Release notes

Sourced from Aspire.Hosting.AppHost's releases.

13.5.3

What's New in Aspire 13.5.3

Patch release for Aspire 13.5 that fixes Dashboard Graph view crashes for resources with multi-path icons and restores missing public URLs for DevTunnel resources.

🐛 Fixes

• 📊 Dashboard Graph view could crash for Azure Blob resources — Resources such as those created with AddBlobs use icons containing multiple SVG paths, which caused an XML parsing exception and broke the dashboard circuit. The graph now combines multi-path icons correctly. Regression introduced in 13.5. Fixes #​19489. (#​19585, backport of #​19579, @​sebastienros)

• 🌐 DevTunnel public URLs were missing from the Dashboard and MCP snapshots — DevTunnel port resources could report Running and Healthy while showing no public URLs. Proxyless port allocation is now limited to compute and container resources, allowing DevTunnels to publish their actual public endpoints. Regression introduced in 13.5. Fixes #​19496. (#​19625, backport of #​19590, @​karolz-ms, @​danegsta)

🏷️ Housekeeping

• 🚀 Bumped branding to 13.5.3

13.5.2

What's New in Aspire 13.5.2

Patch release for Aspire 13.5 that removes an unused native helper binary from the Windows CLI archives so 13.5 servicing releases stay publishable to WinGet.

🐛 Fixes

• 🪟 Windows CLI archives shipped an unused ~4.9 MB hex1bpty.exe — The Windows CLI archives (aspire-cli-win-{x64,arm64}-*.zip) bundled Hex1b's out-of-process PTY host, which Aspire never executes (DCP owns every pseudo-terminal Aspire surfaces). Besides the wasted download, the extra unexplained executable stalled the WinGet publish, since every binary in the archive goes through executable and malware validation. A build-only MSBuild target now drops the file from the CLI publish output; Unix native assets are unaffected. Regression new in 13.5.

13.5.1

What's New in Aspire 13.5.1

Patch release for Aspire 13.5 fixing a TypeScript/Java polyglot AppHost compatibility regression when running the 13.5 SDK under an older (13.4.x) CLI, plus a DCP update and release-pipeline housekeeping.

🐛 Fixes

• 🍎 Polyglot AppHosts could crash on startup on macOS — On macOS, polyglot (TypeScript/Python/Java/Go/Rust) AppHosts could crash during startup due to an interaction between how DCP's Go runtime forks detached processes and how .NET Native AOT installs its signal handlers. Updated DCP (Developer Control Plane) to 0.25.13 to resolve the crash. ([#​19528]([release/13.5] [main] Update dependencies from microsoft/dcp aspire#19528))

• 🔗 Polyglot AppHosts on the 13.5 SDK crashed under an older CLI with MissingMethodException — A TypeScript or Java AppHost built with the 13.5 SDK failed to start when launched by an older (13.4.x) CLI, because the newer codegen called Aspire.TypeSystem members that don't exist in the CLI's older contract. Code generation now probes for these additive capabilities before using them, so older CLIs skip only the unsupported feature and startup succeeds. Regression introduced in 13.5 by #​19365. Fixes #​19503. ([#​19524]([release/13.5] Preserve TypeSystem compatibility with older CLIs aspire#19524), backport of #​19506, @​adamint)

🏷️ Housekeeping

• 📦 Updated DCP (Developer Control Plane) to 0.25.13 ([#​19528]([release/13.5] [main] Update dependencies from microsoft/dcp aspire#19528))

• 🔧 Restored WinGet publication using .NET 9 wingetcreate ([#​19509]([release/13.5] fix(release): Restore WinGet publication with .NET 9 wingetcreate aspire#19509))

• 🧹 Removed the pipeline-scoped Publish-Build-Assets group from the release pipeline ([#​19523]([release/13.5] Remove pipeline-scoped Publish-Build-Assets group aspire#19523), [#​19163](Remove Publish-Build-Assets variable group from release/13.5 aspire#19163))

• 🚀 Bumped branding to 13.5.1 ([#​19531](Increment patch version from 0 to 1 aspire#19531))

13.5.0

Aspire 13.5.0

Aspire 13.5 is a developer-experience release focused on a richer, more interactive AppHost, closer C# and TypeScript parity, sharper tooling, more flexible deployment modeling, and a broad set of runtime-stability improvements.

