The Story of Synchronized Settings - The Visual Studio Blog - Site Home - MSDN Blogs.
This blog from the Visual Studio team provides an insight into how and why synchronized settings came about.
Barely a month has gone by since the announcement at Tech Ed North America 2013 yet Visual Studio 2013 Preview is available to download. TFS 2013 Preview is also available, however as I use the Team Foundation Services hosted by Microsoft, I’m just going to focus on VS 2013. .NET 4.5.1 preview is also available, which is installed when you install the VS 2013 preview. .NET 4.5.1 is also included in all installations of the Windows 8.1 preview. These products are classified as “go-live” by Microsoft, so they will support them in production.
