Obviously it's early days, I do not know whether this is information that is in the public domain or not yet, but...
I have trawled through some of this site - http://www.windowsphone7series.com/ but I can't seem to find the answer.
Specifically will I be able to write an app on the phone that updates the cloud with the phones current GPS position in the background even when other apps are running in the foreground.
According to ZDNet's post yesterday, Windows Mobile 7 will support multitasking for things like having music playing while using an application, but as far as 3rd party it will most likely not be supported. Things like notifications however will be there, as to help with multitasking.
I hate to relieve myself on your bonfire Christopher but might I suggest that a background GPS process, might not be a good idea. You'd really run down the users battery performance, perhaps if you shared a little more about your idea we could suggest an alternative architecture that didn't require a constant gps post.

Maybe I have't looked hard enough, but I spent yesterday googling for a bit and found no relevant projects on hacking the DJI Phantom Drone in order to create new coordinating apps. This is besides the app for coordination DJI currently uses for their drone. I'm trying to see if there's a way to communicate with the Drone with a specific protocol in order to accept a set of procedures.
Any help would be awesome,
Thanks.
Great News for you and all us Droneys! DJI has launched their SDK since you asked this question. They released it last November and you can now apply for a license and write your own apps for the Phantom2 Vision+ using their SDK.
Check it out at https://developer.dji.com/
I am already building a project using the SDK - you can follow my progress on my blog / product site. I will also try to update it with good DJI related development links and tips.
This post is old but I think it is good to leave a foot print for others :)
There is this new company called NVdrones, which created a peace of hardware that you can attach to any drone (you need physical access to the flight controller), and once you do that you can use their SDK (Arduino, Java, Android and Javascript) to write your app without the need of hacking, soldering or anything else. It is just plug and play.
Another benefit is that you are not locked with a specific drone (DJI SDK or 3DRobotics SDK), you can use the board on anything you want. Which gives lots of flexibility.
The developer site is http://developers.NVdrones.com
Hope this helps.
This is a great topic!
You could check how to hack your copter here: https://github.com/flyver/Flyver-SDK/wiki/-2.2--How-To:-Flyver-Hack-a-Copter
By opening the drone, taking out the original controller, soldering a few wires and sticking an Android phone to it, you will have the ability to program your Phantom in a modern manner with an open source SDK and application based development. This means that you could add computer vision to it, automation or additional hardware. You could also use smartphones, web and other interactive devices for remote controlling the copter instead of using the standard remote controls.
The Phantom, however, is offcenter balanced due to the fact that most people use gimbal with it. Without the gimbal is a lot less stable from my experiments so you will have to put some extra work in center balancing it.
I have made one windows phone based application. i want some designing ideas from you wp7 people.how can we apply styles,transparent background or the design which suits wp7 app. may i have some links which provides snaps for good designed apps. please help
One app that jumps to my mind when talking about great use and adaption to the metro design, it's "Cocktail Flow". It has very well done implementations of many design cues for WP7. As special treats it has features like parallax effects controled via gyroscope.
You can find a free version on the marketplace. Definitely worth a look.
MSDN user experience guidelines are pretty good, User Experience Design Guidelines for Windows Phone.
Also, it helps to install some popular apps from the marketplace and study their design.
The BEST thing you can possibly do to get a good idea of how to build a great WP7 app is to own a Windows Phone, and use it as your primary phone.
Get used to the way the operating system flows. Download cool apps. As time goes on you begin to understand from the user's perspective what a "good" app looks (and more importantly) feels like. It's a hard thing to nail down in a "user experience" spec. I find that a lot of people who set off to build a WP7 app do so before understanding how apps are supposed to behave on the platform. It is vital that you understand how users expect applications on the windows phone to operate. If you use a windows phone for a good 3-4 months, and really make an effort of butting it through the steps, it will be hard to walk away from that experience without a very clear idea of what a "good" application looks like for the windows phone.