Highlights

• 💬 Richer AppHost interactions — The Interaction Service now works across C# and TypeScript AppHosts with stable prompts and dynamic inputs, file uploads, progress dialogs, notifications, and user-defined resource command arguments that surface as dashboard controls and CLI options.
• 🖥️ Interactive terminal sessions — The experimental WithTerminal() API lets resources host REPLs, shells, TUIs, and other interactive programs directly in the dashboard, with an opt-in aspire terminal CLI command for attaching from your shell.
• 🌐 TypeScript AppHost is generally available — Polyglot AppHosts no longer require the ASPIREATS001 experimental diagnostic and gain custom health checks, container file copying, HTTPS developer certificates, faster startup, and several reliability fixes that further close the gap with C#.
• 🛠️ CLI installation and reliability — The Aspire CLI is available through npm and Nix alongside Homebrew, WinGet, mise, and NuGet. New C# AppHosts enable the CLI bundle by default, while aspire stop --force, aspire update --migrate, aspire doctor, docs search, signal handling, and stale-socket cleanup all improve day-to-day workflows.
• 🎨 Refreshed dashboard — The dashboard adopts official Aspire branding and a new accessible design-token system, with timestamp and exact numeric telemetry filters, console-log text search, clearer reconnect and health-check experiences, and correct telemetry streaming while filters are active.
• 💻 Rebranded VS Code extension — The extension is now named Aspire and adds an in-editor dashboard, Bun and MAUI debugging, resource commands in the tree view, discovered AppHosts, improved parameter handling, and more efficient workspace discovery.
• ☸️ More expressive deployments — Kubernetes and AKS gain first-class persistent volumes, Azure Container Apps adds deterministic unique resource naming, Azure environments support delegated subnets, and Docker Compose can publish Blazor gateways and configure shared memory.
• ☁️ Expanded hosting integrations — Azure resources can be referenced across resource groups, subscriptions, and tenants; the new Aspire.Hosting.Dotnet package models .NET projects by path; Radius deployment arrives in preview; and Foundry Local, Redis modules, dev tunnels, Go debugging, and other integrations gain new capabilities.

⚠️ Breaking changes

Notable changes include hosting context ServiceProvider properties being renamed to Services, PublishAsConnectionString becoming obsolete in favor of AddConnectionString, removal of aspire ps --resources and --include-hidden in favor of aspire describe, earlier proxyless endpoint port allocation, deprecation of the GitHub Models integration, removal of the dashboard AI Assistant, and opt-in rather than automatic dashboard launch from the VS Code extension.

MAF Automated Review — Iteration 1

Result: Findings reported
Scope: full PR (1 commit(s)): b414722db52b
Model: gpt-5.6-sol-fast

Overview

The PR centrally updates Aspire.Hosting.AppHost for three sample AppHost projects, and central package management keeps the dependency selection explicit. The warning-as-error solution build provides a strong compatibility guard, but 13.5.3 introduces a default ASPIRE010 warning that this guard promotes to an error for the included ChatWithAgent AppHost. The package bump therefore cannot pass the required .NET build until the new CLI-bundle choice is configured explicitly.

Reviewed the supplied pull-request change set across correctness, security/reliability, architecture, and failure behavior.
1 verified finding remained after source verification (1 high) across 1 file. Details are attached to the affected lines below.

Affected areas: dotnet/Directory.Packages.props

[github-actions]

The 13.5.3 package now emits ASPIRE010 when AspireUseCliBundle is unset, because its props default that property to false. ChatWithAgent.AppHost is included in SK-dotnet.slnx, and CI builds every solution with --warnaserror, so this upgrade makes the required .NET build fail before tests run. Please explicitly enable AspireUseCliBundle for the AppHost projects, or suppress ASPIRE010 where retaining the legacy behavior is intentional.
