带有SQL表的WCF - 公开元数据

标签: sql wcf metadata

我开发了一个小型WCF服务,它从表中获取所有记录。它看起来像是:

IService1.cs

[ServiceContract]
public interface IService1
{
    List<badanieCis> GetRecords();
}

Service1.svc.cs

public List<badanieCis> GetRecords()
{
   przychodniaEntities dataContext = new przychodniaEntities();
   return dataContext.badanieCis.ToList();
}

我收到一条消息:无法添加服务。可能无法访问服务元数据。确保您的服务正在运行并公开元数据

我在一些研究之后做的是改变svc文件中的标记:

<%@ ServiceHost Language="C#" Debug="true"
    Service="Harvesting.Service.HarvestingService" CodeBehind="Service1.svc.cs" %>

但仍然没有。

我的web.config文件:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0">
      <assemblies>
        <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
      </assemblies>
    </compilation>

    <add name="przychodniaEntities" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=DAREK-PC\SQLExpress;initial catalog=przychodnia;integrated security=True;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>
</configuration>

您在配置文件中缺少服务定义。你需要这样的东西:

<services>
  <service behaviorConfiguration="..." name="Service1 with namespace">
    <endpoint address="..." name="..." binding="wsHttpBinding" bindingConfiguration="...." contract="IService1 with unterface" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
 <services>
 ...
