Annual (Timed) Subscription License (Only available in select geographic locations)
Licensed per developer on a yearly subscription basis. You can build and publish unlimited .NET applications using ComponentOne controls during your subscription period. You must renew your Annual Subscription License to continue to use the software.

Developer Licenses are perpetual and include a 1 year Support and Updates Subscription which provides 1 year of free upgrades, including bug fixes and new features. The perpetual license entitles you to build .NET applications using the ComponentOne controls. The applications you build can be distributed royalty-free.
After your support and updates subscription expires, you can renew to receive another year of updates. If you choose not to renew, you can continue using the last version of the controls you are eligible to use.
