To compile a program with Visual C# 2010 Express, follow these instructions:

1. Open Visual C# 2010 Express.

2. Click on New Project in the File menu.

3. Choose Windows Forms Application if that option isn't already chosen, change the name if you like and click on OK.

4. Point at Toolbox in the left margin and click on the Auto Hide icon at the top of the window (to keep the window to stay open and easier to work with).

5. Drag a Button to Form 1.

6. Drag a Rich Textbox to Form 1. Resize the textbox if you like.

7. Double-click on the button. The file Form1.cs will open with the caret ready to write code that will run when button 1 is clicked.

8. Write or paste this code where the caret is:

richTextBox1.Text = "Hello world!";

9. Click on F6 or on Build Solution in the Build menu.

10. Find the project folder (I very quickly changed the path to D:\Visual C# 2010 Express\; I don't recall right now what the default location was).

11. Find the file called, for example, WindowsFormsApplication1 of the type Program (.exe). in the bin\Release folder and copy it to the desktop or some other location. In my case, the path is D:\Visual C# 2010 Express\WindowsFormsApplication1\WindowsFormsApplication1\bin\Release\WindowsFormsApplication1.exe.

12. Click on the icon to start the program.