That being said, and while I honestly don't believe that there are any short cuts to good design for the windows phone, I highly recommend downloading the following apps, and playing around with them to get a feel for "good" UI:
Wordament
Cocktail Flow (previously mentioned)
Twitter
Spotify
Yelp
Any of the built in applications (Office, Zune, Internet Explorer)
The above are good to start with, but again, you're really not going to understand it unless you live and breath it everyday for at least a few months.
Apple has a corporate developer program with an elevated licensing cost, does Microsoft provide such a service for Windows Phone 7 developers?
This was asked at a recent MS event. You can assign (I think 5) phones to developer unlock them, then load application directly/bypass the marketplace.
Also, there were talks that they are hoping to soon allow beta/redemption codes to allow limited deployment of your application to non-unlocked phones, bypassing testing/marketplace acceptance.... But I do not know the status of this.
The best thing you can do at the moment is develop your application as normal and have a password/login screen at startup. This is a horrible approach, but it does work.
At the moment, the phone is very much targeted towards consumers.
I'm not sure what is provided in the Apple Enterprise version, but so far Microsoft only has the one registration process and no private app distribution: you can distribute apps on the market to everyone, or by giving your xap file to people with dev-unlocked phones, nothing in between.
The official line is NO, not yet.
Windows Phone 7 was created, first and foremost, for consumers, not enterprise customers.
That being said, LOTS of people are asking for this and Microsoft have said they will address this in the future. No timescales or details have yet been announced yet.
This will likely be related to the way that beta testing and home brew distribution are implemented. (Just my assumption.)
I don't know why I can't just comment on another answer in this thread, so my apologies for placing these remarks in an answer.
I think MS needs to really make this happen since it could be the saving grace for WP7. While I personally feel that my experience with WP7 and my Samsung Focus have been just as good or better than that with the second-gen iPod Touch that I have, there are a lot of people who aren't convinced. For better or worse, it really is the ecosystem that matters and MS has that within the corporate world.
I would like to be able to show whats happening on my phone, on a computer screen or projector.
This seems like it must be possible since Microsoft does it in all of their demos, but I can't seem to figure out how.
For example, I've build an app, and I want to demo it to a room of prospective clients. I can't really use the emulator very well during a presentation. I'd like the room to be able to see what I'm doing on a big screen instead of all huddling around my phone.
I've asked various people at Microsoft about this and, unfortunately, the response I always get is that Microsoft is not able to load to load the necessary "VGA Patch" externally.
Unless you can do your demo in the emulator, cameras are the only way to go at this point.
What you've seen was done with internal hardware. Perhaps you could approach Microsoft to see if they are willing to assist in any way.
What Windows Phone 7 demo/reference applications have you seen which really made you interested in developing for the platform?
I know of Scott Gu's Twitter example and Foursquare. Also see here for MIX10 demo apps.
Other than developing games and re-creating functionality already present on other mobile platforms (iPhone, BlackBerry, Android), is there any good reference material and business benefits of developing for Windows Phone 7? Does the Silverlight dev environment really offer an advantage over what is already out there? My gut feeling is that this is definitely the case, but it will take some time for the platform to establish itself, if it does.
You can find a lot of examples and reference applications here www.reddit.com/r/wp7dev/ or search using the hashtag #wp7dev on twitter (full disclosure - some of my examples appear there).
There a examples of what people are openly working on, but one can assume it is a lot more - hopefully this is useful, as it shows what can be done, or is being done on the platform.
As a novice developer, other phone platforms came with a lot of overhead required to build even the simplest application. The fact that XNA will be available for game development is a huge thing for me, it means I can create simple games for me and my friends without having to spend time learning a new language or setting up awkward SDK's and deployment settings.
More advanced developers may scoff at that, but development tools that are already being used that can work right out of the box for the intended platform is important for the hobbyists. I think this will open up a huge arena for homemade games and apps just like XNA did for 360 development.
It should also help sales. I will buy a Windows 7 phone because of this, and I can imagine others will do the same. As it stands, I am going to port my existing XNA games over so I can play them on the go. It will be cool to show people at the office, airport, etc. projects I have made right on the spot, and even give them the option to play if they have the right hardware.
