.NET Core- An overview

.NET language was introduced in 2002 by Microsoft. Previously it was used for Microsoft products only; and was closed-sourced, which means it will not allow developers to code or execute apps in Android, Linux, or iOS.

As this framework was only for Microsoft products and its usage was restricted to other products, .NET wasn’t acknowledged much in the past. However, in 2016, .NET Core was released in the market and changed the whole perception. In modern times, it’s giving tough competition to Java and many companies are efficiently using it to develop various software.

In the latest version of .NET core, it is made compatible with major operating systems. There are many basic .NET tools available with multiple libraries, third-party tools, and add-ons for creating customized apps for instant and immediate use. .NET core architecture abides with an OOP paradigm and is also used with multiple languages like C#, F#, C++, etc.

Pros and Cons of .NET Core

Here’s the list of potential advantages and risks associated with the .NET language. Have a look at them:

.NET Core: Advantages

  • This framework allows you to use different programming platforms like J#.NET, C#.NET, VB.NET, IRON RUBY, JSCRIPT.NET, WINDOWS POWERSHELL, etc.
  • .NET is a framework that is user-friendly and versatile
  • As per your business requirements, you can ask developers to use different combinations of programming languages to develop websites as per your specific needs.
  • There are a lot of advanced tools available in the Microsoft Developer Network that make the development process easier.
  • .NET Core avoids unnecessary coding and provides reusable components that help in enhancing the development process.
  • It is also easy to maintain the .NET code as it is small. At the same time, developers can also optimize this code easily only in a few statements.

.NET Core: Disadvantages

  • Tooling can be challenging when used. NET. In the regular update of Microsoft, when developers try to develop an app and try to search for the root cause of certain exceptions, it could be challenging and because of this, there can be regular updates in the documents of the latest framework.
  • The documentation of ASP.NET core isn’t essential as compared to various development technologies. As it is updated regularly, documentation also has to be changed repeatedly.

Java vs .NET Core: Differences

Here are some primary differences that one should keep in mind while studying Java vs .NET Core.

Coding Speed

When software developers pick Java programming language, they use different threads and ultimately simplify the project management and processing instructions in a proper sequence. However, when the factor of coding speed is considered, the .NET language is the leader in this matter.

Because of the object orientation, .NET offers several elements that are reusable. Hence, when you compare Java vs .NET core based on the time both languages take to develop identical apps, .NET will be less time-consuming.

Scalability

While developing complicated, enterprise-level, and large-scale apps, both frameworks are equally effective. Hence, both .NET and Java frameworks are quickly implemented to develop enterprise-level applications. Hence, choosing any one technology based on scalability will completely depend on your project requirements and business goals.

Performance
