In 2016, Microsoft introduced a modern system called .Net Core. This is not inherently an updated and upgraded version of the existing .net system. Microsoft created this system as a completely unused system. In today's web world, everyone needs to create secure, flexible, adaptable, and cloud-ready web-based applications. So, if we are going to use ASP .NET CORE instead of ASP.NET MVC today at some point when using it recently, then we need to understand the benefits we get from it.

In Asp.Net Center you can get some focus on Asp.Net MVC. According to Microsoft, Asp.Net Center can be a compatible system for creating Web and cloud applications. It is basically a completely open-source stage. 

If you're thinking of building a PC program or a cross-platform computer program, you've probably heard of ASP.NET and ASP.NET Center. Both are defined from .NET, a Microsoft system that is suitable for C# and C++ but is also compatible with less common dialects such as F# and VB.NET. The system is available under open-source and Microsoft licenses. It was originally intended for PC development only, but in recent times it has also been connected to the operating system. The reason for using .NET is its simplicity. You'll quickly be able to dress up, use library components, and monitor surrounding layers. 

However, although .NET simplifies the development process, graphically representing some of the concepts behind the framework is a challenge for many developers. This is especially true to distinguish between ASP.NET and ASP.NET Core.  

PLATFORM INDEPENDENT

ASP.Net Core is a cross-platform framework. So using this framework we can develop any application for any operating system like Windows, Linux, macOS, etc. We can use this framework to develop web applications, console applications, or desktop applications that can be deployed in any operating system. In addition, this framework cloud environment for development and deployment. 

INSTALLING 

In the case of installing a related application developed in the .Net framework, it is always a package installation and also requires a runtime environment for Windows in the operating system. However since .Net Core is cross-platform, the applications developed in it need to be prepackaged and installed separately for the package. Developers must compile Nuget packages, including in .Net Core. 

.NET AND .NET CORE SUPPORT

Because .NET Core does not support all the options and features offered by the latest version of the .NET Framework. However, it will be used as a subset of the .NET Framework. In addition, .NET Core continues to be compatible with the .NET Framework through the traditional .NET library. Therefore, developers can still run applications developed with the .NET Framework after upgrading to .NET Core. 

LIBRARY COLLECTION

The .NET Framework and .NET Core allow developers to benefit from powerful catalog libraries. But .NET Core uses a redesigned common language runtime called CoreCLR and picks up a common type of library called CoreFX. As a result, developers have the flexibility to decide and fully utilize the libraries required by each application and improve application performance by eliminating redundant libraries. 

APP DEVELOPMENT

.NET Framework does not include any frameworks or sustainable tools for mobile application development. But .NET Core is compatible with Xamarin using the .NET Common Library. So developers can get the most out of Xamarin to write cross-platform mobile apps in C# with a shared codebase using the same APIs. They will use the tools provided by Xamarin to customize the mobile application for each mobile platform such as Android, iOS, and Windows Phone. 

MICROSERVICES

In the case of .Net Core, this framework makes the developer's job very simple in developing microservice-oriented systems, which is too complete in the case of the standard .Net Framework. Systems are inherently composed of many independent and dynamic microservices, so developers are forced to focus on individual microservices. .NET Core allows programmers to develop custom microservices by mishandling different programming languages, technologies, and frameworks. In addition, developers can build a robust system by seamlessly combining multiple microservices. 

PERFORMANCE AND QUANTIFIABILITY

.NET Core is more convenient than .NET Framework in improving the performance and quantification of the application. It allows developers to dramatically improve application performance without deploying hardware or infrastructure. Additionally, it allows developers to build, verify, and deploy applications directly to the cloud environment. As a result, developers can upgrade to .NET Core to improve the performance and quantification of their applications without wasting time and energy. 

SERVER AND CLIENT-SIDE DEPENDENCY

In the case of .Net Frameworks, we mean that developers know very well how to reference a DLL or Nuget package in a project or solution using the Visual Studio IDE. So, with the help of Visual Studio IDE, we can deploy our applications in operating systems including Windows, Linux, or Unit.

Its Server aspect manages dependencies. Client-side dependency management is important because the client side contains many completely different packages than the server side. The client side will definitely have jQuery, Bootstrap, Grunt, all JavaScript frameworks like AngularJS, Backbone, etc., images, and fashion files. Here, "Bower" and "NPM" are the names of the two most important open-source communities for maintaining client-side package management in a dependency framework. 

Some Common Misunderstanding

1. You already know what .NET is and understand its purpose. However, we still need to clarify the ASP part. The active service page is basically an HTML page that runs based on scripts and is used to build web applications.
2. Active service pages can be previewed from any browser, including the mobile version. ASP is commonly used for the backend of web applications. They are used to connect client-side and server-side dedicated input and output.
3. To make .NET more suitable for web application development, Microsoft chose to release the ASP.NET framework, a version of .NET specifically designed for the web backend.  

