The thing goes beyond that, the problem is that it always returns this error by instantiating this class:
namespace AlmoxarifadoUpas
{
class ConsultaMaterialEntradaSaida
{
private IEnumerable<MaterialA> materiais = new List<MaterialA>();
private void adicionarMaterialAutoComplete()
{
using (Entities db = new Entities())
{
db.Configuration.ProxyCreationEnabled = false;
var mate = from material in db.MaterialA
select material;
materiais = mate.ToList();
}
}
public IEnumerable<MaterialA> listaAutoComplete
{
get
{
adicionarMaterialAutoComplete();
return materiais;
}
}
}
}
Error:
The name "Query" does not exist in the namespace "clr-namespace:"
I thought it was strange because this class is inside the namespace. In this case I went to test with another class, for example this DAO class (does not have the content of the methods because I did not find it necessary, and I wanted to simplify):
namespace AlmoxarifadoUpas
{
class MaterialDAO : IMateriais
{
public void InserirMaterial(MaterialA material)
public List<MaterialA> Listar()
public bool VerificarSeCodigoExiste(string codigoMaterial)
public void RemoverMaterial(MaterialA material)
public void EditarMaterial(int id, string codigo, string nome, string unidade)
public void EntradaDeMateriais(HistoricoMovimentacao historico)
public void SaidaDeMateriais(HistoricoMovimentacao historico)
}
}
I don’t know about you, but I didn’t find the difference, and just when I put this class up it doesn’t make the mistake, does anyone know what it might be? Follow below as I am instantiating in the shaman

Already tried to close and open Visualstudio, clean the project and then rebuild?

@Igorventurelli Well, by miracle it worked when I did this, I think it’s on account of I’m using a this search textbox plugin. But it finally worked !
