Answer 1

EF Core documentation: Querying from Raw SQL Include an entity type in your EF model that matches the stored procedure output columns.

Answer 2

EF Core provides the following methods to execute a stored procedure:

1. Using DbSet<TEntity>.FromSql()

   Suppose there have a GetStudents stored procedure. You can execute SP using FromSql method in EF Core in the same way as above, as shown below.

    var context = new SchoolContext(); var students = context.Students.FromSql("GetStudents 'Bill'").ToList();

2. Using DbContext.Database.ExecuteSqlCommand()

   Supposer this have a CreateStudents stored procedure to insert students. Then, you could use the following code to call the SP.

    var context = new SchoolContext(); context.Database.ExecuteSqlCommand("CreateStudents @p0, @p1", parameters: new[] { "Bill", "Gates" });

More detail information, please check the article: Working with Stored Procedure in Entity Framework Core . Besides, you could also use the Raw SQL Queries to execute the stored procedure.
