Question

I found some sample code posted at
https://groups.google.com/group/microsoft.public.dotnet.languages.csharp/browse_thread/thread/4d45e9ea5471cba4/4519371a77ed4a74?hl=en&pli=1
for self installing a Windows Service. I am in C# on fx 4.0. Trying
to figure out where I went off the rails…

My questions:

1. I created a Win Service project. In program.cs / main() I pretty much
   copied the code example. It appears most everything is working
   except launching a console window if I am in DEBUG mode (passing in –
   c of course). For some reason the console window never opens.
2. The other challenge I had was the call to StartUp() / ShutDown() in
   the console portion would not compile. I ended up have to initialize
   my service object and then call it.
3. I am getting the following error when the Console.ReadKey() method is called:

Cannot read keys when either
application does not have a console or
when console input has been redirected
from a file. Try Console.Read.

My code and stuff:

An image of my project structure:

NOTE: I was duplicating the startup sequence in the TestHarness when
in DEBUG mode. If/when I get this working I will be dropping that
from the solution. The Library project is where the majority of my
code lives.

Answer 1

And I found my answer! My project properties were set to Windows App instead of Console App. DOH! (Project Properties > Application Tab > Output type:)
