Nullable reference types in C# help us safely manage references.
The compiler has checked these assignments, and they are safe.
Assigning a nullable reference to a non-nullable variable raises a warning.
The null coalescing operator helps ensure that the right-hand side is never null.
A dereferencing attempt also raises a warning.
Null propagation operator helps mitigate the danger.
Finally, combining the two operators ensures no null error can pass.
But what if there is a method that does not accept, nor produce, a null?
There is no operator for calling such a method.
A custom extension method can bridge the gap.
Check the input reference and optionally apply the method.
This call is now safe.
We can also clear all nulls the null coalescing operator.

👨 About Me 👨
Hi, I’m Zoran, I have more than 20 years of experience as a software developer, architect, team lead, and more. I have been programming in C# since its inception in the early 2000s. Since 2017 I have started publishing professional video courses at Pluralsight and Udemy and by this point, there are over 100 hours of the highest-quality videos you can watch on those platforms. On my YouTube channel, you can find shorter video forms focused on clarifying practical issues in coding, design, and architecture of .NET applications.❤️
