Microsoft is updating the recently launched beta of Windows Phone App Studio to improve performance and scalability after the new app development tool crossed 55,000 active projects. The service was launched in a bid by Microsoft in order to increase the number of applications that are available on Windows Phone by allowing all users to create their own apps without writing any code. The service allows users to choose from a number of templates to get started. Then they are able to add content such as images, videos, RSS, and Twitter feeds. Although it is being worked on, the company didn’t provide any details on when Windows Phone App Studio would become generally available.
