Microsoft has announced that developers can now add subscription add-ons to their Universal Windows Platform (UWP) apps on the Microsoft Store. Using new APIs, developers can set up in-app purchases with recurring billing in periods of one month, three months, six months, one year or two years. This also includes support for free trial periods of one week or one month so users can try out the add-on before committing to a subscription.

The one big thing to be aware of is Microsoft's store fees. According to Microsoft, developers will net 85 percent of the subscription price, while Microsoft will take a cut of 15 percent. Games, on the other hand, will see developers reaping 70 percent of the add-on subscription price, with 30 percent going to Microsoft.
