westonpace opened a new issue, #36506:
URL: https://github.com/apache/arrow/issues/36506
### Describe the bug, including details regarding any error messages,
version, and platform.
We specify the calling convention with:
```
internal delegate* unmanaged
#if !NET5_0_OR_GREATER
[Stdcall]
#endif
<CArrowArrayStream*, CArrowSchema*, int> get_schema;
```
Here is my understanding:
* These functions are implemented in Arrow-C++ When we build Arrow-C++ we
do not specify any calling convention (e.g. `/Gd, /Gr, /Gv, /Gz`) and therefore
the default (`/Gd`) will be used which maps to `__cdecl`.
* In the above, if we are < .NET 5.0 then it specifies `[Stdcall]`, which
is wrong
* In the above, if we are >= .NET 5.0 then it specifies the default, which
will be `[Stdcall]` on Windows, which is wrong.
In practice, this doesn't affect us because this only matters on 32-bit
machines
