Options, Text Editor, C#, Advanced

Use this dialog box to modify the settings for editor formatting, code refactoring, and XML documentation comments for Visual C#. To access this dialog box, click Options on the Tools menu, expand the Text Editor folder, expand C#, and then click Advanced.

Outlining

• Enter outlining mode when files open
  When selected, automatically outlines the code file, which creates collapsible blocks of code. The first time a file is opened, #regions blocks and inactive code blocks collapse.

Editor Help

• Underline errors in the editor
  Identifies build errors in code. When this option is selected, wavy underlines appear in colors that have specific meanings:

  • Parse errors are red.

  • Build errors are blue.

  • Build warnings are green.

  • Invalid Edit and Continue edits are purple.

  Move the pointer over the underlined code segment to see a ToolTip with information about the error.

• Show live semantic errors
  Identifies certain compile errors without explicit compilation, for example, declaring and using an unknown type or referencing an unknown property.

• Highlight references to symbol under cursor
  When the cursor is positioned inside a symbol, or when you click a symbol, all the instances of that symbol in the code file are highlighted.

Refactoring

• Verify results of refactoring
  Displays the Verification Results dialog box when you try to refactor code that contains build errors, or when refactoring would cause a code reference to bind to something different from its original binding.

• Warn on members with compiler generated references
  Displays a warning dialog when you try to refactor a member that has the same name as a compiler generated reference.

XML Documentation Comments

• Generate XML documentation comments for ///
  When selected, inserts the <summary> start and end tags automatically for XML documentation comments after you type the /// comment introduction. For more information about XML documentation, see XML Documentation Comments (C# Programming Guide).

Implement Interface

• Surround generated code with #region
  Inserts a #region <interface name> Member around the methods when Implement Interface or Implement Interface Explicitly is used.

Organize Usings

• Place 'System' directives first when sorting usings
  When selected, System using directives appear before other using directives. For more information, see Sort Usings.
