System.TypeLoadException: 'Could not load type 'LLama.Native.NativeApi' from assembly 'LLamaSharp,

[CommanderLake]

I built my own llama.cpp b4743 which works fine with LM Studio but when loading a model with LLamaSharp i get this:
System.TypeLoadException: 'Could not load type 'LLama.Native.NativeApi' from assembly 'LLamaSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' because the method 'llama_backend_free' has no implementation (no RVA).'

llama_backend_free exists with the correct signature and is properly exported and both are compiled as x64.

I am limited to Visual Studio 2017.

Any given version of LLamaSharp only works with exactly one version of llama.cpp. Check the table at the bottom of the readme for the exact version you need.
