How to fix Can't use Server.MapPath in ASP.NET MVC

If you're encountering issues with Server.MapPath or the visual intellisense doesen't have quick result options, Here are some potential solutions:

Ensure you're using HttpContext.Current.Server.MapPath instead of just Server.MapPath. In ASP.NET MVC, HttpContext.Current provides access to the current HttpContext object, which contains information about the current HTTP request.

string path = System.Web.HttpContext.Current.Server.MapPath($"~/bin/reports");

In ASP.NET, you can use HostingEnvironment.MapPath method to map a virtual path to a physical path. This method is preferred in certain contexts, especially if you're working outside of the context of an HTTP request.

string path = System.Web.Hosting.HostingEnvironment.MapPath($"~/bin/reports");

And don't forget to add a reference to System.Web.dll
