In this window, you’ll do most of your work, such as working with forms and editing code. In the illustration, the window shows a form in the Form Editor. At the top of the window, the Start Page tab and the Form1.cs [Design] tab appear. In Visual Basic, the tab name ends with .vb instead of .cs
Solution Explorer window:
In this window, you can view and navigate to all items in your solution. If you choose a file, the contents of the Properties window changes. If you open a code file (which ends in .cs in Visual C# and .vb in Visual Basic), the code file or a designer for the code file appears. A designer is a visual surface onto which you can add controls such as buttons and lists. For Visual Studio forms, the designer is called the Windows Forms Designer.
In this window, you can change the properties of items that you choose in the other windows. For example, if you choose Form1, you can change its title by setting the Text property, and you can change the background color by setting the Backcolor property.
