❔ Is `where` still used?

private static byte[] StructToBytes<T>(T data) where T : struct
{
    byte[] rawData = new byte[Marshal.SizeOf(data)];
    GCHandle handle = GCHandle.Alloc(rawData, GCHandleType.Pinned);
    try
    {
        IntPtr rawDataPtr = handle.AddrOfPinnedObject();
        Marshal.StructureToPtr(data, rawDataPtr, false);
    }
    finally
    {
        handle.Free();
    }

    return rawData;
}
