解决CE6和CE5在Platform Builder的Connectivity Options上的冲突

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。
