昨天微软终于（突然）发布了Windows Mobile SDK 6.5，有中文版可供下载，不过遗憾的是仍然不支持VS2010。详见：

更新1：Waggener Edstrom, 微软的公关代理，表示说 "on Friday, January 22nd Microsoft prematurely posted a version of an upcoming Windows Mobile 6.5 SDK to a public facing Web page. While the SDK was not announced or promoted, it was discovered and generated questions from the community. The beta SDK has since been removed. To provide the best experience possible for Windows phone developers, the SDK will be reposted once final testing has been conducted. We apologize for any inconvenience".
