtual directory created from VS IDE IS NOT Created, though it gives "success" message..
虽然 MEX 设置是完美的，但 WCF 仍然显示上述错误，原因：未创建从 VS IDE 创建的虚拟目录，尽管它给出了“成功”消息..
Just Create Virtual Directory in IIS manually , Bingo error is resolved.
只需在 IIS 中手动创建虚拟目录，Bingo 错误已解决。
Hope it helps!
希望能帮助到你！

I had another issue. I have an IIS asmx application, and inside I've placed a subfolder with svc. Configured it properly, but it didn't give me the metadata until I found this in web.config in parentdirectory:
我有另一个问题。我有一个 IIS asmx 应用程序，在里面我已经放置了一个带有 svc 的子文件夹。正确配置了它，但直到我在父目录中的 web.config 中找到它之前它没有给我元数据：
<system.web>
<webServices>
<soapExtensionTypes>
<add type="SPFWebService.SPFWebServiceExtension,App_Code" priority="1" group="0" />
</soapExtensionTypes>
</webServices>
</system.web>
Fixed it by removing my new service to a separate directory.
通过将我的新服务删除到单独的目录来修复它。

if you have a class with no default constructor an another constructors , then add an empty default constructor , I had the same issue and i resolved it by this .
如果你有一个没有默认构造函数和另一个构造函数的类，然后添加一个空的默认构造函数，我有同样的问题，我通过这个解决了它。

I had a similar issue. For anyone that might come across this later. My problem was that my service interface did not have the [ServiceContract] DataAnnotation
我有一个类似的问题。对于以后可能会遇到此问题的任何人。我的问题是我的服务接口没有 [ServiceContract] DataAnnotation
[ServiceContract] //<--This was missing
public interface IServiceInterface
{
[OperationContract]
void Foo(Bar bar)
//...
}

Encountered a similar issue. I had the wrong namespace in my service tag in web.config as against the namespace for the service class in the svc file.
遇到了类似的问题。我在 web.config 中的服务标记中的命名空间与 svc 文件中服务类的命名空间相反。
web.config
网页配置
< service name="X.Y.Z.ContentService" behaviorConfiguration="XServiceBehavior">
svc file
.svc 文件
<%@ ServiceHost Language="C#" Debug="true" Service="X.Y.A.ContentService" %>
As seen above, service tag in web.config had namespace X.Y.Z where the svc file had X.Y.A.
如上所示，web.config 中的服务标签具有命名空间 XYZ，其中 svc 文件具有 XYA
