While the tech world awaits .NET 8, it’s an opportune moment to take a step back and reflect on the transformative journey of C# and .NET. Their evolution was not just a testament to Microsoft’s vision but also the dynamic and ever-changing demands of developers worldwide. This article offers a whirlwind tour of their metamorphosis, highlighting key milestones, and setting the stage for the exciting innovations .NET 8 promises to bring.
How it all began
.NET Framework 1.0
Released in 2002, .NET Framework 1.0 was Microsoft’s answer to a changing software development landscape, aiming to provide a unified environment for developing web services, desktop applications, and other software. The first release included many of the key features that are still being used today, even if they’ve changed as time went by, these were:
CLR: Common Language Runtime
BCL: Base Class Library
Windows Forms: For building rich desktop applications and even with the release of WPF or .NET MAUI they’re still being used
Support for multiple languages: One of the main advantages was its ability to support multiple languages, ensuring interoperability
As you can see, even though .NET platform is constantly changing and evolving, the key features were a fundament for what we have today, which is being polished to this day. We’ve talked about the platform and now you might be wondering what did C# 1.0 had to offer back then.
Introduced alongside .NET Framework, C# 1.0 became one of the primary languages designed for the platform. Anders Hejlsberg, who also worked on Turbo Pascal and Borland Delphi, was a chief architect behind C#. As you may guess, C# 1.0 was not so rich in features as today, but in the same way as .NET Framework 1.0, it already had all the key concepts included that we’re still using to this day and they’re nowhere to go.
Object-Oriented: Full support for classes and the three pillars of Object-Oriented programming (inheritance, polymorphism, and encapsulation)
Syntax, which was heavily influenced by Java and C++, but with a focus on simplicity and productivity, was also related to the next key feature
Garbage collection: Automatic memory management to avoid common programming pitfalls
Type-Safety: C# is designed to be strongly typed to minimize runtime errors and enhance performance
Declarative programming: Attributes in C# allow developers to add metadata to assemblies, classes, etc., which could be then queried at runtime using reflection
What has changed
Although .NET Framework and C# went a long way and there were a ton of features added year to year, the major change happened in November 2020, when .NET 5 was released. You might be asking, what did it change for us, developers? Well, let’s see:
Consolidation of .NET Core and .NET Framework: .NET 5 was a successor to .NET Core 3.1, it brought an end to the separate .NET Core branding. It’s not here to continue what .NET Framework is but to represent the path forward for the .NET platform as a whole.
Unified Platform for Different Workloads: .NET 5 allows developers to target various application types such as web, cloud, mobile, gaming, IoT, and AI using a single .NET platform.
Cross-Platform Support: .NET 5 maintained and improved upon .NET Core’s commitment to cross-platform development, enabling developers to run their applications on Windows, Linux, and MacOS.
All of this sounds pretty cool, although .NET 5 didn’t bring us any GUI development libraries that were cross-platform, and existing ones like WinForms or WPF remained Windows-only technologies.
In terms of major changes, there were not so many features offered with .NET 6/7 releases as in previous versions, but they both provided significant performance improvements and also, we finally have a technology for making GUI applications cross-platform, although, still not possible for Linux. What I’m talking about is — .NET MAUI, which is pretty good, but comes with some caveats.
Yes, you have a cross-platform GUI technology, but Linux is still missing out.
Yes, you have the ability for AOT compilation to run basically on bare metal, without .NET Runtime installed at all, but not for cross-platform apps, this is still a Windows-only feature.
And the last one, .NET MAUI is actually pretty good, but you have to write its styling and markup using HTML & CSS, which might be a plus for someone, although old C# developers might be more used to WinForms style or XAML.
What to Expect
Even though .NET 8 is set to release in November 2023, we already can try it out! Yes, the RC1 is already available and it has a lot to offer, including things like Native AOT for Web applications, Blazor improvements, and Entity Framework updates, make sure to check out all the benchmarks (really big performance improvements) and RC1 notes. From the revolutionary advancements in Web application development to performance leaps, .NET 8 promises a transformative experience for developers. So why wait? Dive into the RC1 today and be among the first to feel the power of the future of .NET!
