Running a simple example and I get : System.EntryPointNotFoundException Unable to find an entry point named 'llama_init_backend' in DLL 'libllama'.

I've installed :
LlamaSharp : 0.4.0
LlamaSharp.Backend.Cpu : 0.4.2-preview

With the following example :

string stModelPath = @"pathfoo\llama-2-7b-guanaco-qlora.ggmlv3.q4_1.bin";

var ex = new InteractiveExecutor(new LLamaModel(new ModelParams(stModelPath, contextSize: 1024, seed: 1337, gpuLayerCount: 5)));

I get this crash shortly :

The type initializer for 'LLama.Native.NativeApi' threw an exception.

System.EntryPointNotFoundException

I've looked into issue #2 and seen that installing the module worked.
I've verified that the two nuget packages are installed under .nuget and that libllama.dll does exist in runtimes\win-x64\native

Any suggestions on how to proceed?

You've installed 0.4.0 of the main package and 0.4.2-preview of the backend package - these aren't compatible! Make sure you always use the same version of both.
