ASP.NET 5 Open Source Web Framework
By Pujit Kaul
In February 2015, Microsoft announced a completely revamped version of ASP.NET. As an
open source web framework, ASP.NET 5 makes it easier for developers to create modern web
applications at reduced cost. The developers can now run ASP.NET applications on three distinct
platforms, i.e., Windows, Linux and Mac.
However, the latest version of the web framework does not support Web Forms and VB.NET.
It requires you to use C# while developing web application using ASP.NET 5. The version 5 of
the popular web framework also comes with several new features that will help you to build
perceptive dynamic pages rapidly.
Various New Features to Effectuate Modern Web Application Development
Option to Use 3 Runtime Engines
In the new framework, you have option to choose from three distinct runtime engines,
i.e., Full.Net CLR, Core CLR and Cross-Platform CLR. Full.Net CLR can be used as the default
runtime engine; whereas Core CLS is designed as a modular and cloud optimize runtime. On the
other hand, Cross-Platform CLR will enable you to create ASP.NET applications for Mac OS X
and Linux, in addition to Window. Thus, you can now choose the runtime according to the nature
and requirements of the individual applications.
A Unified Core Framework
The latest version of the web framework also comes with a unified core framework called
MVC 6. You can use MVC 6 to avail features of Web Pages, MVC and Web API. The unified framework
allows you to handle requests using only one type of controller for ASP.Net Web Pages, ASP.Net
MVC and ASP.Net Web API applications. So you are no longer required to write separate code
for each of these technologies.
Tag Helpers
The new version allows you to create Views using Tag Helpers instead of conventional
MVC helpers. The new option enables you to use HTML helpers in your Views. You can further
use the markup simply by extending the semantics of tags. The Tag Helpers will make your Views
appear more natural and readable. At the same time, you can take advantage of the HTML editor
to customize the output of HTML Helpers by adding extra markup.
Cloud Ready Configuration
The revamped framework further makes it easier for you to publish or deploy projects
in the cloud without worrying about different configurations. It comes with a cloud ready configuration
that simplifies the process of migrating or deploying projects in the cloud. You can further
help in the project migration or publication by converting the project into an Azure cloud
project. The converted Azure cloud project can be published in a quicker and easier way.
Option to Choose from Several Hosting Platforms
You also have option to host the web application on a number of platforms. The web framework
comes with a new modular HTTP request pipeline that supports Internet Information Services,
Kestrel server and Open Web Interface for .Net (OWIN) based server, while allowing users to
self-host the application through a custom process. As your application will not interact with
the web server directly, you can seamlessly switch from one hosting platform to another.
Built-in Dependency Injection
Your applications will now have access to a common dependency injection service. Likewise,
the common dependency injection service is also available to various frameworks like Web API,
MVC, Identity and SignalR. You can take advantage of the dependency injection service to effectuate
and simplify testing and composition. However, you also have option to replace the minimalistic
Inversion of Control container included in ASP.NET 5 with a container of your choice.
