C# command line caller

Hi,

I would like to ask some information about a C# command line caller. Calls can be made from this command line caller and there is no need for a graphical user interface to run the program.

I think it looks promising. Please share your opinion about it because maybe I will purchase it.

It can be found here:

Thanks.
