        <block subset="none" type="note">The <see cref="T:System.Runtime.InteropServices.InAttribute" /> and <see cref="T:System.Runtime.InteropServices.OutAttribute" /> are not required. In
   the absence of explicit settings, the system assumes that all arguments
   passed by reference are passed <see langword="in" />/<see langword="out" /> and that
   all non-reference parameters are <see langword="in" />. The only exception is the
<see cref="T:System.Text.StringBuilder" /> class, which is always assumed to be 
<see langword="in" />/<see langword="out" />. The <see cref="T:System.Runtime.InteropServices.InAttribute" /> and <see cref="T:System.Runtime.InteropServices.OutAttribute" /> are 
   particularly useful when applied to formatted types that cannot be block-copied.
   Since these types require copying during marshaling, you can use
<see cref="T:System.Runtime.InteropServices.InAttribute" /> and <see cref="T:System.Runtime.InteropServices.OutAttribute" /> to eliminate the generation of unnecessary
   copies.</block>

      <para>Compilers are required to not preserve this type
   in metadata as a custom attribute. Instead, compilers are required to emit it
   directly in the file format, as described in Partition II of the CLI
   Specification. Metadata consumers, such as the Reflection API, are required to
   retrieve this data from the file format and return it as if it were a custom
   attribute. </para>
