1. All The Amazing Features of ASP.NET Core
To be a crackerjack, one should be acquainted with new technologies that are responsible
for a booming market full of innovative products and today’s exciting experiences.
Embracing technology is not easy due to the plethora of new updates, new apps, and
other new big crazes. But for professionals of a particular field, adopting an update is not
a big deal. They only have to get their hands dirty on all the new features and
upgradations as the basics remain the same. Today’s pick is a framework that enjoys the
title of best web development framework- Microsoft’s new version of ASP.NET Core. It is
a powerful cross-platform, open-source framework introducing very forward-looking
ways to create great-looking Web properties. It enables web developers to deploy highly
scalable web applications with the addition of every update, new and extended features.
Let’s discuss all its features in detail.

2. Top Asp.net Core features
ASP.Net Core 3.0 is an open-source, modular, community-focused framework to build
superior quality applications. It consists of many new features as well as some
fundamental changes to existing features. Let’s start with its main features.
Cross-platform
Asp.net Core applications can now run on any platform like Mac OS, Linux/Unix systems
and no more restricted to Windows only. Earlier, Asp.net apps were not able to run on
Linux and Mac, but now there is no need to create different apps for different platforms
using different frameworks. It facilitates the developers to select an operating system
for app development. With the cross-platform nature of ASP.Net, their applications can
be made available to more and more users across different platforms.
Container Support
Containers in cloud computing is a logical packaging mechanism used to include code
and all related dependencies in an image such that an application can be tested and run
quickly as well as effectively in different computing environments(hosts). Containers offer
virtualization at the operating system level. Asp.Net Core development provides support

3. to utilize these modern container technologies such as Docker- containerization platform,
Kubernetes- container orchestration system, etc.
High Performance
Performance is one of the key concerns of developers while building robust web
applications. ASP.Net Core libraries, tools optimization, faster release cycles, new concepts
related to space & memory allocation aid developers to write efficient & maintainable
codes with high performance. Giving a high priority to high performance and introduction
of the Kestrel web server made the ASP.Net Core as one of the fastest web frameworks
available in the market for IoT, mobile applications & clouds today.
Unified MVC & Web API frameworks
ASP.Net Core has combined the MVC and Web API frameworks instead of separate
structures. It gives a better and simplified development now as there was a lot of
confusion with the two frameworks.
Razor pages are also included in ASP.Net features that encapsulate the model and
controller code. It makes coding more productive where each page is self-contained with
its view and code organized together. It allows two-way data binding with which the
development of scenarios gets more fluid with isolated concerns.
Multiple Environments Support
ASP.Net Core brings improved support for controlling application behavior across
multiple environments. The developers can deal with multiple environments easily using
an environment variable. This variable can be set to any value such as Development,
Staging, and Production (default) which are framework provided values. The variable
represents the environment in which the application is running so that it can be
configured appropriately.
Dependency Injection
Dependency Injection is one of the most important features of ASP.Net Core. It gives a
loosely coupled code that is necessary to achieve extensibility, testability, and
maintainability. Dependency injection is used by all the framework dependencies like
routing, loggers, configuration, etc.

4. Web Sockets & SignalR
ASP.Net Core supports Web Sockets which provide full-duplex communication channels
over a TCP connection. It can be used in any web application that needs real-time
functionality like chat, stock tickers, games, etc. It also includes a full-fledged open-source
library, SignalR that simplifies adding real-time web functionality to apps.
SignalR allows server code to send asynchronous notifications to clients quickly. It is good
for apps that require notifications or high-frequency updates from the server,
collaborative apps, dashboards & monitoring apps, etc.
Cross-Site Request Forgery (CSRF) Protection
ASP.Net has a powerful and highly secured framework that generates anti-forgery tokens
to prevent CSRF attacks. Cross-site request forgery (XSRF or CSRF) refers to an attack
vector that tricks a web browser into an unwanted action on a web application when the
user is logged in. This can result in unauthorized fund transfers, changed passwords, data
theft, damaged client relationships, and more. So, the dot net core 3 framework validates

5. all the incoming XSRF tokens. An operation gets executed only if the validation is
successful.
Self-hosted Web Applications
ASP.NET Core applications can run as standalone Console applications without IIS hosting.
These can be self-hosted or hosted on Nginx for Linux distributions. One can easily deploy
an app with kestrel for non-server based use cases where IIS serves as a front end proxy
only.
Action Filters
ASP.NET Core offers many filters that make actions cleaner and maintainable by extracting
reusable code. Many built-in filters are available for authorization, resource caching &
performance, exception handling, action method execution, and more. Custom filters can
also be created.
Response Caching
In ASP.Net Core, response caching comes as a middleware service to store and serve the
responses from a cache. It reduces the number of requests to the web server as well as
the amount of work the web server performs to respond. It adds cache-related headers
to HTTP responses where the primary one is Cache-Control.

6. Globalization and Localization
ASP.Net Core facilitates the internationalization features to cater to the critical aspect of
web apps for localizing into different languages and cultures. It involves both
globalization and localization. Globalization allows us to have a web application that
supports multiple cultures and culture preferences. It displays the data in the selected
language.
Localization is the process of adapting a globalized application by translating the UI of
the application for the specific culture. ASP.Net core development customizes an
application for multiple languages via resource files. There are local resources, specific to
a page and global resources, common for the whole website.
Swagger/OpenAPI
Swagger or OpenAPI is a framework to design and document Restful APIs easily. It helps
the developers to test and manage the application while designing an API. .NET Swagger
implementations give numerous benefits like interactive documentation, client SDK
generation, API discoverability.
Other features
Along with all the aforementioned features, ASP.Net Core development has numerous
other features as follows:
 This open-source software gives great flexibility to add libraries and other framework
components according to the project needs.

7.  It has an active open source community for developers where dot net persons can share
code, discuss, deploy Core app to Azure, etc.
 Developers need to write a minimal amount of code as ASP.NET Core implements many
common APIs implemented by both .NET Core and .NET Framework.
 It has a cloud-ready environment-based configuration system.
 Asp.Net Core has a client-side package manager for JavaScript, jQuery, etc.
 It gives faster development by utilizing asynchronous programming patterns.
 The compilation in ASP.Net is easy as takes place within memory.
In Essence
ASP.NET Core is a high-performance open-source framework to take full advantage of
development tools on Windows, macOS, and Linux. It gives extensive opportunities to
create modern cloud applications & services, IoT applications, mobile back-ends, etc.
ASP.NET Core is an excellent choice for developing web applications but it is
