VISUAL STUDIO EXPRESS PRODUCTS
Visual Studio Express products are a free set of tools for building applications for the cloud, desktop, phone and the web.
Visual Studio is a complete development environment from Microsoft for creating web applications, client (Windows) applications, and Windows Phone 7 applications. In contrast, Visual Studio Express is a set of free, entry-level products that features streamlined interfaces and core capabilities that focus on providing the tools that you need for creating applications for a single platform. For example, Visual Studio Express for Windows Phone provides the tools that you need to create games and applications for Windows Phone 7. Integration with Visual Studio Team Foundation Server, and advanced design, development and test capabilities, such as 64-bit development, unit testing and remote debugging, are not included in the Express products.
