You need to do a little bit extra to profile a service, if you get “VSPerfCLREnv was not set up correctly<\/strong>” solution is here.<\/p>\n

This “howto” has been written for a really simple service, wich you can download<\/a>. It’s tiny so you can isolate the “how do i” from the “for my service”.<\/p>\n

To quickly start do this:<\/p>\n

run “VSPerfCLREnv.cmd \/globalsampleon<\/strong>” this cmd is located in “Team Tools\\Performance Tools”(Vs2008\/vs2010) install folder, for me that is : “C:\\Program Files\\Microsoft Visual Studio 9.0\\Team Tools\\Performance Tools\\” . This will be “C:\\Program Files\\Microsoft Visual Studio 10.0\\Team Tools\\Performance Tools\\” for vs2010.<\/p>\n

If your Service starts at startup, reboot, else stop and start your service. I booted just to be sure.<\/p>\n

Open your “windows service” project in Visual Studio.<\/p>\n

When you are using my sample do this:<\/p>\n

Compile solution (this\u00a0installs\u00a0the service and starts the service, see: “build event”)<\/p>\n

Start Wizzard : Analyze > Launch Performance Wizzard , select “sampling” and finish.<\/p>\n

\"\"<\/a>\"\"<\/a>\"\"<\/a><\/p>\n

Now you can’t “Launch with Profiling” (you can’t start a service directly), you need to “Attach<\/strong>” to it, find your\u00a0service\u00a0process. Check<\/span> the “Show processes from all users<\/strong>” and “Show processes in all sessions<\/strong>“.<\/p>\n

\"\"<\/a>\"\"<\/a><\/p>\n

Run it as long as you wish until you are done. Press stop and you’ll\u00a0receive\u00a0report which you can drill down into.<\/p>\n

\"\"<\/a><\/p>\n

Now in real live applications your service might not be a hog for cpu cycles. So you might get an error that “No Data was Collected<\/strong>“.<\/p>\n
