安装完CE6后，会发现Platform Builder for CE5的Connectivity Options不好用了，即使修改设置后点Apply也无法把新设置保存住
在完全卸载CE6和VS2005后，点PB5的Connectivity Options会弹出这个错误
即使把CE5和PB5完全卸载，然后再重装，改错误仍然存在。
我在网上搜到了该问题的解决方法

为了防止这个网页哪天就不见了，我还是把那些内容COPY到自己BLOG里比较安全，嘿嘿
1) Shutdown all instances of PB (version 5.0 and later) and make sure
Cepb.exe, CeSvcHost.exe (CeSvcH~1.exe) and DeviceEmulator.exe are gone from
the task manager.
2) Back up the C:\Documents and Settings\<user>\local settings\application
data\microsoft\corecon folder //我就直接DELETE掉，不用BACKUP了
3) Purge that folder [This will destroy all previously configured device
settings. It is important to make a backup as in step 2 if you need to
retain the other device settings and revert back].
4) Back up C:\Documents and Settings\all users\application
data\microsoft\corecon\1.0\addons folder to something outside of //同样，直接DELETE掉
5) Purge that addons folder under the corecon\1.0
6) Create a new one by that name under the corecon\1.0 folder
7) Copy C:\Program Files\<PB Install folder>\CoreCon\SDK\XSL\Addons\*.xsl to
the new ...\coreCon\1.0\Addons folder you created.
8) Also copy C:\Program Files\<PB Install
folder>\CEPB\bin\microsoft.platformbuilder500.servicecategory.xsl to the
above addons folder.
9) Relaunch PB and try creating and configuring a new device.
该方法经本人验证，正确可用。很显然，CE6修改了core connectivity的方法，但是在卸载时却没有清理干净。
