Answer 1

var objContext = ((IObjectContextAdapter)this.context).ObjectContext;

var objSet = objContext.CreateObjectSet();

var entityKey = objContext.CreateEntityKey(objSet.EntitySet.Name, entityToUpdate);

Object foundEntity;

var exits = objContext.TryGetObjectByKey(entityKey, out foundEntity);

if (exits && this.dbset.Local != null && this.dbset.Local.Contains(foundEntity) &&this.dbset.Local.Any())                    
{
  if (entityKey.EntityKeyValues != null && entityKey.EntityKeyValues.Any())                       
  {       
    DbEntityEntry entry = this.context.Entry(this.dbset.Find(entityKey.EntityKeyValues.FirstOrDefault().Value));
                        entry.CurrentValues.SetValues(entityToUpdate);
   }
}

this.context.SaveChanges();
