Hello,

I do not want simply regenerate and overwrite existing mapping files for unchanged tables in my db.

I am using Update Model From DB option. (NHibernate as ORM tool and MS SQL as database)

The problem is that even i set the option OverwriteMode.None or OverwriteMode.Merge in the customized template file, each time I create a new table and choose the option Update Model From DB, existing mapping files (.hbm.xml) that are not modified in the DB are also regenerated??

Please suggest

Settings for the mapping generation (OverwriteMode) is defined in the "Xml mapping generation" section (line 743). In case, you set it to OverwriteMode.None, only new mapping files will be generated. Changes, made to these tables, which are included in the model already, will not be added to the existing mapping files.
As for the OverwriteMode.Merge, we have reproduced the issue with it and fixed it. The fix will be included in the next build of Entity Developer.

Thanks for the answer

So i am waiting for the next fix.
