visual studio 2010 - VS2010 Load Testing: How can I perform custom action that is run once prior to each load test

Question

Basically, I need to restart particular service prior to each load test being run and there is no problem with the restart itself. I've researched for a while and haven't found a way to put some action or script or just another load test, so that I can be sure it is performed before each load test and only one time per load test.

Any ideas regarding how to make it behave this way are appreciated.

Create a LoadTest Plugin and use the LoadTestStarting event to call a method that restarts your service.

public class Plugin : ILoadTestPlugin
{
    private LoadTest _loadTest;

    public void Initialize(LoadTest loadTest)
    {
        _loadTest = loadTest;
        _loadTest.LoadTestStarting += new System.EventHandler(loadTest_LoadTestStarting);
        _loadTest.LoadTestFinished += new System.EventHandler(loadTest_LoadTestFinished);
    }

    void loadTest_LoadTestStarting(object sender, System.EventArgs e)
    {
        // Restart your service
    }

    void loadTest_LoadTestFinished(object sender, System.EventArgs e)
    {
    }
}

Then in the Load Test Editor right click on the root and select Add Load Test Plug-in... to add the Plug-In to your Load Test.
