You want to integrate that with a library you wrote while learning F#. And you want to tie it all together with a WCF service in C#.
Yes, because a beginner programmer needs to do that....
Less useful but still useful are command shells. These provide file management mostly. I believe some of them may allow for sending and retrieving email messages. Also useful but less accessible and with a steeper learning curve are software with APIs and scripting. Examples would be Visual Basic for Applications in office software and groovy scripting for Freeplane. What else is out there?"
3D Studio 1.0 (DOS) was awesome at 640x480!!!!
Your good nature will bring you unbounded happiness.
