C# (pronounced "See Sharp") is a modern, object-oriented, and type-safe programming language. C# enables developers to build many types of secure and robust applications that run in .NET. In 2023, C#   introduced  several exciting features. With the introduction of the collection expressions feature in C# 12, you can now use a more concise syntax when creating collections such as arrays, lists, and dictionaries.

C# 12 includes yet another exciting feature known as interceptors. Interceptors can help you to replace or intercept a method call with an alternative method. You can use this feature to reroute method calls without changing the original piece of code. With C# 12, now you can declare an inline array to work with a memory block without using the unsafe keyword.
