How to Choose a .NET Runtime for Your Application: .NET Core vs .NET Framework

Does .NET Core hold the key to the future? For quite some time, we’ve been debating whether it’s feasible. Thus, we have seen this technology is in demand for skilled developers. But, what are the differences between it and the .NET Framework, and how does using them effectively differ? Thus, as we explain in this post .NET Core vs .NET Framework, we’ll suggest ways to use each to their best advantage.

In the past, the .NET Framework was only compatible with Windows devices. Therefore, mobile devices, macOS and Linux can run .NET using the Xamarin and Mono projects. As a result of .NET Core, a standard base library is now available on Windows, Linux, macOS, and mobile platforms (via Xamarin).

There are four major components of .NET architecture:

• Implement .NET objects using the Common Language Specification (CLS). .NET application. Common Type System (CTS) describes all types in a common way and is a subset of CLS.
• In addition to classes, interfaces, and value types, the framework class library (FCL) collects reusable tools.
• Use Runtimes (also known as virtual machines or virtual machines) for execution of framework and .NET applications.
• Visual Studio is a popular tool for developing standalone applications, interactive websites, web applications, and web service APIs.

.NET Core vs .NET Framework

For the purposes of developing .NET applications, Microsoft maintains both .NET Framework and the .NET Core runtime. Both share a common API known as .NET Standard. So, this image highlights the main points of .NET Core vs .NET Framework.

Using .NET framework, develop Windows desktop and server applications. ASP.NET web apps are also among these types of applications. Server applications for Windows, Linux, and Mac, on the other hand, mostly make use of .NET Core. As of right now, you can’t design desktop applications with a user interface for .NET Core.   

It is object-oriented, C# is similar to other C programming languages. C# is therefore not hard for any developer proficient in C and versed in its complexities.  

In contrast, F# provides full cross-platform support. Therefore, developers with prior experience working with C languages may find F# easier to adopt. 

Besides Visual Basic, .NET Framework 2.0 and .NET Core 2.0 have limited support for Visual Basic.

The following table may help you make your decision .NET Core vs .NET Framework

Key Advantages of the .NET Framework

Let’s discuss .NET Framework’s benefits now. A .NET developer is in a rush to complete an app quickly, but doesn’t have much time. Then, you should choose the .NET Framework. The learning curve for .NET Core is ascending, however. 

The .NET Framework is an excellent tool for maintaining and upgrading .NET applications. However, porting an existing .NET application to .NET Core requires a number of tasks. The .NET Core framework offers fewer job opportunities for developers than the .NET Framework. 

.NET Core Advantages

.NET Core offers a variety of benefits to developers and projects despite its higher learning curve. However, .NET Core is the most effective technology option for building a new application. This new version of .NET Core from Microsoft is a significant update to the earlier .NET Core version. .NET Core is a great choice if you want a technology for future.

.NET 3.0 provides support for WPF and Windows Forms. Therefore, you can develop UWP, WPF, and Windows Forms apps with .NET Core 3.0 thanks to its extensive cross-development capabilities. With this, Windows Forms and WPF become more flexible and easier to integrate modern interfaces such as UWP.

When it comes to cross-platform development, .NET Core is a much better choice. One great thing about .NET Core apps is that they can run on multiple operating systems including Windows, Linux, and macOS. Visual Studio (VS) code, Microsoft’s open source code editing program, is also available to developers for .NET Core projects, and it’s compatible with all major platforms, such as Windows, Linux and Mac. The latest editing tools such as IntelliSense and debugging make VS Code a favorite of developers and code editors. In addition, many third-party code editors support .NET Core, including Sublime, Emacs, and VI.

The development platform for highly sophisticated, future-proof applications is .NET Core, but there are other reasons as well. 

In addition to supporting Microservices architecture, .NET Core provides cross-platform services derived from the .NET Framework, Java, Ruby, and other languages. 

Finally, .NET Core’s lightweight architecture, modularity, and unmatchable flexibility make it a popular choice amongst modern developers. The .NET Core apps are very easy to deploy in containers because of these qualities. 

Developers Should Use .NET Core :-

It is an open-source and cross-platform framework. As a result, it can be used to build applications across a wide range of platforms. Therefore, a large enterprise application or cloud application is usually refactored into microservices with this technology. In .NET Core vs .NET Framework, you should be clear to know where .NET core should be used and where it should not be used.

