Ef core fromsqlraw: unable to call stored procedure

See more:

EF-Core

Hi.
I am trying to understand this method for a whole day long now now. I need to call a stored procedure, which does not return, or at least does not suppose to return anything. Just like a void method call. However, no matter what I am trying to do, it seems like such a pathetically childish simple task is not simply possible - is it correct? If it is - it is mind blowing.

What I have tried:

Simple SP:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[procedure_name]
AS
select 1
GO

Now I am trying to call this:

context.MyClassSet.FromSqlRaw("EXEC procedure_name;")

Which is of course

DbSet<MyClass> MyClassSet;

MyClass looks like this:

public class MyClass
{
    // public int id { get; set; }
}

The error in this case is: sequence contains no elements. If I uncomment id property - the error is: The required id bla bla is not present something.
The only thing I want, is just to call stored procedure and return nothing.
Can anyone help please?
