I am using VS 2015. I am creating a a web form application. I've 4 Master Pages for different user roles. Everything was working fine. But when i move master pages to new folder then i got error of page not found then i edit my .csproj file in notepad and set the correct path for every master page file. Then project run successfully. But after login I got that error. **
dashboard.aspx is not allowed here because it does not extend class 'System.Web.UI.MasterPage'.
In that picture Inherits="E_Challan.CTO.CTOAdmin" represents that E_Challan is my project. CTO is folder and CTOAdmin is my master page which is located in CTO folder. So where i am doing mistake?
