The name Savechanges() does not exist in the current context

Question

Hello Experts,

 

I am migrating my code from EF to EF Core.

We do have an Igenericreposirory.

And this Igenericreposirory is inheriting by Genericreposirory.

 

IGenericreposirory

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Linq.Expressions;

using System.Threading.Tasks;

namespace DataLayer.Repositories.Base

{

public interface IGenericRepository where T : class

{

T Add(T entity);

}

}

GenericRepository:

public class GeneralRepository : IGenericRepository

where T : class, IEntity, new()

{

protected readonly DbContext DbContext;

internal DbSet DbSet;

public GeneralRepository(DbContext dbContext)

{

if (dbContext == null)

throw new ArgumentNullException("dbContext");

this.DbContext = dbContext;

this.DbSet = this.DbContext.Set();

}

public virtual T Add(T entity)

{

#region Argument Validation

if (entity == null)

{

throw new ArgumentNullException("entity");

}

#endregion

var obj = DbSet.Add(entity);

SaveChanges();

return obj;

}

}

Here I am getting 2 errors while working with EF core

1 at return obj as "Cannot convert from 'Microsoft.EntityFrameworkCore.ChangeTracking.EntityEntry' to 'T'"

2 at Savechange() as "the name savechanges()" does not exists in the current context.

As far as i know , EF core supports all methods to fetch , Insert, ADD
