Expected behavior

More info needed on why path is illegal. Error makes no sense in a project that otherwise compiles and runs.

Less Complier v 0.9.38
Upon opening any LESS file in the web project produces the above exception

When LESS file contains an import that has url("//file.less")
Where the path in the url can not be used to create a FileInfo object
an exception of type System.ArgumentException is thrown.
