Hello! Bhuvanesh Sir.. Here $ is a string interpolation operation method that is new feature of C# 6. String interpolation syntax allows strings to directly replace the literal string indexes by holes with the expressions that correspond to the values. It is a advance form of string format(string.format) like string url=String.Format(Hello my url is {0} and path is {1}baseUrlpath); You can achivev same thing uisng interpolation operator in some simple steps like string url = $Hello My Url is {baseUrl} and path is {path}; That is more simpler way to format a string compare to previous method.........
