.NET for Apache Spark hits v1.0

About two years ago, we heard an increasing demand from the .NET community for an easier way to build big data applications with .NET, outside of needing to learn Scala or Python. Thus, in a collaboration between Azure Data and .NET teams, we started the .NET for Apache® Spark™ open source project.

Today, we are happy to announce the release of version 1.0 of .NET for Apache Spark, an open source package that brings high performance APIs for using Apache Spark from C# and F#. Indeed, it is the same technology that powers the .NET experience for Apache Spark inside Azure Synapse Analytics.


At a high-level, .NET for Apache Spark offers users the ability to:

  • Write Spark applications in C# or F# targeting .NET Core 2.1+.
  • Reuse existing C#/F# libraries and use the power of Apache Spark to parallelize them.
  • Leverage the high-quality Visual Studio or Visual Studio Code IDEs for building Spark apps.

The new .NET for Apache Spark v1.0 brings in additional capabilities to an already rich library:

We are extremely grateful to everyone who contributed towards reaching this important milestone. For more about the history of the project, key contributors, and its use in production pipelines, read the full announcement.
