Introduction to ASP.NET CorePrint
Microsoft has announced the next generation of ASP.NET at TechEd North America on 12 May 2014, which is called ASP.NET vNext. ASP.NET vNext includes new cloud optimized versions of MVC6, Web API3, Web Pages4, SignalR3 and Entity Framework7.
Features of ASP.NET vNext
ASP.NET vNext includes new cloud-optimized versions of MVC, Web API, Web Pages, SignalR, and Entity Framework.
MVC, Web API and Web Pages have been merged into one framework, called MVC 6. This will follow common programming approach between all these three i.e. a single programming model for Web sites and services.
For example, there is unified controller, routing concepts, action selection, filters, model binding, and so on. In this way, You will have a single controller that returns both MVC views and formatted Web API responses, on the same HTTP verb.
MVC 6 has no dependency on System.Web since it was quite expensive. A typical HttpContext object graph can consume 30K of memory per request and working with small JSON-style requests this is very costly. With MVC 6 it is reduced to roughly 2K. The result is a leaner framework, with faster startup time and lower memory consumption.
ASP.NET vNext has new project extension
project.jsonto list all the dependencies for the application and a
startupclass in place of Global.asax.
ASP.NET vNext apps are cloud ready by design. Services such as session state and caching will adjust their behavior depending on hosting environment either it is cloud or a traditional hosting environment. It uses dependency injection behind the scenes to provide your app with the correct implementation for these services for cloud or a traditional hosting environment. In this way, it will easy to move your app from on-premises to the cloud, since you need not to change your code.
.NET next version, .NET vNext is host agnostic. Hence you can host your ASP.NET vNEXT app in IIS, or self-host in a custom process.
.NET vNext support true side-by-side deployment. If your app is using cloud-optimized subset of .NET vNext, you can deploy all of your dependencies including the .NET vNext (cloud optimized) by uploading bin to hosting environment. In this way you can update your app without affecting other applications on the same server.
Dependency injection is built into the framework. Now, you can use your preferred IoC container to register dependencies.
.NET vNext use the Roslyn compiler to compile code dynamically. Hence you will be able to edit a code file and can see the changes by refreshing the browser; without stopping or rebuilding the project.
.NET vNext is open source and cross platform. It can run on Mono, on Mac and Linux.

I hope you will enjoy the ASP.NET vNext. I would like to have feedback from my blog readers. Your valuable feedback, question, or comments about this article are always welcome.
