Question

有人能告诉我将WCF服务库作为Windows服务托管的方法吗？我试图遵循各种链接，但总是得到一些或其他错误。服务启动或立即停止或客户端无法访问Windows上托管的服务..我使用简单的WPF应用程序作为客户端。

也可以有人告诉我端点地址和基地址之间的区别以及托管WCF作为Windows服务时应该设置的内容

WCF服务的App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <connectionStrings>
    <add name="mysqlconnection" connectionString="Initial catalog=calculator; data source=10.2.108.251; User Id=sa; Password=abc@123"/>
  </connectionStrings>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <!-- When deploying the service library project, the content of the config file must be added to the host's 
  app.config file. System.Configuration does not support config files for libraries. -->
  <system.serviceModel>
    <services>
      <service name="Calculator1.CalculatorService1" behaviorConfiguration="Calculator1.BasicCalculator">
        <endpoint address="" binding="wsHttpBinding" contract="Calculator1.ICalculator1">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8732/Design_Time_Addresses/Calculator1/Service1/" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Calculator1.BasicCalculator">
          <!-- To avoid disclosing metadata information, 
          set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="True"/>
          <!-- To receive exception details in faults for debugging purposes, 
          set the value below to true.  Set to false before deployment 
          to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

</configuration>

我使用SvcUtil.exe生成的app.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>

                    </security>
                </binding>

例如，如果您可以将服务作为控制台应用程序托管，则从该应用程序app.config文件中获取服务配置，并将其复制到服务的app.config文件中。

从应用程序或服务托管WCF服务之间没有任何区别。

话虽这么说，服务不会继续运行，除非你告诉它做某事。从技术上讲：必须有一些循环（理想情况下是计时器或线程）才能使服务保持活跃状态。如果您没有，服务将立即开始和停止。

啊哈！从你的问题的编辑中，有一件事变得很明显：你用app.config覆盖了代码中完成的东西的配置。您需要决定一种方式：通过app.config文件（我推荐）或通过代码执行所有操作。

托管WCF服务作为WindowsService？
