Hi. CustomErrors mode=off means if you got any error then Asp.Net Uses it's default error page for all users. To know more about CustomErrors you can follow these articles, https://www.codeproject.com/Articles/2345/Custom-Errors-in-ASP-NET debug="true" means the compilation of pages will takes longer and it uses much more memory. So incase of production environment we should use debug="false". targetFramework="4.5" means the application belongs to the 4.5 .Net Framework. maxRequestLength="20480" executionTimeout="1600" means you can upload any file upto 20MB and executionTimeout is the time which will take to upload. If the Fileupload crossed these limits then it will show you error. If it Helps Mark as Answer. Thanks.
