Solution 1

That's a message which appears when you are debugging your code and trying to examine the value of a variable, but the debugger has determined that retrieving the value would alter the state of your program.

Why do we get “The function evaluation requires all threads to run” | Microsoft Docs[^]

as the documentation activated debug and presents this error SELECT `Extent1`.`id_pets`, `Extent1`.`id_cliente`, `Extent1`.`nome`, `Extent1`.`Sexo`, `Extent1`.`especie`, `Extent1`.`raca`, `Extent1`.`idade`, `Extent1`.`descricao`, `Extent1`.`imagem` FROM `pets` AS `Extent1` INNER JOIN `clientes` AS `Extent2` ON `Extent1`.`id_pets` = `Extent2`.`id_cliente` WHERE `Extent2`.`id_cliente` = @p__linq__0

That's not an error; that's the SQL query it's going to execute.

From what I discovered it must be some query error because when the client id and pet id is the same in the pets table it returns the pet linked to the user, however when the pet id is different it doesn't work.

I found out it was just a mistake of mine to query the tables was comparing the values incorrectly.
int idcliente = new LoginController().Clientes(this);
var consultar = from pets in db.pets
join c in db.clientes on pets.id_cliente equals c.id_cliente
where c.id_cliente == idcliente
select pets;
return View(consultar.OrderBy(p => p.nome));
