What is .net core vs .net framework. The first launch of .NET Framework was in 2002, and over the years, it grew a huge set of APIs. On the other hand, .NET Core was introduced in 2016.
The .Net Framework is an immense and mature development platform to create Windows desktop, web, mobile, games, and IoT applications.
.NET Core, on the other hand, is an open-source .NET platform that allows you to build cross-platform applications; So your apps can run on Windows, Linux, and Mac OS.
We had the option to gain from the .NET Framework experience and overhaul the engineering of the stage to address a few impediments of the past. This resulted in better accomplishment for .NET Core and allowed us to add a few features not available on .NET Framework.
.NET Framework features:
- Let’s briefly talk about core-specific features of .NET Framework.
- You can install only one version of the Framework on the machine, used by all applications.
- This way, if you want to upgrade it to the latest version of the Framework, all applications using the same machine will depend on it. If you upgraded the .NET version on that machine, all the apps now use that upgraded version of .NET. This behavior might not be a good approach.
- For devs, it usually means that the .NET version upgrade was a company-wide decision performed by the technical department which sometimes slows down the upgrades.
.NET Core features:
- In .NET Core, you can have different versions of the .NET Core on the same machine. For each application, You can specify the .NET Core version you want to use.
- We can package .NET Core with our application and be fully independent of our application’s environment.
- For example, we can run our application on a Mac OS machine that has never used a .NET core installation previously. That gives us the freedom to upgrade the latest version of the .NET platform at our own pace and benefit.
- Besides these features, .NET Core has other huge improvements. You can read about them in the documentation.
Now let’s discuss what is included and not included in .NET and .NET Core.
- In the first instance, .NET Core was started as a small subset of the most used APIs from.NET. Whereas in .NET Core version 2 and 3, .NET Core received more APIs to cover web, Cloud, desktop, IoT, and AI.
- Some domains only exist in .NET on Windows and would not be migrated to .NET Core due to either architectural challenges or because we believe that these APIs are outdated, Windows-specific, or have the latest changes in .NET Core. In the future, all the latest feature APIs will go to .NET Core. Don’t worry .NET will still be supported and receive all appropriate and security updates. So it’s completely safe for enterprises and for us to leave applications on .NET.
- But if you want to use the latest language features and runtime improvements, you should migrate to .NET Core. That takes us to the answer to the frequently asked ultimate question.
Which one should I pick for my applications, .NET Core or .NET?
Let’s quickly summarize what we have just discussed.
So ultimately, what does .NET Core have that .NET doesn’t have?
- It will receive new features,
- APIs and runtime improvements.
- It has better performance.
- It can have different versions of .NET Core deployed at the same time on the same machine.
- You can create self-contained applications and become closely independent of the environment you’re running on and so on.
What does .NET have that .NET Core doesn’t have?
- .NET has few older APIs that will not be migrated to .NET Core.
How do you choose .Net core vs .Net Framework?
- For new applications, choose .NET Core.
- For your projects that are only in maintenance and all the development project, and you don’t want to change that code, it’s completely safe to leave them on the .NET Framework. For existing applications targeting .NET Framework but are in active development, you can make your call; either you move them to .NET Core or leave them on the .NET Framework.
- You can evaluate benefits and porting costs and make the decision that is best for your application.
