Doing some Windows Phone 8 dev, I got a weird error some days ago. I was updating a WCF service reference when I got this :
After breaking my head, the culprit was the Phone Toolkit (at least the version 4.2013.8.16). Just remove the Nuget package, update the reference then add the package again will do the trick.
Just released two new app. If you’re into the promoro technique, this is for you !
