So I’m a bit of a stickler for fool-proof configuration, sometimes to my own detriment. In response to my earlier Bing Maps SDK issue with x64 I thought I would be really clever and just remove x64 as a target platform from the solution configuration. I thought it was clever. Heck, It was clever….too clever it seems.
It turns out that removing a Solution Platform from your solution will result in a rather unceremonious Visual Studio crash when you attempt to Create App Package for the store. The package utility seems to assume you have the default platforms configured; likely a safe assumption unless you have me for an end-user.
Luckily adding it back was quick and painless and the crash went away.
