What is NET Core
.NET Core, a powerful and versatile framework developed by Microsoft, has revolutionized the world of software development. It’s an open-source, cross-platform framework that allows developers to build high-performance, scalable applications for Windows, macOS, and Linux. Unlike its predecessor, the .NET Framework, .NET Core offers greater flexibility, modularity, and efficiency. This makes it a popular choice for building everything from web applications and microservices to cloud-based solutions and mobile backends. So, what exactly is .NET Core, and why should you consider it for your next project? Let’s dive in and explore the key features and benefits that make it such a compelling choice for developers today.
Cross-Platform Compatibility
.NET Core’s cross-platform nature is a game-changer. Developers can write code once and deploy it across multiple operating systems, eliminating the need to rewrite applications for different platforms. This saves valuable time and resources, streamlining the development process and reducing overall costs. This interoperability is achieved through the .NET Standard, a formal specification of .NET APIs that are available across different .NET implementations.
This cross-platform capability opens doors to new markets and opportunities for developers. It allows businesses to reach a wider audience without incurring the expenses associated with platform-specific development. Whether you’re targeting Windows, macOS, or Linux users, .NET Core empowers you to build robust and performant applications that cater to diverse needs.
For instance, a company developing a web application can use .NET Core to create a single codebase that runs seamlessly on both Windows servers and Linux containers, optimizing infrastructure costs and simplifying deployment.
Open Source and Community Driven
Being open-source, .NET Core benefits from a vibrant and active community of developers who contribute to its evolution. This collaborative environment fosters innovation and ensures that the framework continuously improves, adapting to the changing needs of the software development landscape. The open-source nature also promotes transparency and allows developers to inspect, modify, and contribute to the source code, enhancing trust and security.
This community-driven development model ensures that .NET Core remains cutting-edge and incorporates best practices from a diverse range of experts. The open nature of the project also means that developers have access to a vast library of resources, tutorials, and support forums, making it easier to learn and troubleshoot issues.
Performance and Scalability
.NET Core is designed for high performance and scalability, making it ideal for demanding applications. It features a highly optimized runtime and just-in-time (JIT) compilation, resulting in faster execution speeds and improved resource utilization. Furthermore, .NET Core’s modular architecture allows developers to include only the necessary components, reducing the application’s footprint and improving performance.
Scalability is crucial for modern applications, and .NET Core excels in this area. Its architecture enables applications to scale horizontally, distributing the workload across multiple servers to handle increased traffic and demand. This allows businesses to easily adapt to growth and ensure that their applications remain responsive even under heavy load.
According to TechEmpower benchmarks, .NET Core consistently ranks among the top-performing web frameworks, demonstrating its ability to handle high volumes of requests with efficiency.
Modular Design and Flexibility
.NET Core’s modular architecture allows developers to choose and include only the components they need, reducing the application’s size and dependencies. This “pay-as-you-go” approach simplifies development and deployment, making it easier to manage and maintain applications over time. This flexibility also allows developers to integrate .NET Core with other technologies and frameworks seamlessly.
This modularity contributes to improved performance and reduces the attack surface of applications, enhancing security. It also allows developers to adopt new features and updates incrementally, without having to overhaul entire systems. This makes .NET Core a future-proof choice for building applications that can adapt to evolving technologies.
Key Benefits of .NET Core:
- Cross-platform compatibility

Question & Answer :
Recently in an official .NET Framework Blog it was announced that .NET Core is going open source.
Ironically, the author mentions that what .NET Core is will be explained in the next post. Some more details are mentioned in another announcement post.
From a supplied diagram:
and articles text itself, I would assume that .NET Core (beside obvious things like being open-sourced) is a modular re-implementation of the full .NET. I.e. framework components are loaded as necessary, much like NuGet packages are loaded now. And now ASP.NET 5 is one of the modules that is already implemented. Is my understanding of .NET Core correct? Maybe I’m missing something?
I have found a recent article which I found both short and very good. It covers .NET Standard, .NET Core, and .NET Framework and their relationship. I highly recommend it.
From the .NET blog Announcing .NET 2015 Preview: A New Era for .NET:
.NET Core has two major components. It includes a small runtime that is built from the same codebase as the .NET Framework CLR. The .NET Core runtime includes the same GC and JIT (RyuJIT), but doesn’t include features like Application Domains or Code Access Security. The runtime is delivered via NuGet, as part of the [ASP.NET Core] package.
.NET Core also includes the base class libraries. These libraries are largely the same code as the .NET Framework class libraries, but have been factored (removal of dependencies) to enable us to ship a smaller set of libraries. These libraries are shipped as System.* NuGet packages on NuGet.org.
And:
[ASP.NET Core] is the first workload that has adopted .NET Core. [ASP.NET Core] runs on both the .NET Framework and .NET Core. A key value of [ASP.NET Core] is that it can run on multiple versions of [.NET Core] on the same machine. Website A and website B can run on two different versions of .NET Core on the same machine, or they can use the same version.
In short: first, there was the Microsoft .NET Framework, which consists of a runtime that executes application and library code, and a nearly fully documented standard class library.
The runtime is the Common Language Runtime, which implements the Common Language Infrastructure, works with The JIT compiler to run the CIL (formerly MSIL) bytecode.
Microsoft’s specification and implementation of .NET were, given its history and purpose, very Windows- and IIS-centered and “fat”. There are variations with fewer libraries, namespaces and types, but few of them were useful for web or desktop development or are troublesome to port from a legal standpoint.
So in order to provide a non-Microsoft version of .NET, which could run on non-Windows machines, an alternative had to be developed. Not only the runtime has to be ported for that, but also the entire Framework Class Library to become well-adopted. On top of that, to be fully independent from Microsoft, a compiler for the most commonly used languages will be required.
Mono is one of few, if not the only alternative implementation of the runtime, which runs on various OSes besides Windows, almost all namespaces from the Framework Class Library as of .NET 4.5 and a VB and C# compiler.
Enter .NET Core: an open-source implementation of the runtime, and a minimal base class library. All additional functionality is delivered through NuGet packages, deploying the specific runtime, framework libraries and third-party packages with the application itself.
ASP.NET Core is a new version of MVC and WebAPI, bundled together with a thin HTTP server abstraction, that runs on the .NET Core runtime - but also on the .NET Framework.
