Why Entity Framework core does not support raw sql query?

I was using entity framework 6 in my asp.net application and using raw queries like following:

string studentName = ctx.Database.SqlQuery<string>(
         "Select studentname from Student where studentid=1").FirstOrDefault();

Now I am moving my application to asp.net core, but I could not found raw sql query without using DbSet type.

var students = context.Students
                  .FromSql("Select * from Students where Name = 'Bill'")
                  .ToList();

But this does not solve my solutions.

Is there any extension that developed to run sql queries?
