.NET Core is an open-source framework that allows developers to build cross-platform applications that run on Windows, Linux, and macOS. It supports command-line programs, libraries, web APIs, and ASP.NET Core web applications. .NET Core enables the creation of mobile, web, cloud, game, AI, and IoT applications with greater flexibility. Popular cross-platform frameworks include React Native, Flutter, Cordova, and Ionic. ASP.NET Core is well-suited for building enterprise-grade cross-platform applications due to its cross-platform capabilities, flexible deployment, modularity, open source nature, and support for microservices architectures.

1. Built Cross-Platform Application with .NET Core
Development
A open-source framework that is free and freely available called.NET Core can be
utilized to develop cross-platform software that runs on Windows, Linux, and macOS. It
is able to run applications on hardware and in the cloud as well as over the Internet of
Things. It supports four scenarios of cross-platform usage of command-line programs
libraries, command line apps, Web APIs, and ASP.NET Core Web applications. The latest
.NET Core 3 version is compatible with forms that render windows, such as WinForms,
WPF and UWP.
Additionally, the creation of mobile applications, online applications, cloud-native
software games and Artificial Intelligence (AI) applications, as well as Internet of Things
(IoT) applications are now possible with greater flexibility due to .NET Core. Learn the
details about this new technology as well as how cross-platform apps are created with
it.
What is a Cross-Platform Application?
Mobile apps that are designed to function across multiple mobile platforms are called
cross-platform applications. They can be used well with iOS and Android in addition to
other platforms.
With cross-platform mobile application development, developers are able to create
apps that function on several platforms, using one code base. This means that
businesses can launch the app quicker and with better quality. The app can reach more
people since it runs on different platforms for mobile devices.
It is ideal for startups because of its rapid development speed, short turnaround time,
and cost-effective quality. Many of the issues encountered when developing mobile
apps can be addressed through the creation of cross-platform apps.
Benefits of Cross-Platform App Development
• It draws the attention of numerous entrepreneurs and SMEs since creating apps
can cut down on costs and time. As we previously noted, cross-platform mobile

2. app developers' hourly rates were much less than Native mobile developers. This
is still the case even today. Companies that use cross-platform mobile
development will have lower costs per unit. However, it also requires one team
of programmers instead of many as in native applications. In addition, because
only the one development cycle is needed making a product with an app
development framework that is cross-platform is quicker than developing one
that is native to the platform. Since this technology requires only just one cross-
platform application It has the advantage of being simpler to maintain since it
requires just one base of code.
• In the process of creating high-quality web-based applications, developers of the
most reputable .NET development companies often concentrate on the
performance. When it is about the.NET Core Framework, the high-performance
component is the most important element. Furthermore, this framework
optimizes code when it is being written and greatly increases its performance. It
is currently it is among the most efficient web-based application development
frameworks.
• Not to be left out, the cross-platform approach provides an expanded consumer
market for products that are tech-related. A mobile app that is able to be easily
used on all platforms opens up an even larger market. The more people interact
with your app the greater chance you have of securing paid users.
Top Cross-Platform App Development Frameworks / Platform-
agnostic app development frameworks
React Native
React Native is the go-to framework for developing cross-platform apps as per a Statista
study. In the years 2019 and 2020 42 percent of developers worldwide used it. In 2021,
the percentage fell to 38 percent. (Still, it was the most popular in the last 3 years).
JavaScript is supported when using React Native. Alongside Swift, Python, and Objective
Programmers can also create their own modules using CSS as well as JavaScript. The
source code of the cross-platform app framework is open-source and reusable. React
Native is an excellent alternative if you want to quickly build a prototype. It is because it
converts quickly sources code into native elements. When it is agile it is extremely
effective.

