To create a C# application in 60 seconds
On the File menu, click New Project.
Ensure the Windows Application template is selected, and in the Name field, type "MyProject". Click OK to create the project.
You will see a Windows Form in the Windows Forms Designer. This is the user interface of your application.
Open the View menu, and click Toolbox to make the list of controls visible.
Click Label, and then drag the label control to the middle of your form.
From the Toolbox, drag a button onto the form, near the label.
Double-click your button to open the Code Editor. Visual C# Express Edition has inserted a method called button1_Click that is executed when the button is clicked.
Change the method so it reads
private void button1_Click(object sender, EventArgs e) { label1.Text = "Hello, World!"; }Press F5 to compile and run your application.
When you click the button, a text message is displayed. Congratulations! You've just written your first C# application. Of course, this program is not very useful, but it does demonstrate the basic steps that you'll take in writing any C# application.
