Hello,
I have extensive experience in .Net (C#), working in the software development industry for more than five years i have worked on developing complex applications in almost all areas e.g. Desktop apps, web apps, web services, WPF, WCF, Web API etc.
The required application will be written in C#.Net, which will read email addresses from any given file, parse the email addresses at the same time and will create a new file and appent all the email address to the new file. PM for further discussion.
Thank You
