v13.5.2: Aspire 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. ([#​19557](#​19557), backport of #​19554, @mitchdenny)

🏷️ Housekeeping

• 🚀 Bumped branding to 13.5.2

v13.5.1: Aspire 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](#​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](#​19524), backport of #​19506, @adamint)

🏷️ Housekeeping

• 📦 Updated DCP (Developer Control Plane) to 0.25.13 ([#​19528](#​19528))

• 🔧 Restored WinGet publication using .NET 9 wingetcreate ([#​19509](#​19509))

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

• 🚀 Bumped branding to 13.5.1 ([#​19531](#​19531))

v13.5.0: Aspire 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.

v13.4.6: Aspire 13.4.6

What's New in Aspire 13.4.6

Patch release for Aspire 13.4 fixing polyglot AppHost code generation binding when CLI and SDK versions diverge, resource service port collision in --isolated mode, and a MongoDB.Driver dependency update.

🐛 Fixes

• 🔗 Polyglot AppHost code generation silently failed when CLI and SDK versions diverged — Aspire.TypeSystem used a floating strong-name AssemblyVersion that changed with every build. When the installed Aspire CLI was built at a different version than the AppHost's SDK, the CLR couldn't satisfy the strong-name bind and every code generator (TypeScript, Python, Java, Go, Rust) was silently dropped, surfacing as No code generator found for language: <lang>. The AssemblyVersion is now frozen at a stable constant so any compatible CLI/SDK pair on 13.4 binds successfully. Relates to #​18110 and #​17910. (#​18160, @sebastienros)

• 🔌 Multiple AppHosts started with --isolated collided on the resource service port — Both instances tried to bind to the same fixed port from ASPIRE_RESOURCE_SERVICE_ENDPOINT_URL, causing an "address already in use" error on the second instance. DashboardServiceHost now binds to port 0 on loopback when RandomizePorts is true (set by --isolated), letting the OS assign a unique port per instance. (#​18341, @JamesNK)

• 🍃 MongoDB.Driver updated to 3.9.0 — Removes a wrongly pinned SharpCompress transitive dependency and uses the corrected Snappier transitive. Fixes #​17981. (#​18279, @Falco20019)

🏷️ Housekeeping

• 🚀 Bumped branding to 13.4.6 (#​18343)

v13.4.5: Aspire 13.4.5

What's New in Aspire 13.4.5

Patch release for Aspire 13.4 clearing a transitive MessagePack security advisory, tightening CLI validation for Playwright configuration, and adding coding-agent detection to CLI telemetry.

🐛 Fixes

• 🛡️ Bumped StreamJsonRpc to 2.25.29 to clear the MessagePack GHSA-hv8m-jj95-wg3x (CVE-2026-48109) NU1903 advisory — The transitive MessagePack 2.5.192 dependency pulled in via StreamJsonRpc 2.22.23 fell within the advisory's vulnerable LZ4 decompression range. Aspire does not use MessagePackFormatter or LZ4 — all StreamJsonRpc calls use SystemTextJsonFormatter over local Unix sockets — so the vulnerability was not reachable in practice. The bump clears the NU1903 warning for consumers of the Aspire.Hosting package. (#​18204, @mitchdenny)
• 🎭 playwrightCliVersion values that are not valid SemVer 2.0 now fail fast with a clear diagnostic — Previously an invalid override (range expression, dist-tag like latest, or a v-prefixed string) would surface as a generic npm resolution failure. The value is now validated with strict SemVer parsing at startup; an error naming the configuration key and the offending value is emitted immediately. (#​18205, @mitchdenny)
• 🤖 CLI telemetry now detects and reports the calling coding agent — When the Aspire CLI is invoked from inside a known coding agent environment (GitHub Copilot CLI, VS Code Copilot agent, etc.) the agent name is included in the main CLI telemetry event. GitHub Copilot CLI is specifically identified as copilot-cli. (#​18240, @damianedwards)

🏷️ Housekeeping

• 📄 Refreshed the @microsoft/aspire-cli npm package README to be TypeScript-only — updated examples to the current ts-starter template (apphost.mts / aspire.mjs), added a backing-services snippet showing aspire add for PostgreSQL and Redis, and documented aspire dashboard run as a standalone dashboard option. (#​18221, @adamint)
