this question has answer here:

long story short built console application worked fine, told needed windows service. constructed windows service project pretty following microsoft's recommendations , service runs , starts , stops fine doesn't start application converted console app service. i'm having trouble understanding why.

question: how start long running process using windows service? can windows services not utilize code in class library's?

}

normally if have objects should exist lifetime of service, not idea have them local variables in onstart method. go out of scope , garbage collected.

i.e., make timer member variable of class , see whether makes difference.
