how bind std::vector<CustomStructure> ?

Hi, I'm trying to send an array of a custom structure to mono, how would I be able to do this?

c++
```c++
std::vector vec;
method.invoke_instance)>(object, vec);
```
I've already made the converter for this structure, but I don't know how to make the signature to use an array because the method is not found in c#

c#
```c#
public void OnData(ns2.CustomStructure[] data)
{
Console.WriteLine($"OnData: ${data.Length}");
}
```
the signature: `Test::OnData(ns2.CustomStructure[])`

if i use inside my namespace, i get `* Assertion at ..\mono\metadata\object.c:1938, condition 'klass' not met`

I would also like to understand more about `std::vector / std::array` > `any_type[]`, `any_type` is my type ?

Start by tracing method.invoke_instance and the existing CustomStructure converter, then compare them with the C# OnData(ns2.CustomStructure[] data) entry point and the Test::OnData(ns2.CustomStructure[]) signature. Determine how array arguments are represented and resolved; done means the C# method is found and receives the vector data without the reported Mono assertion.
