#Net5 – C#9 logical operators “is” and “is not” are super cool 🆒🆒🆒

Hi !

In the line of good features, that are also nice to read, the new use of is and is not is a huge improvement in readability.

As usual, old school validation for objects and types:

// old school
if(!(testObj is MyClass)) {...}

And now, we can type the validation with some style:

// C# 9 style
if(testObj is not MyClass) {...}

I like this new one 👆, now null / not null and other validations will be the same. With an improed readability !
