 # Read input in any format using .NET custom deserializers (Preview)

+> Custom .net deserializer for Azure Stream Analytics will be retired on 30th September 2024. After that date, it won't be possible to use the feature. Please transition to a [JSON, AVRO, or CSV built-in deserializer](./stream-analytics-parsing-json.md) by that date.

 .NET custom deserializers allow your Azure Stream Analytics job to read data from formats outside of the three [built-in data formats](stream-analytics-parsing-json.md). This article explains the serialization format and the interfaces that define .NET custom deserializers for Azure Stream Analytics cloud and edge jobs. There are also example deserializers for Protocol Buffer and CSV format.

 # Custom .NET deserializers for Azure Stream Analytics in Visual Studio (Preview)

 Azure Stream Analytics has [built-in support for three data formats](stream-analytics-parsing-json.md): JSON, CSV, and Avro. With custom .NET deserializers, you can read data from other formats such as [Protocol Buffer](https://developers.google.com/protocol-buffers/), [Bond](https://github.com/Microsoft/bond) and other user defined formats for both cloud and edge jobs.
 
 This tutorial demonstrates how to create a custom .NET deserializer for an Azure Stream Analytics cloud job using Visual Studio. To learn how to create .NET deserializers in Visual Studio Code, see [Create .NET deserializers for Azure Stream Analytics jobs in Visual Studio Code](visual-studio-code-custom-deserializer.md).
