Web Forms deprecation with Sitefinity CMS 14.1
DISCLAIMER: The Web Forms related documentation has been removed in version 14.1 of Sitefinity product documentation as obsolete. This is done in accordance with the deprecated Web Forms capabilities.
Deprecation scope
With the release of Sitefinity CMS 14.1 (March 2022), the support for the following capabilities in Sitefinity CMS frontend was discontinued:
- Web Forms widgets for front-end development
- Web Forms widget templates
- Hybrid page templates
- Responsive & Mobile design module (only used in relation to Web Forms)
On version 14.1 and higher, Web Forms capabilities for new projects are not available.
As an alternative option, the recommended frontend technology is ASP.NET Core.
Note that the deprecated capabilities are still included in later versions, such as 14.4 LTS, to facilitate the transition to ASP.NET Core.
Progress strongly advises against using Web Forms for production deployments in any version beyond 13.3 LTS, which remains the last officially supported version for Web Forms.
Customers who choose to deploy Web Forms based websites on versions beyond 13.3, do so at their own risk.
Web Forms capabilities are no longer eligible for support, feature development or bug fixes, including security updates. Any newly introduced or discovered issues, including critical bugs without workarounds, will not be addressed.
