    <summary>Disables the built-in runtime managed/unmanaged marshalling subsystem for P/Invokes, Delegate types, and unmanaged function pointer invocations.</summary>
    <remarks>
      <format type="text/markdown"><![CDATA[

## Remarks

The built-in marshalling subsystem has some behaviors that cannot be changed due to backward-compatibility requirements. This attribute allows disabling the built-in subsystem and instead uses the following rules for P/Invokes, Delegates, and unmanaged function pointer invocations:

- All value types that do not contain reference type fields recursively (`unmanaged` in C#) are blittable.
- Value types that recursively have any fields that have `[StructLayout(LayoutKind.Auto)]` are disallowed from interop.
- All reference types are disallowed from usage in interop scenarios.
- SetLastError support in P/Invokes is disabled.
- varargs support is disabled.
- LCIDConversionAttribute support is disabled.
