ASP. NET Core 3.0

ASP. NET Core 3.0: Build Modern Web and Cloud Applications (Top 13 Features + Types of apps can be Built Using .Net Core)

Hardik Patel
Hardik N Patel Technical Lead
Last Updated on May 27, 2026 | Written By: Hardik N Patel

Microsoft ASP.NET Core 2.0 is an open-source web development framework that allows .net developers to build cloud-enabled and internet-connected modern solutions. ASP.Net Core is a unified and cross-platform version of ASP.Net.

With the help of skilled and certified .Net developers, you can build ASP.NET MVC web applications, IoT apps, and mobile backends on Linux, macOS, and Windows; you can deploy it to the on-premises or cloud and run it on .Net framework or .Net Core.

At Bacancy Technology, we are a team of certified Microsoft experts helping businesses of all shapes and sizes to expand their business with full-cycle dot Net development services.

Leverage our ASP.NET core development services to build highly secure and robust solutions using the latest Microsoft technologies like .NET MVC, .NET Core, and SignalR to integrate it with client-side frameworks like Angular, React, Vue, Ember, KnockoutJS, and more.

.NET Framework Vs .NET Core: A Complete Comparison

Top 13 Asp .Net Core features

#1 Multiple Environments Support

Asp.Net Core offers support for controlling the application behavior across multiple environments. It is so convenient for developers to use environment variables while dealing with multiple environments. Upon your convenience, the developer can help you set up the variable at any value such as production, staging, and development as these are the framework provided values. The environment is represented by variable in the running application so it can be configured appropriately.

#2 Unified MVC and Web API Frameworks

Before ASP.Net core was introduced, developers were making use of MVC and Web API frameworks. MVP was used to build web applications similar to HTML. In contrast, Web API was used to create RESTful services using XML and JSON; however, with the help of ASP. Net Core, Web API and MVC were merged, and combining them has simplified software development.

#3 Enhanced Performance

Asp. Net Core is far better in terms of performance than the classic ASP.net. Microsoft has ensured about the superior performance with the latest technologies used in Microservices like Go, Node.js, and Java servlet. Networking, compression, and concurrency help to perform faster with .Net Core. The best thing is to decrease the size of HTTP request 2kb in ASP. NET Core that was earlier 30 kb in ASP .NET. Now the ASP.Net Core application is capable of handling 1.15 M requests, which is 2300% more than the ASP .Net 4.6.

#4 Integrated Dependency Injection

Dependency injection has always been the core part of software development, be it Angular or ASP .Net Core as it allows better code testability and weak coupling. The flexibility and modularity combine the whole new architecture to the dependency injection that is now a core part of ASP. NET Core. Now onwards ASP .NET implements the injection of the dependencies natively, software developers won’t be required any 3rd party tools to achieve this practice.

#5 CSRF – Cross-Site Request Forgery Protection

ASP .Net is a flexible and highly secure framework that generates anti-forgery tokens to restrict the CSRF attacks. It is one of those security features that helps to prevent such types of attacks like fund transfers, changed passwords, damaged client relationships, unauthorized fund transfers, and many more. CSRF validates user authenticated session and restricts the actions that users have not performed.

#6 Response Caching

Response caching service is a middleware service in ASP. Net Core as it stores and serves the responses from the cache. It eliminated the number of requests and reduced the amount of work that a web server is required to perform.

#7 Extensible Output Caching

Asp.Net Core supports output caching for the most commonly used resources and static files. So whenever a user opens an application, the user will be served by the cache so he can experience improved user experience of a web application. It is advisable to use Redis or similar providers to handle output caching.

# 8 Globalization and Localization

ASP.NET makes it convenient to localize numbers, text, and the date within your web application into different languages and cultures via resource files. It supports both localization and globalization, such resource files are considered as a central repository.

Globalization and localization allow a web application to support multiple cultures and preferences. Localization transforms the UI of the application into a specific culture, and ASP.Net Core customizes the app for multiple languages.

#9 Self Hosted” Web Applications

Sometimes you are required to have a web app that can be deployed to a desktop, not an IIS server. Prefix – ASP .Net profilers are the best example to take into consideration. With the help of the Kestrel web server, Asp .Net Core allows you to create a self-hosted web application in different ways. IIS sits as a reverse proxy that means you can deploy your app for non-server based use cases, like Prefix.

#10 Razor Pages

Another best feature of Asp .Net core 3.0 is the appearance of Razor pages. It is enabled in the startup class through dependency injection to make the development of scenarios more fluid. It allows the implementation of independent views of controllers while clarifying the architecture of the solution.

#11 Vast Ecosystem

You will be required to purchase this feature from .Net ecosystem from the NuGet package manager, partner network, and Visual Studio Marketplace. You can opt for this feature from the 50,000+ Asp.Net Core related NuGet packages, with the help of MVPs. Broad support network and the community it is so convenient to resolve technical queries.

#12 SPA Template

Asp.Net Core comes with inbuilt Angular and React to SPA Templates. When you are building a project using the SPA template, all the relevant packages of Angular and Reacted are automatically installed using NPM. It also supports Angular CLI to make the life of developers easier.

#13 Action Filters

This is one of the best features of extensible filters. It allows you to implement the functionality that can be applied to the controller without altering the actions. Filers are widely used to specify authorization, caching, error handling, and custom logic that you would like to implement in your application.

What Types of Application can be Built Using Asp .Net Core

The advanced framework of Asp .Net Core provides excellent flexibility to leverage the extra benefits of cross-platform nature, performance, and modern deployment options. It allows programmers to build their choice of the application, be it Web, Desktop, Mobile, Cloud, Gaming, IoT, etc. The apps built with .NET Core are supported on Windows, Linux, and macOS.
