Polyglot debugging support

[tjwald]

As part of the 2025-2026 roadmap, there is a section on polyglot debugging.
@davidfowl mentioned that this is already supported in Aspire just not out of the box, and when I reached out to Jetbrains Rider they said that they are blocked.
Please discuss - we really want this polyglot debugging support as we are using dotnet, typescript, go and python.

Hi, folks! As I understand it, DCP only calls the IDE for dotnet projects. Support for other languages is implemented in the form of executables (as far as I know). And IDEs are not involved in this flow.

There's a limited, undocumented exception for this. See https://github.com/dotnet/aspire/blob/main/src/Aspire.Hosting/SupportsDebuggingAnnotation.cs

Naming and implementation details will be solidified soon. I will publish a PR with the proposal and tag you.

Thank you!

@rafaelldi @adamint Any update on this?

[adamint]

The IDE spec now includes support for python projects in aspire 13. It's up to the Jetbrains team to support now
