@Shervan360, Welcome to Microsoft Q&A,

what is IOptions interface

the IOptions interface is part of the .NET Core, which provide strongly-typed access to groups of related settings, such as appsettings.json, appsettings.{Environment}.json, environment variables, command line arguments, etc.

If you want to make a code example, you could refer to the Microsoft Learning Options pattern in .NET.

when and why I should use it

I guess that you want to know the benefits of using IOptions interface. Here are some points you could refer to.

a. You could use IOptions interface to separate configuration data from code, which makes it easier to change configuration data without having to modify your code.

b. IOptions supports reading configuration data from multiple sources

c. IOptions can be easily integrated with the .NET Core dependency injection system, which makes it easy to inject configuration data into your classes.

Hope my explanations could help you.

Best Regards,

Jack
