public static MyPassEntities Create()
{
    SqlConnectionStringBuilder sqlConnection = new SqlConnectionStringBuilder()
    {
        DataSource = "192.168.1.1",
        InitialCatalog = "project",
        UserID = "user",
        Password = "pass"
    };
    EntityConnectionStringBuilder EFconnection = new EntityConnectionStringBuilder()
    {
        ProviderConnectionString = sqlConnection.ToString(),
        Provider = "System.Data.SqlClient",
        Metadata = @"res://*/DbModel.Model1.csdl|res://*/DbModel.Model1.ssdl|res://*/DbModel.Model1.msl"
    };

    return new MyPassEntities(EFconnection.ConnectionString);
}

using (DbModel.MyPassEntities myContext = DbModel.MyPassEntities.Create())
{
    _Result = myContext.Data.FirstOrDefault(x => x.ID == id);
}
