9 Key Differences between .NET and .NET Framework
.NET is an open-source platform with openly available source code. This implies that developers may view and customize the source code as needed, resulting in a more flexible development environment.
The .NET Framework is still mostly closed source, however several open-source components, such as Roslyn and ML.NET, could be used on both .NET and .NET Framework.
When it comes to performance, .NET and .NET Framework differ significantly. This is partly because .NET is built to be lightweight and efficient, with a smaller runtime and fewer dependencies. Moreover, it has been optimized to meet the demands of cloud-based applications, which often require high levels of scalability and performance.
Every year, a new version of .NET is released with numerous performance improvements. They are related to different areas of code compilation (new on-demand RyuJIT compiler, IL trimming), more effective memory management (improved algorithm for garbage collection), Regex execution improvements, and other algorithms used by developers.
On the other hand, updates to .NET Framework includes only security fixes. The latest major release of the .NET Framework, version 4.6, was unveiled in 2016.
.NET offers a highly adaptable deployment model. .NET uses its own web server called Kestrel, which is designed to be used with any other web server (as a reverse proxy) like IIS, nginx or Apache. In addition .NET applications could be easily hosted in Docker containers.
In contrast, .NET Framework can only be deployed on the Internet Information Server. The application’s flexibility is severely limited since it must be developed to operate on IIS and may not be compatible with other types of servers or hosting setups.
.NET Framework is limited to running exclusively on the Windows operating system. However, it is highly compatible with a wide range of third-party libraries and tools.
On the other hand, .NET is a cross-platform framework that was designed to work on multiple operating systems, including Windows, Linux, and macOS. Unfortunately, .NET may not be compatible with all .NET Framework libraries and tools, and some modifications may need to be made in order to ensure compatibility.
Support for WCF Services
The .NET platform doesn’t provide native support for creating WCF services. However, if clients of your service require SOAP protocol communication, you can utilize the open-source Core WCF project to build WCF services via .NET. It’s important to note that Core WCF offers only basic WCF features, so ensure that it meets all your requirements.
.NET Framework supports WCF services and also has support for REST services, although it does not offer much flexibility in designing or deploying microservices.
Support for Microservices
.NET has better support for microservices than .NET Framework. It was designed to be lightweight and modular, making it ideal for building microservices-based applications. It has built-in support for containerization and Kubernetes orchestration, which makes it easier to deploy and manage microservices in a distributed environment.
.NET Framework does not have the same level of support for microservices. While it can support microservices, it might demand the use of extra tools and frameworks to attain the same degree of flexibility and scalability as .NET.
Both .NET and .NET Framework place a strong emphasis on security; nonetheless, it’s crucial to acknowledge their disparities in terms of supported security features. The .NET Framework maintains compatibility with old legacy security features. While these features may still be effective, they may lack the incorporation of latest advancements and contemporary security measures found in .NET.
.NET, on the other hand, being the newer and open-source platform, is built on current security principles and includes robust security enhancements. Features like, role-based access control, data encryption, support for SSL/TLS protocol, ensure that applications built on .NET are safeguarded against potential vulnerabilities and threats.
When it comes to mobile development, .NET is the favored choice since it empowers the creation of cross-platform mobile apps employing frameworks such as Xamarin, allowing developers to write code once and distribute it on various platforms such as Android and iOS.
Since the .NET Framework is designed exclusively for Windows, it cannot facilitate mobile development.
Both .NET and .NET Framework support a variety of application types, including console, desktop, and web applications.
However, .NET extends its array of benefits to encompass the development of mobile native applications and microservices.
.NET and .NET Framework Similarities
Even though they have plenty of differences, they do share some similarities as well. Here are some of them:
- They both are Windows-based operating systems.
- They provide access to the .NET Standard library, which defines a set of APIs that are common across all .NET implementations.
- Both provide significant object-oriented programming support and share concepts such as base class library.
