Windows 10 - A Universal Windows Platform?

The Discussion

• 

  Windows 10 has been a pleasant surprise, faster and more sure-footed than 7.

  Hi,

  I need to flag that there's a 'bug' in this video :) I goofed on the day and forgot to include a piece of code that's really quite critical.

  At 12 minutes 43 seconds into this video I say "All you have to do is make a runtime check to make sure that it's ok to use the APIs that you want on a particular device family".

  At around 28 minutes into the video, I forget to actually do that. When I'm writing a function called DoSomeGpioWork() I should actually be wrapping all of that code in an IF statement that checks that it's ok to use the GPIO APIs. I could do that by checking at the API level or the Contract level and I'd usually use the contract level with some code like;

  if (Windows.Foundation.Metadata.ApiInformation.IsApiContractPresent(

  "Windows.Devices.DevicesLowLevelContract", 1))

  {

  // Do GPIO Work

  }

  I got away with this in the talk but it's important to flag that it was my mistake on the day and so I thought that I'd add it here to make sure it was clear.

   

  Thanks,

  Mike
