I am new to ASP.CORE and I want to Convert this statement from T-SQL using the CORE context

SQL

SELECT ID, SchemeCode, Name 
FROM   Scheme SM                
WHERE 
    SM.ParentID = 1             
AND sm.[ID] 
          IN (SELECT dd.[Scheme_id]
               FROM  dbo.[Employer_Detail] dd 
               INNER JOIN dbo.[Employer] er 
               ON dd.Employer_id = er.Employer_id
               WHERE er.Employer_Parent_id = 123

What I have tried:

I haven't tried anything as I am new to Core and don't know where to start.

Start here: Introduction to ASP.NET Core | Microsoft Docs[^]
Then start working your way through some tutorials e.g. Get started with ASP.NET Core MVC | Microsoft Docs[^]
Other tutorials are available on line[^]

It sounds as if you are some way off from needing that SQL embedded in any code.

Don't you think that I have been through the tutorials before I came here to ask this?

var npSchemes = from scheme in _context.Schemes
               join ded in _context.DeductionCodes on scheme.Id 
               equals ded.SchemeId
               join er in _context.Employers on ded.EmployerId 
               equals er.Id
               where scheme.ParentId == parentId 
               && er.ParentId == employerId
               select new {scheme.Id, scheme.Code, scheme.Name};
               var result = npSchemes.GroupBy(sm => sm.Id).Select(grp =>
               grp.First()).ToList();
