无法在使用WCF web服务时将PDB文件复制到另一个目录

我有一个WCF Web服务，有一个方法返回传感器列表。当我想在调试模式下的控制台应用程序中使用此web服务时，我得到了这两个错误:

Could not copy "obj'Debug'ConsumeHelper.pdb" to "bin'Debug'ConsumeHelper.pdb". Exceeded retry count of 10. Failed.  ConsumeHelper

和

Unable to copy file "obj'Debug'ConsumeHelper.pdb" to "bin'Debug'ConsumeHelper.pdb". The process cannot access the file 'bin'Debug'ConsumeHelper.pdb' because it is being used by another process. ConsumeHelper

我还添加了如下所示的消费者方法。

        SensorServiceClient client = 
                    new SensorServiceClient("WebHttpBinding_ISensorService");
        Sensor[] sensor = client.getAllSensors("true");  
        Console.WriteLine("Sensor name is "  + sensor[0].Name);
        Console.ReadLine();

那么，谁能给我一个解决方案?谢谢大家。
