There it is! GXView 1.0 beta is released!
GXView is a simple tool designed to make life easier for game developers. Particularly if you work with XNA, this tool is made for you. There will be more later, but the current version already contains many cool features. (xml editor, xnb reader/compiler, 3d viewer, texture resizer, screen capture…)
By the way, it’s still a beta version, so any feedback will be appreciated!
