Microsoft has released the Office 2013 Developer Tools for Visual Studio 2012, so developers can create, edit, test, debug, package, and deploy apps for Office and SharePoint.
"The Office Developer Tools for Visual Studio 2012 provide broad and deep support, ranging from new templates to new designers to a whole host of integrated lifecycle tools. They enable developers to create, edit, test, debug, package, and deploy apps for Office and SharePoint, across all current Office and SharePoint hosting models and app types. In addition, beyond supporting a new application model based on web technologies, these tools also provide full support both for VSTO Add-ins and SharePoint Solutions," Microsoft stated in an official blog post. Developers can also utilize a validation experience, that comes with the Developer Tools, and allows for easy fixing of common errors prior to the app being submitted to the Office Store. The Developer Tools also provides improved workflow designers and remote debugging. Hit the download link below to grab the tools.
