.Net Mirco Framework 2007技术大会
2006年在《程序员》杂志上通过看马宁的专栏文章,第一次知道了.Net MF。一年后的今天终于近距离地接触了.Net Mirco Frmaework,对MF有了一定的感性认识。
最近公司很多项目都有大量嵌入式设备使用,由于WinCE系统相对较大,对硬件平台要求过高,所以对.Net MF一直比较关注。今天总算大开眼界了。

微软公司的Colin Miller和Digi公司的John Leier在上午的演讲拉开了.Net MF序幕,针对嵌入式领域,一个从软件角度进行阐述,另一个从硬件平台角度进行呼应,一软一硬,二者强强联合,恐怕未来嵌入式智能设备一半以上的项目开发要被其收入囊中了。下午的中文演讲给人感觉有些干瘪,两三个演讲,平均短短十几分钟就草草收场。后来微软公司杜伟的演讲,从VS2005一行行难以看清的代码,到一个个令人惊艳的样例把MF开发技术推向最前台。

Digi公司很是有魄力,免费送出15套开发套件(5个作为回答问题的奖品,10个抽奖),自己即没有回答问题的勇气,也没有好的运气,只好剩下羡慕的份了。
最后为每个人送出的
1G
优盘(类似微软今年MVP大礼包中的优盘)很有分量,不仅是
1G
的容量,并且里面竟然把所有的幻灯片拷贝其中,更没有想到的是,MF 的SDK也在里面,真棒!
回到家迫不及待装了一份MF SDK(MicroFrameworkSDK.MSI 区区只有5998 kb,强!),有模拟器,也有示例。
![](https://p-blog.csdn.net/images/p_blog_csdn_net/yefanqiu/MF07091806.jpg)
其中几个示例不知道为什么编译成功,就是运行失败,对第二示例比较感兴趣,可以绘制图形,并且可以贴图。
