PowerCoin -- A Powershell Wrapper for Bitcoin json-rpc

[jagallout]

Hello All,

I am a hobbyist .Net developer and had been trying (unsuccessfully) to use the "Bitnet" project (http://sourceforge.net/projects/bitnet/) for a while.  I finally got fed up and decided to start from scratch, below you will find the "first-pass"/"proof of concept" implementation of some of the "more commonly" used bitcoind rpc calls.  Most of the work is in the string formatting, and you will still have to handle the json string that gets returned, but its a start, and hopefully someone will find it useful.

It makes use of Invoke-WebRequest command available in Powershell 4.0

Any input would be appreciated!  Feel free to use/distribute to your hearts content, I simply ask that any improvements or extensions make their way back to this thread.

Enjoy:
copy the following text into a new file and save it as PowerCoin.ps1

##Title: PowerCoin
##Version: 0.01
##Date: 6/7/2014
##Author: jagallout
##Usage: It works best to dot source the .ps1 file (e.g. PS C:\[path to PowerCoin.ps1]> . .\PowerCoin.ps1 )
##This will prompt you for a username/password and for the Uri for the rpc server, then you can just call the methods by name (e.g. getinfo)
