Question

When I perform a command on the client, it waits for a response. I know this command will take a long time but the default timeout seems to be about 1 minute. Every time I invoke the command from the client I get this error:

System.TimeoutException was unhandled
  HResult=-2146233083
  Message=The request channel timed out while waiting for a reply after 00:00:59.9809981. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout.

The HTTP request to 'http://localhost:9999/CommandService.svc' has exceeded the allotted timeout of 00:00:59.9870000. The time allotted to this operation may have been a portion of a longer timeout.

Here is the app.config in the client.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_CommandService" />
                <binding name="BasicHttpBinding_QueryService" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:9999/CommandService.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_CommandService"
                contract="CommandServices.CommandService" name="BasicHttpBinding_CommandService" />
            <endpoint address="http://localhost:9999/QueryService.svc" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_QueryService" contract="QueryServices.QueryService"
                name="BasicHttpBinding_QueryService"/>
        </client>
    </system.serviceModel>
</configuration>

…and here is the web.config of the WCF service.

<?xml version="1.0"?>
<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>

  <system.serviceModel>

      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="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>
    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <!--
        To browse web app root directory during debugging, set the value below to true.
        Set to false before deployment to avoid disclosing web app folder information.
      -->
    <directoryBrowse enabled="true"/>
  </system.webServer>
  <connectionStrings>
    <add name="MainframeEntities" connectionString="metadata=res://*/MainframeEntities.csdl|res://*/MainframeEntities.ssdl|res://*/MainframeEntities.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=IT-DEV;initial catalog=Mainframe;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>

</configuration>

I’m not sure where to change the timing. Thanks.
