MSBuild Special Characters
This article applies to Visual Studio 2015. If you're looking for Visual Studio 2017 documentation, use the version selector at the top left. We recommend upgrading to Visual Studio 2017. Download it here.
MSBuild reserves some characters for special use in specific contexts. You only have to escape such characters if you want to use them literally in the context in which they are reserved. For example, an asterisk has special meaning only in the
Exclude attributes of an item definition, and in calls to
CreateItem. If you want an asterisk to appear as an asterisk in one of those contexts, you must escape it. In every other context, just type the asterisk where you want it to appear.
To escape a special character, use the syntax %xx, where xx represents the ASCII hexadecimal value of the character. For more information, see How to: Escape Special Characters in MSBuild.