3. Flutter
In the research React Native as well as Flutter are two of the most well-known cross-
platform frameworks for apps. It was introduced in the year 2018, and it is an SDK
(software development kit) that is based on Dart Google's own language. It has a range
of UI elements and widgets. Its rendering engine is efficient. It's Hot Reload function
enables real-time visualization of changes to the code without having them saved.
Cordova
When it comes to the cross-platform developer options, Apache Cordova comes in the
third position. Furthermore, Adobe has made this framework open source. Alongside
HTML5, Cordova also makes use of CSS, JavaScript, and React Native. It allows the use of
many important phone features, including cameras, GPS, notifications, contacts, and
much more.
Ionic
It is the HTML5 SDK Ionic Framework (SDK) is free and, more important, it is free to use.
Because of its extensive collection of reusable UI elements including gestures,
typography themes as well as various other features, Ionic can be a great alternative for
developing interactive, enjoyable applications. It utilizes HTML5, CSS, and JavaScript
similar to Cordova. Ionic is a great choice to use for Progressive Web Apps since it makes
use of the Virtual DOM, TypeScript, async, and JSX APIs, which makes it easy to utilize
(PWA).
Why should you choose .NET Core to build Cross-Platform
Applications?
A brand new robust, feature-rich, and robust framework known as ASP.NET Core lets
programmers create web-based applications with rapid APIs. Let's look at the
components which make ASP.NET Core the best option to build enterprise-grade
applications.
1. Cross-Platform

4. Windows, Linux, and macOS all run on .NET Core. This allows users to use any platform
for application. The developers who provide ASP.NET App Development services have
the possibility of sharing code and their expertise within a comfortable environment.
You can make use of NET Core to develop everything from mobile applications running
across Android, iOS, and Windows to server-based applications for enterprise which
operate using Linux or Windows Server, or even gigantic microwaves operating in the
cloud.
2. Flexible deployment
It is possible to create up.NET Core machine-wide, user-wide or side-by side and
incorporate the technology into an application. It is able to serve as a host for ASP.NET
Core apps, enabling applications to use Linux-based Docker containers currently being
used in conjunction in conjunction with it.
It is possible to include .NET Core in your application as well as be installed in a machine-
wide, user-wide, or alongside. You can utilize it together with Docker containers that
typically run Linux currently and can also be used to host ASP.NET Core apps, enabling
users to benefit from the advantages offered by containers and microservices.
3. Modular
The .NET Core web application development framework allows using NuGet package.
It's currently possible to allow programmers to work with NuGet packages, not
assemblies. The.NET Framework usually relies on Windows updates to give framework
updates, whereas the.NET Core uses the package manager to provide updates.
4. Open Source
Since it's open-source, NET Core is licensed under its MIT as well as Apache 2 licenses. It
is a property of the independent nonprofit.NET Foundation, which supports the open-
source-friendly, innovative, and commercial.NET ecosystem. Through participating in
the.NET open-source codebase More than 25,000 programmer employed by over 1600
companies already provide asp.net support for development.
There's been an explosive increase in the .NET community and it is proud to have many
communities and libraries that are available at no cost. Apart from Microsoft and its
community and the community, there are other stakeholders involved in the .NET

5. platform's future development is guided through the Technical Steering Group members
such as Google, Red Hat, JetBrains, Unity, and Samsung.
5. Microservices architecture
Moving across a service boundary using the use of a variety of technology is possible
using microservices designs. When it comes to the creation of new microservices that
work with existing microservices or services, the technological mix is quickly
accepting.NET Core. For instance, it's possible to join microservices or microservices
created by using the.NET Framework. Ruby, Java, and other technologies.
Benefits of the use of .NET Core
Here are a few of the major positives of this framework over the ASP.NET Core
Framework over the ASP.NET framework:
high performance: the performance was considered in the development of the ASP.NET
Core framework. Its Kestrel standard web server was optimized to efficiency through
members of the ASP.NET team. It is believed that ASP.NET Core with Kestrel is the
fastest of over 400 frameworks according to Tech Empower who has conducted
benchmarks for different frameworks.
Cross-Platform: ASP.NET Core is based across the multi-platform .NET 5.0 platform. It's
not connected to a Windows operating system. You can create and test production-
ready ASP.NET Core apps on Linux or on a Mac. If you choose to run your application on
Linux it is not necessary to purchase Windows licenses, leading to substantial savings in
costs.
Simple to maintain: .NET Core is known for its simplicity and requires less programming
as compared to other frameworks. It lets developers create applications that require
less code that makes it easier to automate maintenance. In the end, developers must
cut down on the amount of statements that are that are used and also improve the
structure of coding.
Conclusion

6. The ability to run applications on different devices is just one of.NET Core's main
advantages. An application that is framework-dependent and is able to run on different
platforms can be created in a short time. Developers' lives have been significantly easier
due to the constant updates and additions and the business websites are now more
lucrative. In the end, ASP.NET Core has emerged as the best choice for businesses to
develop cross-platform web apps. To create cross-platform web applications for your
company consider an ASP.NET development firm that is capable of adapting to your
needs.