Use .NET Core When:-

• It supports several platforms:-When your application must run on more than one platform, such as Windows, Linux, and Mac, use it. As development workstations, it supports the following operating systems (and the list is growing rapidly):
  • Visual Studio is available for Windows as well as a new limited version for Mac.
  • Visual Studio Code supports Windows, Linux, and macOS .
  • On all supported platforms, you can use the command line.
• A microservice architecture is used. An example of a microservice, which is a service-oriented architecture, is a software application made up of small, modular business services. There is no restriction on which types of services can be created, deployed, or run. Microservices can be run on .NET Core, because it is lightweight and can be minimized. Adding microservices to it makes it scalable.
• A Docker container is used when using Docker. Microservices architecture and containers often go hand in hand. The lightweight and modular nature of .NET Core makes it an excellent container platform. The deployment of server apps to Docker containers is cross-platform. Containers can be used with the .NET Framework, but images are larger.
• Performance and scalability are essential for your system. A .NET Core application is recommended if maximum performance and scalability are sought. The importance of this increases when several hundred microservices are being used. It is recommended to use fewer virtual machines and servers. In addition to cost savings, improved efficiency, scalability, and user experience could result.
• When you run multiple versions of .NET simultaneously. To install .NET applications requiring different framework versions, developers should use .NET Core.  
• You can use the command line interface (CLI). The command line control and lightweight editors are preferred by some developers. There is a CLI available for all platforms supported by .NET Core. On production machines, it requires minimal installation. Furthermore, there is still the option of switching to an IDE like Visual Studio IDE.

When Not to Use .NET Core

In addition, it does not support all extensions and libraries or some .NET features. Eventually, it should be sufficient for most use cases although it may not be the best option for a few situations (currently). Here are some scenarios to consider:

• WPF and Windows Forms applications are not supported. For macOS, .NET desktop applications must be built with mono.
• There is no ASP.NET WebForm. They will not be ported to ASP.NET Core by Microsoft either.
• WCF services must be created. The .NET Core framework does not currently support WCF. ASP.NET Core MVC, however, would be better suited for developing a REST API.
• There is no support for third-party libraries. With .NET Core 2.0, you can link the .NET Framework and .NET Core. Even if you use a supported .NET Framework API, you might still encounter compatibility issues. Even so, this will help bridge the gap between .NET Core and many class libraries.
• .NET Framework features are missing. .NET Core still lacks some .NET Framework functionality. Pl note that Entity Framework Core and Entity Framework v6 are not the same.
• Require to Access Windows-specific APIs. In addition, .NET Core does not support any Windows specific APIs like WMI, Registry, and others. It is designed to be more sandboxed away from the OS.
• VB.NET and F# are partially supported. Despite Microsoft’s and the community’s efforts, the patch is not 100% complete.
• There is no support for SignalR. This feature will be included in .NET Core 2.1.

Developers Should Use .NET Framework When…

Windows comes with the .NET Framework. With .NET workflow tools and data connection methods, it is generally used to develop desktop Windows apps and large-scale enterprise applications.

The company offers services such as:

• Memory management
• Networking
• Type and memory safety
• Data structures
• APIs
• Security
• Application deployment

When it comes to using it, it’s most useful when configured to use Docker or Windows Containers…

• The program has already been used. Extend the application rather than migrate. ASP.NET Core developers can create new web services for example.
• The libraries or NuGet packages you are using aren’t compatible with .NET Core. While .NET Core is becoming more widely used, if you wish to work with libraries that are not compatible with .NET Framework, it is best to use .NET Framework. Therefore, Microsoft’s NuGet package manager is free and open source. As a result, packages can be generated and consumed using client tools that are part of the NuGet ecosystem. Furthermore, authors and users can access a central package repository. Visual Studio extensions are available for it.
• .NET Core doesn’t yet support these technologies. The .NET Framework is not fully supported. There are several technologies that aren’t available yet:
  • Applications written in ASP.NET Web Forms (no plans to port)
  • (Future plans include a port to ASP.NET)
  • Implementation of SignalR as a server and client for ASP.NET (Plans for porting)
  • Implementation of WCF services (we don’t plan to migrate, but we are considering it)
  • Workflow related services (no plans to port) including Windows Workflow Foundation (WF), Workflow Services (WCF + WF in a single service), and WCF Data Services (formerly known as “ADO.NET Data Services”)
  • Windows Presentation Foundation (WPF) and Windows Forms (no plans to port)
  • Visual Basic and F# (both to be supported in Visual Studio 2017.

