Windows Store app Development Snack: Knowing your (memory) limits, will avoid problems in the store!
For more posts in this series, see the series index.
Here is a interesting requirement of Windows Store apps – they must run on a low-power computer, and if (like me) fail this you get the error message you see in the screenshot which suggests a test tool exists.
The problem with this tool is it can only test HTML apps :/ The question is then, what can XAML developers do to help avoid this situation? Use task manager – really. It is that easy! Just watch your memory usage while using your application once you have that there is two things you can do.
At the bottom of the Selling details page is the option to specify if you need more than 2Gb of RAM – which feels really high for the types of apps I build, but maybe worthwhile to those developing games. If you are over 2Gb of RAM, make sure you set that.
The second location is under the Description page which has a completely optional Recommended hardware
Here is some free form space for you to put in conditions about the application including things like disk space & memory usage. I resubmitted the app that failed originally with just this specified and it passed, so it appears that this is taken into account.
