添加程序集引用时的端点?

我有一个使用对类库的引用的WCF服务。该库中的类可以执行与数据库交互等操作。我正在通过浏览器使用restful调用来测试我的服务(编译没有错误),它只显示一个简单地说“Endpoint not found。”的页面。我假设这与库引用连接字符串和appsettings等(我通常必须包含在使用此库的应用程序中)这一事实有关。所以我找不到的是如何正确配置wcf服务以使用此库。我尝试简单地将连接字符串和appsetings添加到wcf web.config,但这似乎没有帮助。我觉得这只是通过服务的端点部分添加对库的引用。但我迷失在那里。任何帮助表示赞赏。感谢

<system.serviceModel>
    <services>
      <service name="RestService.RestServiceImpl" behaviorConfiguration="ServiceBehavior">
        <endpoint address="" binding="webHttpBinding" contract="RestService.IRestServiceImpl" behaviorConfiguration="web">

        </endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name ="ServiceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

更新: 运行跟踪,这是抛出异常的堆栈跟踪:

好的,所以我让它运转了。它似乎是主机地址的问题。我将项目重新创建为服务库而不是服务应用程序,我注意到默认配置中有几个新字段。其中一个是主持人。当我设置基地址时,一切都开始工作只是hunkydory。这是配置:

<system.serviceModel>
<services>
  <service name="ServiceWithLibraryTest.UtiService">
    <endpoint address="" binding="webHttpBinding" contract="ServiceWithLibraryTest.IUtiService" behaviorConfiguration="web" />        
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8732/ServiceWithLibraryTest/UtiService/"/>
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehavior">
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="False"/>
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp/>
    </behavior>
  </endpointBehaviors>
</behaviors>

我对WCF不熟悉,据我所知,配置不断成为一个令人头疼的问题是臭名昭着的。我仍在努力绕过端点,但我开始更好地理解端点是如何暴露服务和行为的方式。当然,休息服务会为此添加一个全新的层。我很欣赏这些想法:)
