Hello @Eric Huang (M365) ,

Thanks for the question and using MS Q&A platform.

Currently, the only way you can use a .dll file in Synapse notebooks is by packaging it into a NuGet and installing it in the notebook.

We don’t support workspace packages for .NET. You can load Nuget packages via session management: Use .NET for Apache Spark - Azure Synapse Analytics | Microsoft Learn

Note: If your .dll files are not a part of a publicly available NuGet package, and you need to use a private NuGet, please let me know and we can sync up on the steps needed to do that.

Hope this will help. Please let us know if any further queries.