• .NET Core is not supported on this platform. There are some Microsoft and third-party platforms that do not support it, such as Azure’s services. Eventually, however, many will implement support. As a result, as developers, you are aware that even supported services may present some issues. Henceforth, there are more tutorials and workarounds for .NET Core problems nowadays as the technology gains momentum. A few months ago, we encountered a 502.5 Process Failure when attempting to start an Azure App Service, so we wrote a post offering guidance for others experiencing the same issue.

When Not to Run .NET Framework

Do not run .NET Framework in the following situations:

• When use of multiple operating systems is there
• We need scalability and high performance
• .NET Core should work
• Need Open source frameworks

 Xamarin

The Xamarin platform lets developers create apps for iOS, Android, and Windows Phone. Thus, Visual Studio includes Xamarin in all editions. As a result, Xamarin is Microsoft’s way of creating a user interface (UI) and optimizing performance across hundreds of platforms. It is important to support Android and iOS devices when apps must run on both.

If you are interested in developing your app, then read here how much is the cost involved in developing a mobile app.

Therefore, to decrease time to market and engineering costs, Xamarin shares code across platforms and uses a single technology stack. Nevertheless, platform-specific coding may be required for user interface intensive apps. As a result, we save less and share less code.

More .NET Platforms on .NET Standards

.NET Standards support the following platforms in addition to .NET Framework, .NET Core, and Xamarin:

• Mono — A version of .NET that was open-source before Xamarin and Microsoft got together. In addition to C#, it takes advantage of the Common Language Infrastructure. Apart from C#, developers are able to use VB8, Java, Python, Ruby, Eiffel, F#, and Oxygene.
• Universal Windows Platform — Windows 10 Mobile, Xbox One, and Windows 10 software platforms are all devices supported by Microsoft’s Devices such as Windows 10 One, IoT and Hololens are part of the Windows 10 software platform. XAML, C++, C#, and VB.NET are among the development tools at the developer’s disposal.
• Supports Windows — versions 8.0 and 8.1
• Windows Phone — Originally developed for consumers, Windows Phone has been replaced by Windows 10 Mobile.
• Windows Phone Silverlight — Designed for running internet applications, it competed with Adobe Flash.

This common set of APIs replaces portable class libraries (PCLs). As a result, you must implement them in every platform. Therefore, this allows you to share code across desktop applications, mobile applications, and cloud services.

.NET 5.0 — The Next Step on the Microsoft Roadmap

By creating .NET 5 (without “core” or “framework”), Microsoft combined .NET Framework, .NET Core, and Xamarin Development into one platform. Therefore, with it, web development services will become easier to use. The gap between .NET Framework and .NET Core will, therefore, no longer exist in the coming years, so there won’t be a .NET Framework vs .NET Core war.

Is .NET Core Dead?

.NET Core 5 comes after .NET 3.1. For the following two reasons, Microsoft chose to name the new release .NET 5 and not .NET Core 4.0:

• DO not confuse .NET Framework 4.x with this version
• By dropping the word ‘Core’, it signifies that this will be .NET’s main implementation moving forward.

In addition, .NET 5 doesn’t replace the .NET Framework, which is still available. Therefore, we can conclude that .NET Core and .NET Framework not going to extinct any sooner, and that .NET 5 is an extension of .NET 3.

Prefer .NET 5 in the following cases:

• As a cross-platform user, you have requirements.
• It’s a microservices architecture you’re aiming for.
• Docker is what you are using.
• System performance must be high and scalability must be high.
• Per application, require separate versions of .NET

Conclusion: .NET Core vs .NET Framework

One important decision is to decide the framework you will use to build your applications with. When the default .NET Framework came there was very little choice. Application development has experienced an increase since the introduction of .NET Core. As a result, the open-source and cross-platform capabilities of the platform add flexibility and shareability for building robust applications.Hope, with this article you are clear about .NET Core vs .NET Framework, and know which is best to use for your runtime application.

On the other hand, Microsoft has an entirely different futuristic plan. Now, going forward it’s just .NET, with no cognomens at all. Therefore, you will need to determine which of these three Microsoft frameworks best fits your business needs.
