ASP.NET vNext is a lean and composable framework for building web and cloud applications. ASP.NET vNext is fully open source and available on GitHub. ASP.NET vNext is currently in preview, and in this talk Fowler and Edwards will put it all into Context. vNext apps can use a cloud-optimized subset of the .NET framework. This subset of the framework is about 11 megabytes in size compared to 200 megabytes for the full framework, and is composed of a collection of NuGet packages. What does that mean for compatibility? When would you choose vNext and when would you not? You don't have to use Visual Studio to develop ASP.NET vNext applications. You can develop and run vNext on platforms that Visual Studio doesn't run on. But Visual Studio provides the best development experience, and we'll cover ASP.NET vNext both inside and outside the IDE.
Mobile continues to expand and evolve at a rapid pace. Users expect great native experiences in the palm of their hands on each and every platform. A major hurdle for developers today is that each platform has its own programming language and tools to learn and maintain. Even if you tackle the burden of learning Objective-C and Java you will still have to manage multiple code bases, which can be a nightmare for any development team large or small. It doesn't have to be this way as you can create Android, iOS, Windows Phone, and Windows Store apps leveraging the .NET framework and everything you love about C#.
