C# 13 finally eliminates the hidden array allocation behind params. You can now use params with Span, ReadOnlySpan, List, and other collection types for zero-allocation variadic methods.

C# 13 extends the params modifier beyond arrays to support Span, ReadOnlySpan, IEnumerable, and other collection types, reducing boilerplate and improving flexibility.

How to fix 'Feature is not available in C# 12.0' and switch your project to C# 13 by changing the target framework or setting LangVersion in your .csproj file.
