c# - Entity Framework - Manual Updates to edmx file overwritten with DB update -



c# - Entity Framework - Manual Updates to edmx file overwritten with DB update -

in entity framework, understand if create changes automatically created classes, lose chages on kind of db update. so, due you, create changes these objects in separate file using partial class syntax.

in similar way, had alter actual .edmx file manually add together in defining query described here.

now, when go add together in new tables db, of changes made edmx file lost , start getting errors in project.

is there way similar edmx file? - maybe create sec xml under same namespace hence append on @ load-time? and, if so, there examples of how this? ef brand new me , beating me much more thought :)

thanks!!

you can create partial class model main file. there class name yourmodel.context.cs(vb). can create class out of model , create class partial class, , customizations in partial class, otherwise loose customization on each model update.

c# .net vb.net entity-framework edmx
