Managed Array Fields

How do I get arrays from fields?

At first I thought something like this would do the trick:
Coral::Array<int> arr = managedObject.GetFieldValue<Coral::Array<int>>("IntArrayField");
but arr always has a length of 0.

I also looked at the examples and tests but couldn't find what I needed.

I'll probably be merging dev to main in a month at most

Hey, I'm sorry I forgot to mention I was working with Coral on the dev branch.

I'm using the Testing project inside Coral for demonstration. This is what happens when I try to retrieve the field IntArrayTest:

I think I might have found out what is going on.
I pinned down the problem to the method MarshalReturnValue in the Marshalling class, specifically if the type is a one dimesional array:

Even though fieldArray is a GCHandle to an Array object, for some reason AddrOfPinnedObject returns a pointer to the start of the array's data. The array's length however is an 8 byte integer right before that (used visual studio's memory view to find that out). So I did this:

Just used the ArrayContainer struct to add the length and:
