Microsoft provides extensive help documentation via the Help menu, which is an excellent way to get information quickly about Visual Studio, Visual C# and more. Visual Studio provides context-sensitive help pertaining to the “current content” (that is, the items around the location of the mouse cursor). To use context-sensitive help, click an item, then press the F1 key. The help documentation is displayed in a web browser window. To return to the IDE, either close the browser window or select the IDE’s icon in your Windows task bar.
