Now that you created your first Windows Store apps, check out the rest of the Dev Center. Here's an introduction to the different sections it contains.
Make your app stand out by learning how to design a great user interface. The topics in this section provide guidelines for app design, considerations for planning, case studies, graphical resources, and design templates.
Go to Designing UX for apps.
The tutorials in this Getting started section only covered some of the features of Windows Store apps. The Developing apps section provides detailed info and coding examples for the many of the other features available to your app (it's not an exhaustive list, though). There are three Developing apps sections for the different programming languages:
The Windows Store lets you reach the millions of customers who use Microsoft Windows. The Windows Store is a marketplace where you sell apps to customers practically anywhere in the world. Customers find apps relevant to their country or region in a consistent way across all devices. You choose to sell your apps in specific countries or regions, and you can specify a single price tier that prices your app in local currencies.
For more info, see Publish Windows Store apps.
Learn about core programming concepts, security, performance, and other advanced concepts. The topics in this section focus on providing background info on how things work.
Go to Concepts and architecture.
This section contains detailed info on the classes, properties, methods, events, styles, and other APIs that you can use to create Windows Store apps.
Go to API reference.
This section describes the programming languages available to you and any variations in the Windows 8 implementation of those languages. If you need help understanding and coding with the languages, this section will help you.
This section pulls together the features you need to build the kinds of Windows Store apps you want. It includes in-depth examples and white papers to help guide you along. These examples cross all the features you can read about in Developing Windows Store apps, but within the context of specific types of apps.
