A couple of months I got to go over to Seattle to the MVP Summit and surprising amongst the many meals out and occasional port's sniffed, I did actually check out some cool stuff. One of the most notable (for professional and general interest reasons) was the .NET Micro Framework.

Anyhoo, a slot came up in my schedule for some R&D work and we purchased the 'Tahoe Development Platform' from EmbeddedFusion.com for $299.99 - an absolute snip and at the time of writing the only one that actually for sale and by far the cheapest compared to other non-released platforms.

Installing the SDK (both MS's and Embedded Fusion) was fun with both installers crashing out, the EmbeddedFusion/Tahoe samples not working correctly and to be fair, some schoolboy C# mistakes (I'm still a 95% VB'er unfortunately) Anyhoo, here's a couple of gotcha's that might help you out if you're starting along this track...

  • Because I had installed VS2005 Service Pack 1, a lot of features mentioned are not available, namely debugging directly on the device and automatically deploying to the device. I have to manually switch the 'Transport' and 'Device' element, Deploy the application, reset the application on the Tahoe hardware. Not exactly seamless.
  • When adding image resources to your assembly, the IDE will automatically add the 'System.Drawing' namespace to your application. Unfortunately, when you come to run your .NET Micro application it will crap out with the message "Error: Assembly file "does not exist! Load failed". So if you add an image resource to your .NET Micro assembly you need to remove this. More details on this...
  • The SDK help is woefully inadequate compared with the .NET help. My favourite is the 'RotateBlt' function of the Bitmap class - the routine is now obsolete and not supported (and to be fair, doesn't seem to work) but doesn't provide any WPF alternatives, it mentions some namespaces that lead to dead ends...
  • There are no tutorials or blogs about messing with the .NET Micro Framework so those cries for help can echo somewhat ;-)
  • Coming from an web and windows background I kinda knew that the interaction with the application / screen / objects would be slightly different and its taking some time to adapt - especially, once you get past the 'Hello World' stage.

However, I'm pretty buoyant about what we can do with this - my concern is that its one thing developing on a dev platform like the Tahoe. It’s another thing procuring specific hardware to perform a specific tasks and then doing the easy bit of writing the code. I guess it would be nice if there was a website where you could dynamically build your hardware that could then be coded for...

Might be back with experiments...

I share your pain about the lack of blogs (or material in general) containing .NET Micro Framework related information.

I've recently started blogging about the topic on my blog, to try to share my experiences.

There isn't much of interest to you at present (by the looks of it you already know more about the framework than what I have blogged about so far). However I hope over time that the amount of material will grow, and it will become more interesting.

Thanks

Hi,

I to am searching for tutorials or documentation, which is quite skimpy. I am a .net developer and just began tinkering with electronics. I just did my first electronics project, How to shoot a paintbal gun with a laser, you can watch the video and tutorial on how it was made by clicking my name above.

Anyway, while searching for some info for next project, on books24x7.com I came across

Embedded Programming with the Microsoft .NET Micro Framework
by Donald Thompson and Rob S. Miles
Microsoft Press © 2007 (288 pages)
ISBN:9780735623651

I was excited to see that microsoft had the platform, and I have never heard of. Unfortunately, the book is aimed at the beginning .net programmer and doesnt really have real world examples. Another is problem is the book uses the Freescale i.MXS development kit which runs almost $500 USD. To that's just not feasible... If you are going to make a product or device that cost over $500 dollars then it should have more features than an Iphone, of PS3

Altough the Basic Stamp 2 controller allows you to program the microconctroller in a very VB like language (PBasic), It is a properietary technology. You can integrate other third party electronics, but you need to know you stuff. I am just a beginner in electronics.

I guess this field is still in its infancy, but it looks promising. I am trying to learn how to move forward...
