Brace Completer is an extension for Visual Studio 2010 that automatically inserts a closing brace on the next line when you type an opening brace and hit enter. It works in C#, C/C++, CSS, and JScript files, and can be activated/deactivated on a per-language basis. Brace completion can also be activated on any other Visual Studio content type, but the indentation of the braces may not be correct.

Brace Completer is in the Visual Studio Gallery at http://visualstudiogallery.msdn.microsoft.com/en-us/0e33cb22-d4ac-4f5a-902f-aff5177cc94d
