从此链接获取帮助在Core 2.0或EntityFramework 7中，不支持ef 6的早期版本中提供的SqlQuery功能.

In Core 2.0 or EntityFramework 7 does not support SqlQuery feature which was available in previous version of ef 6.

下面是在EntityFramework 7中执行sp的示例.

Below is the example how you can execute sp in EntityFramework 7.

 public List<UserDetails> GetUserDetailsUsingSP(int LoggedInID)
        {
            var loggedInUser = new SqlParameter("Id", LoggedInID);

            return WidServices
                .FromSql("EXECUTE WID_Services_GetAll  @Id ", loggedInUser)
                .FirstOrDefault();
        }

注意:在要在主db上下文类下添加DbSet的位置添加此方法，然后通过实例化dbContext调用此方法.

Note : Add this method where you are adding your DbSet under your main db context class and then call this method by instantiating your dbContext.
