WCF web服务错误：无法激活该服务，因为它不支持ASP.NET兼容性

我正在尝试创建一个restful wcf web服务。当我尝试通过客户端连接到服务时，出现以下错误：

无法激活该服务，因为它不支持ASP.NET兼容性。已为此应用程序启用ASP.NET兼容性。在web.config中关闭ASP.NET兼容模式，或将AspNetCompatibilityRequirements属性添加到RequirementsMode设置为“允许”或“必需”的服务类型中。

其他人也有问题，但他们通过更改web.config来解决。我已经实现了他们的修复，但问题仍然存在。这是我的web.config：

<system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="WebBehavior" >
           <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="MyServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="MyServiceBehavior" name="myfirstwcf">
        <endpoint address="ws" binding="basicHttpBinding" 
                  contract="Imyfirstwcf" />
        <endpoint address="ws2" binding="wsHttpBinding" 
                  contract="Imyfirstwcf" />
        <endpoint address="" behaviorConfiguration="WebBehavior" 
                  binding="webHttpBinding" 
                  contract="Imyfirstwcf" />
        <endpoint address="mex" binding="mexHttpBinding" 
                  contract="IMetadataExchange" />
      </service>
    </services>
    <serviceHostingEnvironment aspNetCompatibilityEnabled= "true"
      multipleSiteBindingsEnabled="true"  />
  </system.serviceModel>

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="false" multipleSiteBindingsEnabled="true" /> 
</system.serviceModel>

在您的主要服务上，您可以将您的服务标记为：

[AspNetCompatibilityRequirements(
        RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

从

开始，它将工作：

您已在代码中更改此行或在web.config中添加此行：

<system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="WebBehavior" >
           <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="MyServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="MyServiceBehavior" name="myfirstwcf">
        <endpoint address="ws" binding="basicHttpBinding" 
                  contract="Imyfirstwcf" />
        <endpoint address="ws2" binding="wsHttpBinding" 
                  contract="Imyfirstwcf" />
        <endpoint address="" behaviorConfiguration="WebBehavior" 
                  binding="webHttpBinding" 
                  contract="Imyfirstwcf" />
        <endpoint address="mex" binding="mexHttpBinding" 
                  contract="IMetadataExchange" />
      </service>
    </services>
    <serviceHostingEnvironment aspNetCompatibilityEnabled= "true"
      multipleSiteBindingsEnabled="true"  />
  </system.serviceModel>

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="false" multipleSiteBindingsEnabled="true" /> 
</system.serviceModel>

如果有人拥有大量服务，并且服务是使用自定义的

ServiceHostFactory

创建的，那么也可以在

CreateServiceHost

方法中设置

AspNetCompatibilityRequirementsAttribute

示例：

public class HostFactory : ServiceHostFactory
{
    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
    {
        var host = new ServiceHost(serviceType, baseAddresses);
        //other relevent code to configure host's end point etc
        if (host.Description.Behaviors.Contains(typeof(AspNetCompatibilityRequirementsAttribute)))
        {
            var compatibilityRequirementsAttribute = host.Description.Behaviors[typeof(AspNetCompatibilityRequirementsAttribute)] as AspNetCompatibilityRequirementsAttribute;
            compatibilityRequirementsAttribute.RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed;
        }
        else
        {
            host.Description.Behaviors.Add(new AspNetCompatibilityRequirementsAttribute() { RequirementsMode =AspNetCompatibilityRequirementsMode.Allowed});
        }
        return host;
    }
}

实际上，根据最新的文档，你需要做两件事

1.对于您的服务级别：

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(Namespace = "url")]
public class Service : IService
{
}

2.对于web.config

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

有效的感谢可能重复。如果其他人正在使用vb.net…语法是：我真正需要的是一个使用vb.net语法创建restful wcf的好例子，但我能找到的只是C#示例，我花时间尝试转换到vb.net。如果有人知道vb.net中的好示例代码，请让我知道，或者给我发送一个链接。在我找到这个答案之前，我花了大约12个小时试图找到“服务器没有提供有意义的回复；这可能是由于合同不匹配、会话过早关闭或内部服务器错误造成的”，并且解决了我的问题=P谢谢！当我把我的操作系统从Win7切换到Win8时，我得到了这个。甚至调试项目也不起作用。IIS8上的某些内容使得WCF服务需要此配置。谢谢你，史蒂夫！：）工作起来很有魅力。另外，别忘了在您的使用列表中添加System.ServiceModel.Activation命名空间。这解决了我的问题，更改了

aspNetCompatibilityEnabled=“false”

这对我很有效。这种方法的另一个好处是，它不需要您重新编译源代码。我更喜欢更改配置文件，而不是更改代码文件。
