Microsoft BUILD 2012 – Tips

With the announcement of BUILD 2012 I thought I would put together a list of tips – mainly aimed at fellow developers from the UK but there may be something here for everyone!

Accommodation

If you are on a tight budget and can book early try the Homestead Suites.   It is next to the Microsoft Campus and very reasonably priced (especially if you can book for a week).

I have also stayed at the Extended Stay America – there are a couple within a short drive of the Campus, again cheaper if you stay for at least 7 days. 

Both the above are self catering and include a basic Kitchen complete with utensils/cutlery/fridge/hob & cooker (and WiFi access).

NB Don’t be tempted to go ‘real cheap’ and stay too far away from Redmond / BelleVue.  The traffic gets really bad around Seattle and you may live to regret it – especially if you are a little jet lagged! (I speak from experience!)

On Campus

February 2003 012Try and find a friendly Softee to show you around.  I have been lucky in the past and have seen a few ‘geek treasures’ that I would never have found (or had access to) myself.

Unable to connect to the Windows Store

 

Just documenting an issue I have been having this morning when firing up the Windows 8 Store.

At first I get the familiar splash screen: “Getting the store ready for you”

image

But then after a few more seconds I am presented with “This might take a while longer”:

image

Before finally being hit with “We weren’t able to connect with the store”:

image

This looks to be some sort of connectivity issue but the rest of the internet seems to be behaving itself.

Is anyone else experiencing the same issue or have an explanation?

I am based in the UK.

(Needless to say I have already tried this several times this morning after ‘waiting a few minutes’)

Tip – Marketing Your Windows 8 Apps

846x468

When it comes to submitting your Windows 8 Apps there is quite a list of marketing graphics that you can submit:

The only mandatory one is the 416×180. It occurred to me that this size would be great on a T-Shirt.  Happily Vistaprint in the UK are currently doing an offer to get a T printed for 99p Plus P&P (So if nothing else check out the virtual T-Shirt design for free! )

TShirt

The next step involves being seen with your T Shirt.  I was lucky enough to be offered the chance to go on the ‘Gadget Show Tech tour of London’ yesterday and the crew were a really friendly bunch (Polly Woodward & Jason Bradbury)

(Look out for me wearing the shirt on the Gadget Show later this Summer*)

So much for the 99p T-Shirt:

The Native Image Generator failed

When submitting an App to the Windows 8 store I am repeatedly getting an error that relates to the failure of the native image generator.

There are a number of suggestions around this issue in this article which having worked through, and submitted an issue via  Connect (see here) I have finally implemented the suggested workaround:

As a last resort, you can disable automatic native image generation for your app by including a file that is named "nongen.txt" in your app package. Be aware that doing this may adversely affect startup and execution times for your app. Make sure that you file a Connect bug before you take this step.

This then resulted in an overall WACK pass:

Windows 8 Store Certification Failure

After around 10 days in the submission process my first Windows 8 App has failed with the following report:

image

6.11 The app’s category and subcategory must correspond to the character or purpose of your app

Presently the Apps’ category and sub-category are:

image

Which is as I intended (there is no sub category for ‘Productivity’ Apps).

My thinking was that this App helps you be more productive with your Windows Phone and I must admit, looking at the other options this still looks to be the best in my opinion.  It is a shame that there was not a sentence indicating the thinking behind the reason for failure or perhaps a suggestion as to where Microsoft thinks my App should live?

I found it a little disappointing that any other ‘issues’ with the App are not listed (or alternatively there is a section that states that ‘no other issues were found’) as this would be useful as well as giving us an indication of whether this process is  ‘fail at the first hurdle’ or is more comprehensive.
