Creating classes in Efcore implements the partner class implementation of the entity class by implementing the Ientitytypeconfiguration<t> interface Fluentapi

1 Creating an Entity class:

  Public Partial classNewscategory:iaggregationroot { Publicnewscategory () {} PublicGuid Id {Get;Set; }  Public stringCategoryName {Get;Set; }  Public BOOLIsdel {Get;Set; }  Public stringCode {Get;Set; } }

2. Create a mapping partner class for an entity class

 Public class Newscategorymap:ientitytypeconfiguration<newscategory>    {        publicvoid Configure (entitytypebuilder<newscategory> builder)        {            Builder. ToTable ("newscategory");        }    }

3. Override the Onmodelcreating method in context to apply the partner class

  Public classNewsefcorecontext:dbcontext,inewscontext { PublicDbset<newscategory> Categories {Get;Set; } protected Override voidonconfiguring (Dbcontextoptionsbuilder optionsbuilder) {//write the connection string directly and build the database. Later configured in the configuration file and used hereOptionsbuilder.usesqlserver ("Server=localhost;database=wehope; User Id=sa; Password=0"); //Optionsbuilder.usesqlserver (appsetting.getappsetting ("Dealercontext"));        }        protected Override voidonmodelcreating (ModelBuilder ModelBuilder) {modelbuilder.applyconfiguration<NewsCategory> (NewNewscategorymap ()); Base.         Onmodelcreating (ModelBuilder); }    }

Complete.
