    v13.4.6

    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 th...

    .NET Aspire — Aspire 13.4.5

    v13.4.5

    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.

    .NET Aspire — Aspire 13.4.4

    v13.4.4-release

    What's New in Aspire 13.4.4 Patch release for Aspire 13.4 with improved DCP connection reliability during request execution and consistent ExcludeFromMcp() filtering across all CLI MCP tools. 🐛 Fixes 🔌 DCP requests could fail permanently when the connection dropped mid-request — If the underlying DCP channel closed while a request was in flight, the error was surfaced directly instead of being retried. Reconnection is now attempted as part of the DCP request retry path so transient disc...

    .NET Aspire — Aspire 13.4.3

    v13.4.3

    What's New in Aspire 13.4.3 Patch release for Aspire 13.4 with a fix for persistent container endpoint allocation regressions introduced in 13.4. 🐛 Fixes - 🔌 Persistent container endpoints had incorrect default behavior — Persistent containers were defaulting to proxyless endpoint behavior instead of the proxied behavior used by normal containers. This caused integrations that depend on endpoint allocation before resource startup (such as the KeyVault emulator) to fail. Persistent containe...

    .NET Aspire — Aspire 13.4.2

    v13.4.2

    What's New in Aspire 13.4.2 Patch release for Aspire 13.4 with a fix for Redis persistent container deadlock on startup when using TLS. 🐛 Fixes - 🔴 Redis with WithLifetime(ContainerLifetime.Persistent) could deadlock on startup — Redis TLS startup arguments used the public/allocated host ports instead of the internal target ports. When the public port differed from the target port (or was not yet allocated) the container would listen on an unexpected port and become unreachable. The TLS an...

    .NET Aspire — Aspire 13.4.1

    v13.4.1

    What's New in Aspire 13.4.1 Patch release for Aspire 13.4 with fixes for explicit-start resource lifecycle callbacks, Redis persistent container startup, proxyless endpoint allocation, and a duplicated profiles block in the empty C AppHost template. 🐛 Fixes - ⏱️ Explicit-start resources triggered lifecycle callbacks too early — Session-scoped resources marked with WithExplicitStart() were having their execution configuration callbacks (environment variables, arguments, certificates) evaluat...

    .NET Aspire — Aspire 13.3.5

    v13.3.5

    What's New in Aspire 13.3.5 Patch release for Aspire 13.3 with fixes for the Azure provisioning location prompt and an Aspire CLI named-pipe timeout on Linux with .NET SDK 10.0.300. 🐛 Fixes - 📍 Azure provisioning location prompt not populated — Selecting an existing resource group during aspire publish now correctly populates dependent server-controlled fields (such as Location). Previously, server-provided values for disabled inputs were discarded, leaving those fields blank. (17278, back...

    .NET Aspire — Aspire 13.3.4

    v13.3.4

    What's New in Aspire 13.3.4 Patch release for Aspire 13.3 with a fix for the Aspire skill description exceeding agent host limits. 🐛 Fixes - 📝 Aspire skill description too long for agent hosts — The SKILL.md generated by aspire agent init included a frontmatter description that exceeded the 1024-character limit enforced by agent hosts such as Codex and Copilot CLI, causing the Aspire skill to fail to load. The bundled skill description has been shortened to stay within the limit. (17183, b...

    .NET Aspire — Aspire 13.3.3

    v13.3.3

    What's New in Aspire 13.3.3 Patch release for Aspire 13.3 with fixes for debug log level leaking into user resources, Keycloak HTTPS endpoint token invalidation, and endpoint materialization in HostResourceWithEndpoints. 🐛 Fixes - 🔇 Debug log level leaking into user resources — Logging__LogLevel__Default=Debug set by the app host was being inherited by all user resources, silently changing their logging verbosity. The app host now uses ASPIRE_APPHOST_LOGLEVEL instead, which is scoped to As...
