Only keep used types and remove unused types

Question

Is there any way to remove unused types/code from a project. lets say I'm using NAudio(source code) in my console application and I'm only using the WaveIn class from it. Is there any way for me to remove unused classes from the code and only keep the WaveIn class and the classes WaveIn depends upon? Something down the line of tree shaking

You mean remove it from a compiled assembly? Not without recompiling the assembly. — Lasse V. Karlsen, Aug 08 '16 at 06:44
Why do you feel a need to do this, what problem are you hoping to solve? — Lasse V. Karlsen, Aug 08 '16 at 06:44
Sorry, I didn't read your question well enough, my bad, early monday not enough coffee. I don't know of any such tool other than *perhaps* ReSharper which will flag a class as unused but it may not actually give you any help here since presumably there are many classes that uses each other, it's just that *your program* does not use them. — Lasse V.

Ndepend was the answer

from t in Types 
let depth0 = t.DepthOfIsUsedBy("NAudioTrim.Program")
where depth0  >= 0 orderby depth0
select new { t, depth0 }

where NAudioTrim.Program contains the entry point of my application and contains the used types. Once you get the list of all used types and the types they use you can delete the rest of the files/types

What is Types in this case? You you map from Type to IUsed interface required by DepthOfIsUsedBy method – Vlado Pandžić Feb 08 '23 at 13:27