Benefits of Building Web Apps as an ASP.NET?

Microsoft has enabled ASP support to allow developers to use Microsoft tools, the Microsoft ecosystem, as well as C++ and C# for web and desktop development. As a result, they achieved their goal of providing a 100% cross-platform development environment. The main advantages of using. NET-based development tools as a web development tool are:  

1. The possibility to write backend with C#: the user interface, as usual, is written in JavaScript and its frameworks. For the backend, however, developers can choose from a number of technology groups, and Microsoft's goal is to facilitate the development of a C-based backend. Developers can use JET packages and work in Visual Studio.  
2. A single development environment for JS, HTML, CSS, and C# development: Developers can generate syntax for dynamic web applications and instantly preview the application output sent to the user. 
3. .NET framework allows seamless integration of C# with JavaScript and provides ready-to-use libraries, templates, and plugins to develop Progressive Web Apps and Single Page Apps. 

Another question here might be why are you using a C# #-based backend development framework. What are the specific benefits of .NET?

.NET does exactly what all good development frameworks are supposed to do. It provides developers with off-the-shelf application architecture, a library of templates and page templates, and built-in web application features (such as authentication, access control, page rendering, etc.)

In addition, developers work in code editors that automatically complete code snippets, highlight code, efficiently organize through different sections, and support real-time editing.  

ASP.NET Core vs ASP.NET RelatIon?

You already understand the difference between .NET and ASP.NET. Just to recap:

NET is a C#, C++, and F# framework that makes desktop development easier and faster.

ASP.NET is a framework that is functionally similar to .NET except that it is suitable for writing backends for websites and web applications.

Developers can use the same tools, libraries, and frameworks to create web and desktop projects. This way, the desktop development team can easily learn back-end development, development takes less time, and cross-platform development becomes easier. However, this is not the only difference in the .NET ecosystem. ASP.NET is just one version of the framework. Another is called ASP.NET Core.  

ASP.NET and ASP.NET Core the Same?

ASP.NET was the first version of the .NET framework suitable for the web. ASK.NET Core is an improved version with richer features, a more comfortable interface, new libraries, and other differences. We'll talk about their side-by-side comparison in a minute, but for now here are the main points:

1. ASP.NET Core is the continuation of ASP.NET, an improved version;
2. ASP.NET Core is available as an open-source engine;
3. ASP.NET Core is cross-platform and runs on macOS, Linux, and Windows, unlike ASP.NET which only runs on Windows;
4. Like ASP.NET, ASP.NET Core is based on the Model-View-Controller framework, like most web development frameworks;
5. ASP.NET Core has strong cloud support and better modular architecture support than ASP.NET.

So ASP.NET Core is a newer and more convenient version of ASP.NET. The Microsoft team understands what can be improved in terms of user experience and improved functionality.  

.NET Core and .NET Framework the Same?

Likewise, since ASP.NET has been split into a traditional .NET version and a newer Core version, the classic .NET framework has gone through a similar transition. That's why developers now see a need for two tools: .NET Core and .NET Framework.  

What is the difference between the two?

The .NET framework has been on the market for longer, which is why its ecosystem is much more complex. It's not just about patches, library updates, and tutorials: even in the job market, .NET framework skills are highly valued, even if it's technically not the version. Latest.

Scenarios for using .NET framework

So many teams prefer to work with .NET if they support tools that were developed before Core came out. Another common scenario is when a team familiar with .NET doesn't want to spend time learning basic functionality because they need to meet deadlines quickly.

The latest version of the .NET framework is 4.8. and there will be no more. Sooner or later you will have to switch to the Core version – no doubt about that. 

Scenarios for using .NET Core

If you're starting a new project and building the team from scratch, we strongly recommend upgrading to a newer base version. On the one hand, it's really improved. Developers moving from the .NET version to the Core version all agree that the interface has become much better. Although it takes a while to get used to this new feeling, the game is definitely worth it.

Furthermore, although .NET is still in high demand in the market, the situation is sure to change soon. Microsoft may completely discontinue support for all versions. It would certainly be better to develop in sync with official updates, i.e. using the Core version.

Issue with .NET Core: Although this version will surely dominate the market soon, it is not yet. Currently, the ecosystem is increasingly poor, there are not many educational resources, open source utilities, and recruiting an experienced .NET Core developer is a challenge.   

