Passing Custom Build Arguments to Dotnet Build When Debugging Docker Compose Project

[bt-Knodel]

I'd like to be able to pass a build arguments when debugging a docker compose project in visual studio to one of the dependent services.

In particular, we build a few projects with RuntimeIdentifier, and when running docker compose I'd like for this to be set explicitly to what the docker container runs on. Ideally, I could default it to windows (the current environment) and when debugging docker compose, set it explicitly to linux-x64.

Any ways to address this?

Anyone able to provide any advice here?

When a developer debugs the docker compose project, I'd like for my app to build to Linux. When they build and run the console app directly, I'd like for it to be windows. The goal is to transition to Linux after a short period rather than all at once.

The best way I can think of to do what you want would be to use Build Configurations for the different RuntimeIdentifiers. You can find an example for how to do that with compose projects here: ComposeConfigurationExample
