采用vs2015版后，出现CS0618错误 'DiagnosticMonitor' is obsolete: 'This API is deprecated.'

Question

将原vs2012编制的程序，升级至vs2015版本后。

系统就报“CS0618  'DiagnosticMonitor' is obsolete: 'This API is deprecated.'”

vs2012版本的调用时，程序集是可以正常运行的。

程序集如下：

 public override bool OnStart()
        {
            // Set the maximum number of concurrent connections
            ServicePointManager.DefaultConnectionLimit = 12;

            DiagnosticMonitor.Start("DiagnosticsConnectionString");

            // For information on handling configuration changes
            // see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.
            RoleEnvironment.Changing += RoleEnvironmentChanging;

            Microsoft.WindowsAzure.CloudStorageAccount.SetConfigurationSettingPublisher((configName, configSetter) =>
            {
                configSetter(Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.GetConfigurationSettingValue(configName));
            });

            return base.OnStart();
        }

请各位大虾，帮忙指导一下！谢谢！
