In my TechEd presention I demoed writing messages into an Azure Storage Queue from a Netduino Plus. I have knocked up a couple of basic NetduinoPlus samples to show how this works. The code was inspired by these articles
Both versions have a dependency on a third party SHA implementation (I really didn’t want to implement that myself) of which there are several available for the .Net MF. I have used ones from inControl & ElzeKool successfully.
There are two versions, one which has a dependency on the .Net MF Common extensions for basic string manipulation fuinctionality and a low dependency version which uses only what is available in the .Net MF framework.
Code is available from here
