Bhaskar Shelar

In Existing project implementation done from edmx model first approach EF I have to use Code First approach . In existing project ,It creating Using repository BO ,base Bo ,Enum classes . Have to reflect the same with just change in approach.

In Exiting they used ObjectContext , createobjectSet,, they have created a objectcontext ,readonly ObjectSet objestset & assigned like this

objectset = repositoryBOSql.Context.CreateObjectSet();

Context :- object of connection ,

I have to use Dbcontext to all over & have to also revert to everywhere, & also have to pass the entityObject (Dbset object) to all so that just replacement in RepositoryBo,baseBo I will able to convert All project from model first to code first Apporch .

edmx to EF Code First
You may use Entity framework power tool to generate Entity. It will generate entity and mapper class as well.
then you use DBContext instead of your previous code and change it accordingly.
