Introduction

MonoDetour is mainly designed to be used with HookGen. That is, MonoDetour generates helpers hooks to make hooking easy.

You can use the generated hooks like so:

// Generate helper hooks for the target type.
[MonoDetourTargets(typeof(SomeType))]
class SomeTypeHooks
{
    // MonoDetourManager.InvokeHookInitializers will
    // call methods marked with this attribute in types
    // which have the MonoDetourTargetsAttribute.
    [MonoDetourHookInit]
    internal static void InitHooks()
    {
        // Note: this is using the default generated MonoDetourManager
        // MonoDetour.HookGen.DefaultMonoDetourManager.Instance by default.
        // Use it for managing your hooks.
        On.SomeNamespace.SomeType.SomeMethod.Prefix(Prefix_SomeMethod);
    }

    private static void Prefix_SomeMethod(SomeType self, ref int number)
    {
        Console.WriteLine("Hello from Prefix hook!");
    }
}

MonoDetour entirely relies on ILHooks for hooking similar to HarmonyX. But instead of having monolithic ILHook methods like in HarmonyX, MonoDetour maps every hook to a unique ILHook.
