Note [en-us]:

• Use the [FipeVehicleTypesEnum] enumerator to say what type of vehicle you want to download for.
• Types of vehicles contained in the enumerator [FipeVehicleTypesEnum] (Car = 1, Motorcycle = 2, TruckAndMicroBus = 3)
• If the (referenceId == 0), the most current reference will be used, that is, the most current data from the fipe table will be downloaded.
• Warning: Do not call more than one FIPE library download service method in parallel, as the Proxy FIPE will block your IP for a certain time (5-10 minutes maybe).
• If you want to create the tables in the relational database [MSSQL / SqlServer], there are SQL scripts in the directory=[../Vasconcellos.FipeTable.Database/Tables/].
• If you to view [Vehicle.Year = 32000], it means that this vehicle is a Zero KM vehicle (New).
• The slowing in the download is caused that of the proxy of the [FIPE WebAPI] that performs momentary blocks.
• To avoid making requests while the proxy is locked, the service will pause the task for a few minutes and after will perform normal.
• The truck download is the fastest among them.
• Downloading the three types of vehicles together [Car, Motorcycle, Truck/MicroBus] takes between 2 or 4 hours

Observações [pt-br]:

• Use o enumerador [FipeVehicleTypesEnum] para dizer qual o tipo de veículo você deseja realizar o downlad.
• Tipos de veículos contidos no enumerador [FipeVehicleTypesEnum] (Carro = 1, Motocicleta = 2, Caminhão e Micro-Ônibus = 3)
• Se o (referenceId == 0), a referência mais atual será usada, ou seja, os dados mais atuais da tabela fipe serão baixados.
• Aviso: não chame mais de um método de serviço de download da biblioteca FIPE em paralelo, pois o Proxy da FIPE bloqueará o seu IP por um determinado tempo (talvez de 5 a 10 minutos).
• Se você deseja criar as tabelas no banco de dados relacional [MSSQL / SqlServer], existem scripts SQL no diretório = [../Vasconcellos.FipeTable.Database/Tables/].
• Se você visualizar [Vehicle.Year = 32000], quer dizer que este veículo, é um veículo Zero KM (Novo).
• O lentidão no download é causado pelo proxy da [FIPE WebAPI], a qual executa bloqueios momentâneos.
• Para evitar de fazer solicitações enquanto o proxy estiver bloqueado, o serviço pausará a tarefa por alguns minutos e depois será executado normalmente.
• O download do caminhão é o mais rápido entre eles.
• O download dos três tipos de veículos juntos [Carro, Motocicleta, Caminhão / MicroBus] leva entre 2 ou 4 horas
