Support Source Generators in Notebooks #1786

Open JasonBock opened 2 years ago

JasonBock commented 2 years ago

Is your feature request related to a problem? Please describe. It's not a problem, just something I'd like to see work in a notebook.

Describe the solution you'd like I noticed that if I reference a NuGet package in a notebook where that package contains source generators, the generators won't execute. Therefore, I can't use the package as intended. I'd like to be able to demo/document source generator packages using a notebook, so hopefully this will be supported in the future.

Note: @jonsequitur mentioned I should add this as an issue, so....here it is :)

Describe alternatives you've considered No alternatives.

Any update on this issue?

Also curious.

The compilation model for C# Script is different enough that source generators as currently designed won't work.

But at the same time, the use cases for source generation within a notebook might also be a little different as well. One example is generating classes from data in memory. The experimental #!linqify magic command (i.e. LINQ to CSV) offers one example.

The code for this is actually pretty simple and might offer some ideas for a different approach to source generation.
