Hi Alfred Ortega,
Although the Reverse mapping wizard did not generate the version field or the VersionField property in the Persistent attribute, the right mapping entries were made in the app.config file.
This behavior is improved in the Q3 release. The version field is now generated by default (this can be switched off) and the right mapping entries are made to the app.config file, so you do not need to manually modify the code to add the version field anymore.
