What are some advanced types in C# and their use cases?

In C#, advanced types include tuples, records, and nullable types. Tuples allow you to group multiple values, records provide a concise way to define immutable data types, and nullable types enable you to assign null to value types.

Can you give me an example of using tuples?

Sure! You can create a tuple like this: var person = (Name: "John", Age: 30);. You can access the values using person.Name and person.Age.

What about records? How do they differ from classes?

Records are similar to classes but are designed for immutable data. They automatically provide value-based equality, meaning two records with the same data are considered equal, unlike classes which use reference equality.

Are there any performance considerations with using these advanced types?

Yes, while advanced types like tuples and records are convenient, they can introduce overhead. For example, tuples may be less performant than arrays for large collections, and records can have a higher memory footprint due to their immutability.
