What's New

🏠 AppHost

4 improvements

Improvements

  1. ⚙️ Standardize resource service endpoint URL config name
    The resource service endpoint URL is now resolved using KnownConfigNames (ASPIRE_RESOURCE_SERVICE_ENDPOINT_URL) with a legacy fallback to DOTNET_RESOURCE_SERVICE_ENDPOINT_URL, improving consistency with Aspire naming conventions.
    Owner: @JamesNK
    Changes: #17385

  2. ⚓ Helm v4.2.0+ version validation for Kubernetes deploy
    Aspire now validates that Helm v4.2.0 or later is installed before running Kubernetes deployments. Previously, missing or outdated Helm produced cryptic low-level errors; users now see a clear, actionable message.
    Owner: @mitchdenny
    Changes: #17491
    Docs: microsoft/aspire.dev#1090
    📝 Documentation required

  3. 🌐 Blazor gateway Docker Compose publish support
    Adds Docker Compose publish support for the Blazor gateway and addresses various review feedback items including resource name attributes and improved OTLP warning placement.
    Owner: @davidfowl
    Changes: #17384
    📝 Documentation required
    🌍 Community contribution by @javiercn

  4. 🔌 Backchannel property compatibility improvements
    Preserves auxiliary backchannel backward compatibility while enabling rich JSON property values (numbers, booleans, arrays) for clients that advertise the new aux.v4 capability. The CLI now sends its client capabilities when using v2 resource snapshots.
    Owner: @adamint
    Changes: #17507

💻 CLI

1 new feature, 3 improvements, 2 bug fixes

New features

  1. 📦 Embedded Aspire skills bundle fallback
    The Aspire skills bundle is now embedded in the CLI as a reliable fallback. When GitHub release asset acquisition is unavailable, the CLI uses the embedded bundle and shows a non-fatal warning instead of failing the entire command.
    Owner: @IEvangelist
    Changes: #17537, #17547
    Docs: microsoft/aspire.dev#1137
    📝 Documentation required

Improvements

  1. 🔎 Updated --search option help text
    The --search option in aspire logs and telemetry commands now includes a link to aka.ms/aspire/cli-search and clarifies support for both full-text search and field filters.
    Owner: @JamesNK
    Changes: #17544
    Docs: microsoft/aspire.dev#948, microsoft/aspire.dev#1081

  2. 🔍 Enriched AppHost codegen TypeLoadException diagnostics
    When AppHost code generation fails due to a TypeLoadException (typically caused by a version mismatch between the CLI and the user project), the CLI now provides enriched diagnostic output to help identify the cause.
    Owner: @IEvangelist
    Changes: #17262

  3. 🎨 Improved aspire agent init install output
    The aspire agent init command now collects updated skill/location pairs and prints one compact summary instead of repeating a success line for every skill at every install target.
    Owner: @IEvangelist
    Changes: #17519

Bug fixes

  1. 💬 Friendly error for aspire do --list-steps without a step
    Running aspire do --list-steps without specifying a step now gives a clear validation error instead of launching the AppHost and crashing with an obscure exception.
    Owner: @mitchdenny
    Changes: #17535
    Docs: microsoft/aspire.dev#1091
    📝 Documentation required

  2. 🔒 Fix Aspire skills attestation verification
    Fixed a bug where aspire agent init failed to install the Aspire skills bundle because the attestation verifier used a stale SLSA build type URL. The verifier now accepts the current GitHub Actions build type URL.
    Owner: @IEvangelist
    Changes: #17521

🧩 Extensions

1 bug fix

Bug fixes

  1. 🛠️ Fix VS Code AppHost launch path resolution
    Fixed an issue in the VS Code extension where starting an Aspire debug session from a source file (e.g., Program.cs) would pass the source path to the CLI instead of the project file path, causing the session to fail.
    Owner: @davidfowl
    Changes: #17408

🔌 Integrations

1 bug fix

Bug fixes

  1. 🐛 Fix EF Hosting migration pipeline step handling
    Fixed issues in the Entity Framework hosting integration migration pipeline where migration steps were unconditionally added to the bundle-generate step. Improves reliability of EF migration orchestration in AppHost.
    Owner: @AndriySvyryd
    Changes: #16966
