Telerik UI for ASP.NET Core R3 2018 SP1 (v2018.3.1017) Retail

ASP.NET Core MVC is a complete rewrite of the .NET framework, delivering exciting changes and expanding the reach of .NET apps. Here’s some of what’s new:

.NET Core and Visual Studio Code enable you to develop and deploy apps on any OS—Windows, Linux or Mac
Tag Helpers provide easier views creation and UI definition
Nuget, Bower and Gulp package managers and automation tools boost your productivity
Unified MVC and Web API programming model simplifies development

As usual, we at Progress strive to deliver tools leveraging the latest technologies, so that your apps are always modern. This is why we were the first vendor to deliver official ASP.NET Core MVC support in their UI components. Read on to see how Telerik UI for ASP.NET MVC leverages ASP.NET Core MVC features to speed up your development.

ASP.NET Core is now live and developers around the globe are highly excited to give it a spin. Now that it’s released, more and more developers are about to start new or to migrate existing apps onto it. This means the need for beautiful and high quality UI components that run on the new Microsoft framework is increasingly vital.

What’s new in the Kendo UI MVC wrappers for ASP.NET Core?

Tag Helpers—we are following the ASP.NET Core specification and we have included Tag Helpers for some of the popular components: NumericTextBox, Button, Window, DatePicker and TimePicker. We plan to add more tag helpers in the next releases, but it will be awesome if you share feedback on exactly which components you’d like to define and configure through Tag Helpers.
New VS template—You can now use the new Telerik template to quickly setup and create a project for ASP.NET Core.
GitHub Demo app—The demo app is now obsolete and will be replaced by a brand new demo app for ASP.NET Core in the R3’16 release.

Cross-Platform Development and UI for ASP.NET MVC

Probably the most significant feature of ASP.NET Core MVC is the introduction of the new light and modular .NET Core runtime, which is OS-neutral. For the first time in .NET history, you can build applications and deploy them on Windows, Linux and Mac OSX devices. And on top of all that, it’s an open source solution so it’s free!

UI for ASP.NET MVC fully supports the .NET Core runtime, and helps you build beautiful responsive web experiences crossing the boundaries of the Windows world.

Visual Studio Code and UI for ASP.NET MVC
VS-Code

With ASP.NET Core MVC comes Visual Studio Code, a lightweight version of Visual Studio that can be used across platforms—Windows, Linux and Mac OSX. It blends a rich UI code editor with code assistance and navigation, along with integrated debugging experience.

UI for ASP.NET MVC integrates naturally with Visual Studio Code, making ASP.NET Core MVC app development a breeze on any platform.

Tag Helpers and UI for ASP.NET MVC

Tag Helpers are the new HTML-friendly way to create views and define UI in ASP.NET MVC applications. They are recommended as the better alternative to traditional MVC HTML helpers, while still allowing you to extend the elements with server MVC functionality. Tag Helpers are also much more “understandable” to front end developers and designers.

We are proud to announce that Telerik Tag Helpers are now available as part of our UI for ASP.NET MVC and include six of the most popular Kendo UI widgets: DatePicker, TimePicker, DataTimePicker, Button, Window and NumericTextBox.

Nuget, Bower and UI for ASP.NET MVC
Nuget and Bower

Popular package management and task automation solutions such as NuGet, Bower and Gulp are made first class citizens in ASP.NET Core MVC. That means every web developer can use Bower for client packages, NuGet for server packages and Grunt/Gulp for compilation, minification, etc., when building web apps.

UI for ASP.NET MVC takes advantage of these tools by providing a Bower feed for its client scripts, and a NuGet feed, hosted on our NuGet server, for its server wrappers implementation (see this help topic for details). Furthermore, you can build a custom script from the source using Grunt by following these steps.

Unified MVC and Web API Programming Model and UI for ASP.NET MVC

A prominent change in ASP.NET Core MVC is the unification and combination of MVC, Web API and Web Pages in a single programming model, which removes the overlap between the three separate frameworks. Moreover, the MVC and Web API controllers use the same Controller base class and routes.

The Telerik MVC product leverages this merge, which simplifies the development and streamlines the usage of MVC Web API architecture in .NET projects.
