Generic conversion of managed delegate to native function pointer

Is there a way to generalize the conversion of a managed ,NET delegate to a C++ function pointer?

I created this function template for the moment:

template<typename TManagedDelegate, typename TNativeFunc>
TNativeFunc CreateFunctionPointer(TManagedDelegate^ del)
{
    using namespace System::Runtime::InteropServices;
    GCHandle gch = GCHandle::Alloc(del);
    IntPtr ip = Marshal::GetFunctionPointerForDelegate(del);
    return static_cast<TNativeFunc>(ip.ToPointer());
}

but this requires the call site to explicitly indicate the types:

using NativeFuncionPointer = void(*)();
System::Action^ action;
NativeFuncionPointer fp = CreateFunctionPointer<System::Action, NativeFuncionPointer>(action);

My goal is to have a way to call:

System::Action^ action;
auto fp = CreateFunctionPointer(action); //type of 'fp' deduced to 'void(*)()'
