VS 2005+Turn On Visual Studio 2005 Line Numbering
Many developer assistance tools, such as Microsoft's 'FxCop' refer to line numbers within source code. Though Visual Studio shows the current line number at all times, finding a referenced line is much easier when source code line numbering is enabled.
Visual Studio Configuration
The grid layout settings are controlled from the standard Visual Studio 2005 options menu. This is also available for the Visual Studio Express Editions such as Microsoft C# Express or Visual Basic Express. To view the options dialog box, select Tools, Options from the menus.
Show All Settings Mode
In some Visual Studio editions the standard options dialog box may be set to view a limited number of settings. If so, you will see only Environment, Text Editor and Debugging within the tree structure. To show all of the settings for Visual Studio, tick the Show all Settings checkbox at the bottom-left of the dialog. The advanced settings will appear.
Text Editor Settings
Once all of the settings are visible, expand the Text Editor branch of the tree. Here you can see a list of all of the languages for which settings may be modified. We will enable line numbering for C# code editing. Expand the C# node of the tree and select the General section to reveal the settings. To enable source code line numbering, tick the appropriate checkbox. Click OK to accept the setting and the line numbers will appear.
