If you’re thinking about writing, or are currently writing a Windows 8 Metro style app, be sure to look at the Windows 8 app certification requirements for Release Preview. http://msdn.microsoft.com/en-us/library/windows/apps/jj128432.aspx
Having a great idea is just the start. Turning it into a compelling, attention-grabbing app that brings users back time and again, takes a lot of work.
There are only 7 main categories of requirements, but the devil is in the details. And there are a lot of details.
During the past few weeks I’ve had the chance to work with some brilliant co-workers on a reference app that we also hope will eventually make it to the Store. The team has devoted a lot of time to the look & feel of the app, trying to make sure it looks and behaves the way the user would expect it to. More to come on the development experience in future posts. . .
