Halting notebook execution when cells returns an error or throws unhandled exception

[andrerav]

Hi!

I'm really loving .NET Interactive and I'm currently using it to set up some complex one-shot data migration pipelines that mixes C#, powershell and SQL.

I was wondering if there is a way to completely halt further notebook execution if a cell returns an error (i.e throws exception or a program returns an error code)? I've been looking through the docs but I can't seem to find a way to do this.

Best regards,
Andreas

We'll look into it.

Are you using the VS Code extension? Also, are you interested in automating the execution of this kind of notebook from the command line?

Great, thank you, it would be a very practical feature :)

Are you using the VS Code extension?

Yes, I am using v1.0.3504060 (preview)

Also, are you interested in automating the execution of this kind of notebook from the command line?

Yes! For example, it would be very nice to run this notebook in a continuous integration pipeline. If this hypothetically was possible today, then I would definitely set up a pipeline in our dev environment to run at least a few notebooks after merging PR's.

You might find the automation features in dotnet-repl interesting. It uses .NET Interactive and can run the same polyglot notebooks. We're using this to prototype potential automation features for the kernel.
