# DataBus Binary Serializer


This DataBus serializer uses **`BinaryFormatter`** to serialize and deserialize DataBus properties.

<!-- snippet: BinaryDataBusUsage -->

```cs
endpointConfiguration.UseDataBus<FileShareDataBus, BinaryFormatterDataBusSerializer>();
```

> [!CAUTION]
> **`BinaryFormatter` is unsafe and deprecated.**  
> It cannot be secured and must not be used for processing data.  
> Stop using it as soon as possible, even if the data appears trustworthy.  
>
> Use a [safer serializer](/nservicebus/messaging/claimcheck/index.md#serialization) instead.  
> For guidance, see the upgrade notes:  
> **[Migration from BinaryFormatter](/nservicebus/upgrades/7to8/databus.md#migration-from-binaryformatter).**
