C# convert sql query into EF dbcontext linq to entities query

I have an sql server database and I use EF 6.0 to access it in my app.

I have the following SQL Query I need to convert to dbcontext linq to entities query and have some damn hard time figure it out.

This is the query:

select 
PA.Number, 
PA.Name,  
PR.* 
from MYDBNAME.dbo.Product PR 
join MYDBNAME.dbo.Order OD on PR.Id = OD.Id 
join MYDBNAME.dbo.Payment PA on OD.Id = PA.Id 
where PR.Year = 2017
and PR.StatusId = (select CD.Id from Code CD where CodeId = (select ST.Id 
from Status ST where ST.Value = 'Done')
and CD.State = 'Completed') 
and PA.Created = '2018-12-10' 
and PR.Amount <= 500


class Product
{
public string Id { get; set; }
public string Name { get; set; }
public decimal Amount { get; set; }
public string StatusId { get; set; }
public int Year {get; set;}
} 


class Order
{
public string Id { get; set; }

} 

class Payment
{
public string Id { get; set; }
public DateTime Created { get; set; }
public decimal Amount { get; set; }
public string Number { get; set; }
public string Name { get; set; }
} 

class Status
{
  public string Id { get; set; }
public string Value { get; set; }
} 

class Code
{
public string Id { get; set; }
public string CodeId { get; set; }
public string State { get; set; }
} 

As State and Code classes are not related with the rest, I guess that subquery should be run separately and then issue another dbcontext query for the main query
