Visual Studio: JSON visualizer when debugging

Yes, use this addon on Codeplex.

archive.org - JSON Viewer on Codeplex

Actually it does work in visual studio 2010, but you have to unblock the assemblies. In explorer right click on the DLL and view properties the is a button to unblock the assembly.

Overtly visible disclamer: I wrote this and I'm giving it away for free via Microsofts Visual Studio Gallery. No ads, no link to my own site or anything.

I found this thread when looking for the exact same thing but seeing that http://jsonviewer.codeplex.com/ is "A visualizer for Visual Studio 2005" i felt that it was probably to outdated for my use. So I wrote a new visualizer instead (with built in jsonlint-support!). It has been tested with Visual Studio 2012 (but probably works fine for at least 2008 and 2010) and available from Microsofts Visual Studio Gallery.
