What is the aspnet_client folder? Can aspnet_client be deleted?

Under the root directory of the WEB site, most webmasters will find a folder named aspnet_client, which contains javascript integrating ASP. NET's "SmartNavigation" function. If SmartNavigation is enabled, web designers can maintain the position of the scroll bar and element focus between pages and other content.

The aspnet_client directory is the virtual root Web application directory, which is created on your computer when you install. NET Framework SDK or Visual Studio. NET. This file does not occupy user space. Please do not delete this folder when using the website space.

For example, the script files that come with ASP. NET are located in the following locations.

D: \ home \ ftp Username/wwwroot/aspnet_client/system_web/<version No.>/File
　
If you have installed Multiple SDK versions, you will see multiple subdirectories under aspnet_client/system_web. Because the control library is associated with a specific version of the script file, the deployment mode allows different versions of the control library to run in parallel.
