We have a Sitecore 7.2 built using webforms; we're planning to upgrade it to version 9, just wondering if Sitecore 9 supports aspnet webforms?
Will the sublayouts work after the upgrade?
Thanks in advance.
Yes you can still use ASP.NET Web Forms even XSLT still work on Sitecore 9 also the WFFM module is still available for Sitecore 9.0 but not for Sitecore 9.1 and higher.. so if you use any module check if this is also available. Also keep in mind the new things in Sitecore 9, like Dynamic Placeholders and Sitecore Forms are MVC only.
