"Read-Only Region" Visual Studio 2008 options

Extends

In Tools/Options/Environment/Fonts and Colors, If you choose to "Show settings for" Text Editor and look in the Display items dialog it says there' a "Read-On开发者_运维技巧ly" region you can set the font for.

I'm not sure what's that for? Where do you encounter the read-only regions this dialog wants to set the font for?

According to the help file:

Read-Only Region: Code that cannot be edited. For example code displayed in the Code Definition View window or code that cannot be modified during Edit and Continue.
