(关于近期许多朋友各种提问我没有回答的说明:

首先小梦还是个有起码礼貌和素质的人,一般提问即使没有问答.我也会回复下,但最近真心很忙.小梦每天过的都蛮紧张的.所以最近许多的朋友的提问我都没有回复,在这里向大家道个歉,说明下.希望理解!不是小梦装逼,而且真心时间有限.希望初学者能认证看看之前我的博客还有论坛我发的有用的文章,资料.

其实我的论坛的内容已经把国内所有的windows phone 8.1开发的最新资料都包含了,而且加上我的博客估计目前是国内windows phone8.1开发资料最全的!希望大家都能在论坛活跃下,帮忙推广下.大家有问题相互帮忙下.大家的问题基本是我一个人再回答.而我的精力肯定是有限,社区本来就是互相帮助的!

过一段有时间我会把我目前所有的资料和源码在整理一下.

其中几个比较全的完整应用源码将免费送给向我捐赠和论坛积极回答大家问题和推广论坛的朋友.)
