Best way to integrate into .NET #57

Open onacrame opened 8 months ago

onacrame commented 8 months ago

I'm looking for the best way to integrate a compiled model into .NET code. I'd rather not have to utilise an initial call to Python and rely on the underlying binary. I know there's reference to example in the benchmark section but not sure what adaptations are required to make it work outside of that context

I'm not familiar with .NET at all sadly. Though the process should be the same as calling any C function, so an approach like this one should work for you. All that's necessary is declaring the function as extern, and passing the path to the binary returned by lleaves to your linker.
