Fix staging Aspire CLI install command for polyglot apphost.ts support by Copilot · Pull Request #1496 · dotnet/aspire-samples

Copilot · 2026-03-03T15:47:19Z

The polyglot apphost.ts files require the staging Aspire CLI (native binary), not the NuGet-based tool. The install commands in POLYGLOT_NOTES.md used incorrect flags.

Changes

Fixed install command to match the canonical form: curl -sSL https://aspire.dev/install.sh | bash -s -- -q staging
Added polyglot docs link to https://aspiredev.netlify.app/app-host/polyglot-apphost/
Removed stale .aspire/settings.json accidentally committed from local testing

Still pending

Running aspire run for each apphost.ts to generate .modules/ and validate the gap analysis requires the staging CLI, which needs aspire.dev network access. The gap analysis in POLYGLOT_NOTES.md is spec-based and explicitly marked as unvalidated — actual API availability will differ once .modules/aspire.ts is generated.

# Required install (stable NuGet CLI does NOT detect apphost.ts):
curl -sSL https://aspire.dev/install.sh | bash -s -- -q staging

# Then for each sample:
cd samples/<sample>/AppHost
aspire add redis    # triggers SDK codegen
aspire run          # generates .modules/, starts app

Create TypeScript equivalents of C# AppHost.cs files using the Aspire polyglot apphost SDK for 14 samples.

Hey @copilot, while you did an okay job - I think you might need to adjust how you approached this problem slightly. When you create the TypeScript apphost.ts, you need to add integrations using the aspire add {package} command. This is the correct way to add packages with the polyglot approach, and should help resolve the staging packages correctly.

Address review feedback: each apphost.ts now includes setup comments listing which aspire add commands to run for integration packages. Previously commented-out code (marked as POLYGLOT GAP) is now active code that uses APIs available after running aspire add. Updated POLYGLOT_NOTES.md with per-sample setup instructions and revised feasibility matrix. Co-authored-by: IEvangelist <7679720+IEvangelist@users.noreply.github.com>

Updated in 781e1e0 and 8e2710f. Each apphost.ts now starts with setup comments listing the required aspire add commands (e.g., aspire add redis, aspire add javascript, aspire add orleans). Previously commented-out code that was marked as "POLYGLOT GAP" is now active code that uses the APIs made available after running the appropriate aspire add commands. The POLYGLOT_NOTES.md has been updated with per-sample setup instructions and a revised feasibility matrix — most samples now show as "Mostly" or "Fully" convertible.

…pphost.ts The stable Aspire CLI (13.1.2 from NuGet) does not include TypeScript polyglot apphost support. The native staging binary from aspire.dev is required to detect and run apphost.ts files. Updated POLYGLOT_NOTES.md to clearly document this, mark all feasibility ratings as expected rather than confirmed, add a validation checklist, and note the container runtime prerequisite.
