Entity Framework is not interpreting my settings

I have a serious problem with the Entity Framework .

I have two tables: Módulos and Viaturas , both with the name of the primary key ID ( Database First ).

A vehicle can have a Module, but it can also be null, the association is not mandatory, however I have an FK in the Viaturas Table for Table Módulos , summarizing the Tables were created like this:

CREATE TABLE MODULOS
(
    ID NUMBER NOT NULL,

    CONSTRAINT PK_MODULOS PRIMARY KEY (ID)
);

CREATE TABLE VIATURAS
(
    ID NUMBER NOT NULL,

    PLACA VARCHAR2(10) NOT NULL,

    ID_MODULO NUMBER,

    CONSTRAINT PK_VIATURAS PRIMARY KEY (ID),

    CONSTRAINT FK_VIATURAS1 FOREIGN KEY (ID_MODULO) REFERENCES MODULOS (ID)
);

I tried to make the relationship in many ways, always without success in Entity.

Using only Data Annotations ...

Module Class:

[Table("MODULO")]
public partial class Modulo
{
    [Key]
    [Column("ID", TypeName = "NUMBER")]
    public long ModuloID { get; set; }

    public virtual Viatura Viatura { get; set; }
}

Car class:

[Table("VIATURA")]
public partial class Viatura
{
    [Key, ForeignKey("Modulo")]
    [Column("ID", TypeName = "NUMBER")]
    public long ViaturaID { get; set; }

    [Column("PLACA", TypeName = "VARCHAR2")]
    public string Placa { get; set; }

    [Column("ID_MODULO", TypeName = "NUMBER")]
    public long? ModuloID { get; set; }

    public virtual Modulo Modulo { get; set; }
}

When I run the query, Entity does not perform the comparison

VIATURA.ID_MODULO = MODULO.ID

Instead, it performs:

VIATURA.ID = MODULO.ID

FROM "VIATURA" "Extent1"
INNER JOIN "MODULO" "Extent2" ON "Extent1"."ID" = "Extent2"."ID"

Using Fluent API only:

Module Config:

HasKey(t => t.ModuloID);

Property(b => b.ModuloID).HasColumnName("ID");

Car Settings:

HasKey(c => c.ViaturaID);

Property(p => p.ViaturaID).HasColumnName("ID");

HasOptional(t => t.Modulo);

When I run the query, Entity also performs the comparison:

VIATURA.ID = MODULO.ID

Forcing the ID_MODULO column for the relationship in the Fluent API:

Car Settings:

HasKey(c => c.ViaturaID);

Property(p => p.ViaturaID).HasColumnName("ID");

HasRequired(h => h.Modulo).WithOptional().Map(m => m.MapKey("ID_MODULO"));

Module Config:

HasKey(t => t.ModuloID);

Property(b => b.ModuloID).HasColumnName("ID");

In this scenario, the relationship worked, but then Entity crashed, it now thinks that the column ID of the VIATURA table is called ViaturaID, and I said that the column name is ID.

  

{"ORA-00904: \" Extent2 \ ". \" Vehicle_ViaturaID \ ": identifier   invalid "}

I'm using the most current version of Entity (6.2.0) in Dotnet Framework 4.5.

Thank you in advance.
