Cannot start service from the command line or a debugger

Cannot start service from the command line or a debugger.  A Windows Service must first be installed (using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool or the NET START command

When you run windows service debug mode from VS, i got above error.

Solution:

OOTB code:

 static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        static void Main()
        {
             ServiceBase[] ServicesToRun;
            ServicesToRun = new ServiceBase[]
            {
                new Scheduler()
            };
            ServiceBase.Run(ServicesToRun);    

        }
    }

Change to:


 static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        static void Main()
        {
            //ServiceBase[] ServicesToRun;
            //ServicesToRun = new ServiceBase[]
            //{              
            //    new Scheduler()
            //};
            //ServiceBase.Run(ServicesToRun);


            var myService = new Scheduler();
            if (Environment.UserInteractive)
            {
                MtProject.Scheduler objScheduler = new Scheduler();
                objScheduler.GetData();
            }
            else
            {
                var servicesToRun = new ServiceBase[] { myService };
                ServiceBase.Run(servicesToRun);
            }

        }
    }

Process with an ID #### is not running in visual studio

Solution:
Close VS.
Navigate to the folder of the solution and delete the hidden .vs folder.
Restart VS.
Run the application

An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll

An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll

Additional information: String was not recognized as a valid DateTime.

I got above error, but same code was working from another system.

My config:
    <add key="sDate" value="16-02-2012 11:13:23"/>

Root cause: The system which i am running the code is having local date format as DD/M/YYYY
But the my input is having MM/DD/YYYY

Solution:
Option 1: Change sDate from    <add key="sDate" value="16-02-2012 11:13:23"/> Value to
<add key="sDate" value="02-16-2012 11:13:23"/>

Option 2: Change system date format to MM/DD/YYYY
