Tested with X64 architecture with non-inlined methods. (careful with optimized code with inlined methods, the pattern was not intended to be used in that case)

How to use:

1- Create a class that implements the interface IHookerHandler:

public class MyHookHandler : IHookHandler
    public void Before(object instanceHooked, object[] parameters)
        // do whatever you want here
    public void After(object instanceHooked, object[] parameters)
        // do whatever you want here

2- Get the methodInfo for the method to be hooked:

MethodInfo methodHooked = typeof(Foo).GetMethod("MethodHooked");

3- Hook the method!

HookManager.Instance.HookFunction(methodHooked, new MyHookHandler());

Or hook the method with lamdas (before call and after call)

HookManager.Instance.HookFunction(methodHooked, (t) => { ... }, (t) => { ... });

4 - (opt) When finished, you can unhook the method:
