Window service onstart event not fired

See more:

.NET4.6

In my Windows Service project, the project looks to be started but actually not. A piece of related code is below:

ServiceBase[] ServicesToRun;
ServicesToRun = new ServiceBase[] {  new Service1() };
g.Write2Log(g.logFolder, " WinService - PhotoFile: ServicesToRun before start  " + DateTime.Now);
try {
    ServiceBase.Run(ServicesToRun);
    g.Write2Log(g.logFolder, " WinService - PhotoFile: ServicesToRun after start  " + DateTime.Now);
} catch (Exception ex) {
    g.Write2Log(g.logFolder, "ServicesToRun can't be launched - Exception: " + ex.Message + "  " + DateTime.Now);
}

In my log file, the "ServicesToRun before start" message displays but the
"ServicesToRun after start" never displays. It means the
ServicesToRun = new ServiceBase[] { new Service1() }
is actually not called, on OnStart() event is not fired.

I checked on "Allow service to interact with desktop", but the problem still exists. What else should do for this bug? Thanks.

What I have tried:

Window Service actually not started properly
