Is there a way to query hstore columns using LINQ ?
I would expect something like this to work:

public class Product
{
   public int Id { get; set; }
   //This is correctly set as hstore in OnModelCreating
   public Dictionary<string, string> Tags { get; set; } 
}
ApplicationDbContext db = ...

var prods = db.Products.Where(p => p.Tags["Variant"].Equals("SD")).ToList();

However that WHERE statement is evaluated at client and I want it to be evaluated in db server.
I expect something like this to be generated
select * from "Products" where "Tags" -> 'Variant' = 'SD'

This works so everything is configured correctly.
var prods = db.Products.FromSql("select * from \"Products\" where \"Tags\" -> 'Variant' = 'SD'").ToList();
