The title of that post i a bit “mysterious” but let me first start with all the best wishes for a New Year. Last year was amazing hard work with cutting edge project, I had to relax from heavy development a bit and do something else. That’s where Netduino comes into play. Netduino is an open source electronics platform using the .NET Micro Framework.The .NET Micro Framework is a very cool development platform which makes it possible to write high level, code and deploy it onto micro devices. Netduino itself is a amazing microcontroller, runs.net you can use all Visual Studio features including debugging. Project that I did is pretty simple, one temperature sensor (DS18S20) (OneWire) connected to Netduino reads current temperature value and sends to WCF REST service hosted on Windows Azure, service publishes that value to queue and another worker roles picks that and sends to CRM Online. Full architecture is visible on the image bellow.
That particular project is very simple but proves that Azure is very flexible, scalable, easy to work and very efficient platform for “distributed/connected systems”. You can easily imagine some “network” of micro devices connected to Azure sending , requesting and processing data, or even some devices “driven” via cloud from your phone. I’d say sky is the limit. What is even more interesting MS Dynamics CRM again proved XRM nature first of all I didn’t have to spend a lot of time to build presentation layer and data model and moreover my data model had nothing in common with customers and relationships with them. UI utilizes graphical capabilities i.e charts and all of that is out of the box. See result on screens bellow. Full source code of that solution is attached to that post. If you are interested in “wiring” and “electronics” let me know I can guide you how to build circuit etc ,but picture is worth a thousand words so please find attached screenshots and images.

Update 1
Full source code of the solutions is available here . I was using OneWire sensor Netduino currently OOB doesn’t support that yet (It will be soon) but, there is a experimental firmware and driver which works . You can find it at netduino forum.
Update 2
List of components : 1 mini breadboard , Nutduino plus , 1 resistor 4,7K , some wires , DS18S20 high-precision 1-Wire Digital Thermometer , 1 Windows Azure account , 1 MS Dynamics CRM Online account.
Update 3
Source code is a “R&D” version there are some parts that can be optimized i.e instead using “HttpWebRequest” I could use sockets etc.

). CRM SDK version from December 2010 contains sample app and I’m not going to reinvent a wheel. I’ll show what you need to configure in that app to receive messages from our CRM system. Presented example will be the simplest one as mentioned in previous post it is one way integration, so message comes from CRM Online via AppFabric Service Bus to our app . Let’s get hands dirty I attached ready to compile
