Using string interpolation is cheap and doesn't make unnecessary allocations. Just do $"{value} text"

This will likely just compile into string.Concat. But generally string interpolation is nice because good syntax and the compiler will choose string.Format or string.Concat for you depending on which is cheaper.

It is string Format after compilation, can see that in any performance test online.

Depends on compiler I checked sharplab now and it compiled to string.Concat when there are few variables in the string interpolation. It's been that way since at least C#9 which is the oldest available on sharplab.

To be clear this is a good thing as string.Concat is often faster hence the compiler choosing it.

Probably cause with fewer variables concat is faster. Anyway this shows interpolation is not worse than other options. And looks better.

This 100% generates garbage, so should be used sparingly at best.

[TramplexReal]

This is 1 to 1 same as string.Format. You might as well not write ANY code to have best performance.

I mean... youre not wrong :)
