The serializers generated by this program can handle almost anything including DataSet and DataTables. The serializers are platform neutral . They run equally well on Windows, Windows Mobile, Mono . The code generated by the studio is faster than standard binary by 10-50 times. Studio allows you to easily integrate your surrogates in the framework. Typical DataSet serialization is faster in avarage than standard binary by 10-12 times. The generated serializer can be used as a standalone serializer (typically as the part of DotNetRemoting Lib) or as a surrogate for the binary formatter.
