Best .NET libraries β€” Top useful libraries every .NET developers use

.NET Core has become one of the most popular frameworks for developing modern applications. One of the reasons for its popularity is the wide range of libraries available to developers. .NET Core got new updates in its features with lesser coding, deploying high-accomplishment, and extremely scalable applications. Making the underlying architecture functions more effective and efficient without having to reinvent the wheel will free up your time to focus on more crucial tasks, including making your application stand out from the competition.

In this article, we'll take a closer look at The Most Popular .NET Libraries Every Developer Should Know. As a software developer, you're likely familiar with the .NET framework and the many libraries it offers. With so many options available, it can be overwhelming to know which ones to choose for your project. This is the main reason I have compiled a list of the Top 10 .NET Libraries That Developers Should Use to make their development process more efficient and effective. A list of Top 10 .NET Core Libraries will let developers understand these so that they can pick appropriate libraries for their projects.

If you're a .NET Core developer, there are 10 important .NET Core libraries that you should be familiar with. While creating these Essential 10 .NET Libraries Every Developer Must Know, I used NuGet and popular repositories. And all the libraries listed here are also open-source. The list is filtered with only to .NET Core related libraries. Also I excluded the Microsoft .NET Core Framework libraries from this Top 10 Unique .NET Core Libraries Developers Must Utilize. So, without further ado, let’s get right into it:
