Of course, if you are not in a web application, no way you can use the HttpContext.Current !

you can check if System.Web.HttpContext.Current is null or not, it's available only in web pages or web services.

The follow up question then is how to return a relative path without Server.MapPath in C#.

Davide Piras Over a year ago

since the MapPath is relative to the current virtual directory or web site, does not make sense to use it in a non web application. if you simply want to change a relative path into an absolute path in any location of the file system, Server.MapPath is NOT what you need.

Another issue is that the free community version seems to only work in .NET Framework and not .NET Core sadly.
