[CommunityToolkit.Aspire.Hosting.Bun] Doesn't work with Workspaces

[kieronlanning]

Describe the bug

When using workspaces (bun), there is no bun.lock/ bun.lockb file in the bun project folder as they're managed from the root.

This results in Unhandled exception. System.InvalidOperationException: No bun.lock or bun.lockb file found .

An example project structure would look like this:

(root)
|- package.json
|- src
   |- web
      |- package.json

The package.json in the src/web folder would reference the 'workspace' like so:

{
    "name": "root-project",
    "type": "module",
    "private": true,
    "devDependencies": {
        "@commitlint/config-conventional": "^19.8.0",
        "@types/bun": "latest",
        "commit-and-tag-version": "^12.5.0",
        "commitlint": "^19.8.0",
        "editorconfig-checker": "^6.0.1",
        "husky": "^9.1.7"
    },
    "peerDependencies": {
        "typescript": "^5.8.2"
    },
    "scripts": {
        "release": "commit-and-tag-version"
    },
    "commitlint": {
        "extends": [
            "@commitlint/config-conventional"
        ]
    },
    "workspaces": [
        "src/web"
    ],
    "trustedDependencies": [
        "@parcel/watcher"
    ]
}

Regression

No response

Steps to reproduce

1. Create a package.json in a root folder
2. Create another in a 'workspace'
3. Reference the workspace from the root
4. Create an Aspire project, and reference the bun project in the workspace.

Expected behavior

Runs the project, regardless of the existence of the bun lock file.

No, just wanted to report this

I didn't realise that bun also would fallback to a package.json. I assume that it makes the most sense for it to only fail if it doesn't find the bun lock files or a package.json right?

[kieronlanning]

That should be enough...

There's a preview build of the Bun integration available (see https://github.com/CommunityToolkit/Aspire?tab=readme-ov-file#-installation for info on using PR builds) - let me know if that works as expected for you
