Hi, just bought your asset, all is working fine, including WP8 build, but not Windows Store build.
There is a bunch of errors like Method bla-bla not found in System.Type. I can try to send you full log on English, once i get non localized Visual Studio version, if you need it.
But i think you could fix it with easy, cause WP8 .Net Framework have mostly same restrictions as WSA 8.1.
Thanks for the purchase.
Please do send me the log when you are able, either here or at info@nodecanvas.com and I will take a look as soon as possible.
Thanks and sorry for this.
