ASP .Net Core makes it easier for developers working on software development with .Net technologies to develop more responsive, reliable, and extensible applications.

ASP .Net Core has redesigned the .Net infrastructure and combined it with Web API and MVC infrastructure.

.NET Core Features
• Performance: There are many libraries and optimization tools, and sustainable and high-performance software can be created. Many infrastructures such as fast releases, easy updates, memory optimizations make it usable in mobile.
• Cross-Platform — Container Support: Applications designed with .Net core work smoothly on all platforms such as Windows, Linux, macOS with this feature we call Cross-platform. Container, which we call virtualization at the operating system level, is widely used in the cloud world. It supports Kubernetes, Dockers, and other technologies.
• Open Source Code Flexibility: When we want to add or remove infrastructure to our project, it allows us to make the necessary changes without having to re-establish the infrastructure.
• Dependency Injection Support: While this feature could be accessed with external applications such as AutoFactor or injected in previous versions, there is no need for external software now.
• Simple Unit Testing Support: Visual Studio Testinginfrastructure was replaced with xUnit.net along with .Net Core infrastructure. In this way, there is now a suitable environment for writing unit tests.
• Easy update: As a .Net developer in old versions, it was quite difficult to get new updates. However, with .Net core we get the updates with the NuGet packages that handle every update.
• Creating Web Applications: It supports the creation of .Net core IoT applications, cloud-based applications, web applications, and many more services when new technologies are desired to be immediately integrated into projects and used in processes.
