            // Length ... Number of bytes allocated to hold version string (including null terminator), call this x.
            //            Call the length of the string (including the terminator) m (we require m <= 255);
            //            the length x is m rounded up to a multiple of four.

                SerializeStreamHeader(ref offsetFromStartOfMetadata, sizes.StandalonePdbStreamSize, "#Pdb", builder);
            }

            // Spec: Some compilers store metadata in a #- stream, which holds an uncompressed, or non-optimized, representation of metadata tables;
            // this includes extra metadata -Ptr tables. Such PE files do not form part of ECMA-335 standard.
            //
            // Note: EnC delta is stored as uncompressed metadata stream.
            SerializeStreamHeader(ref offsetFromStartOfMetadata, sizes.MetadataTableStreamSize, (sizes.IsCompressed ? "#~" : "#-"), builder);

            {
                SerializeStreamHeader(ref offsetFromStartOfMetadata, 0, "#JTD", builder);