ASP.NET Core vs ASP.NET

So, across this comparison, we mentioned multiple times that Core is an updated version of the network, which is supposedly better. To see if that’s really the case, let’s zoom in on both frameworks’ technical characteristics. 

ASP.NET

1. A platform for developing desktop, web, and cross-platform applications. The first version of the platform was released in 2002 and was based on the .NET framework. The platform relies on the HTTP protocol for requests and communications.
2. ASP.NET has three main development modes.
3. Webforms: ASP.NET helps build event-driven applications, manage user input into forms, and enable real-time user interaction. 
4. VMC: ASP.NET is a model-driven view controller for connecting logic, data, and application interfaces. Developers can clearly separate the three application components and preview how the entire application will change after the model, view, or controller is updated.
5. Webpage: This platform allows developers to create dynamic HTML web pages. You can connect the backend code to the front-end function to test its performance and actual look and feel. 

ASP.NET Architecture:

1. ASP.NET is based on the .NET framework, which is why it shares most of its main components with. NET.
2. Support multiple languages: The main language for .NET development is C#, but it also supports F#, VB.NET, C++, and others;
3. Library: ASP.NET provides reusable code, interface, class, and value components for . NET-based web development.
4. Language runtime: Developers can detect code problems, handle exceptions, and profoundly modify the codebase. 

Advantages:

When ASP.NET first appeared, it impressed .NET developers with many useful benefits. However, they look a bit less promising these days as Core has inherited most of them. However, let's take a look at the main positive aspects of .NET, as they will also help us better understand Core's features. 

1. Security and access control: The codebase is protected with Microsoft authentication; developers can also configure safety settings early on during development;
2. Fewer lines of code, more functionality: ASP offers a convenient view of code lines, grouping the codebase and shortening the syntax;
3. Built-in HTML generator. ASP.NET supports HTML and allows previewing of web pages automatically;
4. Support of multiple languages: Although ASP.NET is mainly used with C#, it’s not an obligatory requirement; you can use any language, including Java or Ruby.
5. Realtime Windows server monitoring: The server checks the number of components, pages, and integrations;
6. Garbage collection and security alerts: The framework detects memory leaks, flawed loops, etc;
7. Built-in caching system;
8. Separation of the application's internal logic and content. 

Overall, ASP.NET offers many great features for editing, managing, and monitoring code. It connects the application backend with other components, giving developers a complete idea of ​​how their application will function and look. 

ASP.NET Core

Just like we looked at ASP.NET, let's look at Core's architecture, components, development style, and benefits.

ASP Core is a new version of ASP that is already available as open source and can be run not only on Windows but also on Linux and Mac. With this update, ASP.NET is becoming more and more accessible to teams that often work outside of the Microsoft ecosystem.  

Architecture

ASP.NET Core is a cloud platform where teams can build web and cross-platform apps from any operating system. This release is a combination of Model-View Controller and WEB API in a unified development system.

With ASP Core's MVC, users can perform model binding and validation according to their requirements, automatically setting parameters and converting values. In addition, the filtering framework automatically detects invalid patterns and blocks them for later sessions.

What used to be "References" in ASP.NET has become a Dependencies folder in ASP.NET Core. As soon as you start building the application, the platform exposes all dependencies by default and allows you to track their growth or decrease.  

Advantages of Using ASP.NET Core

1. Clear structure: The platform allows breaking applications into multiple layers, using clear architecture templates, and managing business logic, and UI files. 
2. Features are structured in Views and Controllers. Developers can organize functionality by feature folders, and create separate Areas with standalone sets of Views and Controllers.
3. Filters: In ASP.NET Core, developers can easily track middleware and duplication by assigning filters that would detect unwanted characteristics and clean up the codebase. You can filter models, exceptions, actions, resources, and authorization. Importantly, these filters can be structured in an organized hierarchy. 

ASP.NET Core has several other updates in terms of security, token-based authentication, client communication, and update control. More importantly, this extra functionality is very well structured in the app – clearly, the team has focused on reducing dependencies. You can isolate components and make changes automatically across the entire codebase.

Finally, ASP.NET Core can be hosted on Docker, and HTTP.sys, Apache, Kestrel, IIS, Nginx, and other systems. It is a great choice for cloud development and microservices, especially suitable for enterprise-grade projects.  

Conclusion

The best way is to use ASP.NET Core, as this is the new version that gives more opportunities to the team. Migrating to ASP Core from ASP.NET is a long-term investment: this way the team stays in sync with official Microsoft updates and can benefit from continuous improvements.

While there are use cases for ASP.NET it's generally not a good idea. You will slow down your business and cut off the team's official resources. Best not to wait for ASP.NET to become completely obsolete and possibly abandoned. Instead, take a positive approach and start the migration process.
