You'll need to share you code to enable someone to provide assistance.

You can share everything at once if you make a snapshot of your workspace and provide the link to it.

You'll need to go into the properties for the project (right click on the project name in the Solution Explorer and click properties). In the application tab, there's an option for output type. Change this from Class Library to Console Application.

You can also start out with your project as a console application by using the Console Application project template when you create a new project.
