c# - Updating ado.net entity data model without effecting model classes already in EDMX -


i have done lot of attribute validation on models in edmx entity data model class .but time of updating adding new table ado.net entity data model automatically removed attributes given.

is there way update newly added table model class without effecting other models customized..

the bad point have worked on auto-generated code.

but lucky, if observe more attention model classes should see partial classes can extend classes in files , put attribute respectively on each 1 , won't affected generation of edmx.

try , give result ;-)
