Config Settings Table

Logical key	Stored in aspire.config.json as	Description
appHost.path	appHost.path	Project-scoped path to the default AppHost entry point. This setting must be configured in the local aspire.config.json file.
channel	channel	Default Aspire channel used by channel-aware commands such as aspire new, aspire init, and aspire update.
features.defaultWatchEnabled	features.defaultWatchEnabled	Enable or disable watch mode by default when running Aspire applications for automatic restarts on file changes.
features.experimentalPolyglot:go	features.experimentalPolyglot:go	Enable or disable experimental Go language support for polyglot Aspire applications.
features.experimentalPolyglot:java	features.experimentalPolyglot:java	Enable or disable experimental Java language support for polyglot Aspire applications.
features.experimentalPolyglot:python	features.experimentalPolyglot:python	Enable or disable experimental Python language support for polyglot Aspire applications.
features.experimentalPolyglot:rust	features.experimentalPolyglot:rust	Enable or disable experimental Rust language support for polyglot Aspire applications.
features.polyglotIntegrationFilterEnabled	features.polyglotIntegrationFilterEnabled	Enable or disable filtering aspire add, aspire integration list, and aspire integration search results to only integrations compatible with a non-C# (polyglot) AppHost. Disabled by default because remote NuGet feeds don’t reliably answer the tags:polyglot query used to build the compatibility allow-list.
features.showAllTemplates	features.showAllTemplates	Show all available templates, including experimental ones, in aspire new and aspire init.
features.showDeprecatedPackages	features.showDeprecatedPackages	Show or hide deprecated packages in aspire add search results.
features.updateNotificationsEnabled	features.updateNotificationsEnabled	Enable or disable Aspire CLI update notifications.
overrideStagingFeed	overrideStagingFeed	Escape hatch that always allows the staging channel to be resolved, regardless of the running CLI’s build identity. Set this to the staging feed URL you want channel-aware commands (aspire new, aspire init, aspire update) to use, for example: aspire config set -g overrideStagingFeed <feed-url>. Without this setting, --channel staging only resolves on stable or staging Aspire CLI builds — daily, local, and per-PR builds refuse it and report the recovery options.
