Windows 8 Apps : Guidelines

Recently we are trying to push a few of our apps on to windows 8 app store. Before we push the apps the store the app needs to undergo some basic guideline checks.

Microsoft team definitely does those checks , but you can also ensure that your app adheres to all the guidelines set across. To do this we follow a two step process.

Step 1: Run certification kit on your app.

Step 2: Ensure that your app adheres to all the Windows store guidelines set at msdn.

I have captured them here for my reference. You too can use this.

You can also download the document from gdocs.
