Today we are going to discuss three features from C# 9.0. In order to use C# 9.0 and .NET 5.0, we should have Visual Studio 16.8 or above. As you might have already know .NET is the next version from .NET Core 3.1. The reason .NET 5.0 was chosen so that there is no confusion with the .NET version 4.* and Microsoft wanted to get rid of the Core because going forward this is the .NET version. Though for ASP.NET it is going to be still named as ASP.NET Core 5 because there is already AP.NET MVC 5.0. Here to avoid confusion, Core is retained. Same is applicable for Entity Framework Core. Entity Framework 5.0 will be named as Entity Framework Core 5 because there is already EF 5.0 and EF 6.0. Let us dive into features.
