Error "Could not find xxxx.Program specified for main method" creating Windows Service from MS example

Question

I am following this Microsoft guide to create a windows service.

However when I try and build it on the auto generated page called "Program.cs" That has this code in it

namespace BetfairBOTV2Service { static class Program { /// <summary> /// The main entry point for the application. /// </summary> static void Main() { ServiceBase[] ServicesToRun; ServicesToRun = new ServiceBase[] { new BrainiacVersion2() // not green though!!!!! }; ServiceBase.Run(ServicesToRun); } } }

I get this error "Could not find BrainiacV2.Program" specified for Main Method

I did everything the tutorial told me to.

I have an App.Config, a Program.cs (code above), a BrainiacV2.cs which holds all my code for the service and starts like this

namespace BetfairBOTV2Service { public partial class BrainiacV2 : ServiceBase { public BrainiacV2() { InitializeComponent();

My ProjectInstaller.cs with two installer objects on them (name) serviceInstaller Display Name: My new BetfairBotV2 ServiceName: BrainiacVersion2

And that is that.

This is the only error I am getting

The solution is called BrainiacV2

I have tried changing the code in Program.cs to

new BrainiacV2()

which turns it green but then I just get

Could not find BrainiacV2.Program specified for main method.

What am I doing wrong or need to change?

Any help would be much appreciated - thanks!

Win 7, 64 bit, .NET 4.5, C#

After renaming project and default namespace. I also had to change this:

enter image description here

So in your case at the creation of the project, the default Main was located in BrainiacV2.Program, but you do want to run Main in BetfairBOTV2Service.Program

I had to change my namespaces and classes around. It was nothing to do with that error (not a very helpful one!)

namespace BrainiacV2 { static class Program { /// <summary> /// The main entry point for the application. /// </summary> static void Main() { ServiceBase[] ServicesToRun; ServicesToRun = new ServiceBase[] { new Brainiac() }; ServiceBase.Run(ServicesToRun); } } }

Once I had done that it all worked!

A namespace issue it seems.

Would be nice if the error message was a bit more helpful though, as a lot of guess work was involved!

Thanks for your help.

Looks like you're specifying the wrong class name. See the comments below.

namespace BetfairBOTV2Service { static class Program { /// <summary> /// The main entry point for the application. /// </summary> static void Main() { ServiceBase[] ServicesToRun; ServicesToRun = new ServiceBase[] { new BrainiacVersion2(); // <-- this is what you have new BrainiacV2(); // <-- this is what you need }; ServiceBase.Run(ServicesToRun); } } }

FWIW, I have a couple of tutorials - here and here - that show you how to create a service and have it install itself.

HTH

If u notice my comments in the first code snippet, I tried what u suggested and it goes green (the code) but I get the same error "could not find 'BrainiacV2.Program' specified for Main method

I ran into the same issue some minutes ago, and while searching the web for an explanation, I came across this post. You might have found an answer over the years, but I'd like to share my solution. The error arrived at my project when I changed the namespace of the Program class. By aligning the startup project to the new namespace, my project is working again.

So, in your case, the startup-project should become BetfairBOTV2Service.Program.

IN my case i renamed my solution and many other files and gave this error . got solved : in csProj file the start-up file still had the older name which was now changed , so after changing it , I was able to build successfully.

I had the same issue when creating a Deployment project in the same namespace as Project1. In addition to setting the namespace, removing outputType and StartupObject from my Deployment.csproj fixed it.
