ERROR_DEV_SIDELOAD_LIMIT_EXCEEDED
Development package registrations exceed the device allowance
ERROR_DEV_SIDELOAD_LIMIT_EXCEEDED applies to development or sideloaded package registrations rather than normal Store servicing. The device tracks such packages and refuses another development deployment when its configured allowance is exhausted.
Enumerate packages installed in development mode and remove obsolete test registrations from the device. Check automated test and CI deployment workflows that create new identities instead of updating or cleaning old builds. Do not delete package directories manually; unregister packages so deployment metadata and application data are handled correctly. Production packages should use a supported distribution identity rather than consuming development slots.
What to inspect
- List development-mode packages and their package family names.
- Clean stale test deployments in build automation.
- Use stable identities when repeatedly updating the same test app.
