How i change console application project to windows form app. project

I made a console application project for my project but its console application so how I change it to Form application... can anyone help me to change this console application to Windows form application.

Who know change console application codes to form application codes.

Please help me.. i want put "static void Main(string[] args) "codes in a button..

Create a new project using the Visual Studio "New Project' dialogue and select:

C# Windows Form App (.NET Framework)

Go to the designer and add a button, which can be found in the toolbox.

Then add a button click event handler, put your code inside the button click event handler.
