deploy时提示：
error ocurred in deployment step 'add solution': failed to load receiver assembly 'microsoft.office.sharepoint.clientexentions.dll....
这个异常只会在wss中发生，解决办法是：
前提：两台机子，一台是wss4.0，另外一台是moss2010，vs2010
1，从moss的服务器，把
1) microsoft.office.server.dll
2) microsoft.office.sharepoint.clientextensions.dll
3) microsoft.office.sharepoint.clientextensions.xml
三个文件从isapi folder中（可以从iis application的vti_bin中explore）复制到 wss的 isapi文件夹中
2，把两个dll加入到vs2010的bcs 项目中的package中去（在designer advance 中设置）
3,
build--> deploy solution,当有提示说是否修改web.config, 选择修改。
确保你deploy的web application中的web.config有如下字样：
<safecontrol assembly="microsoft.office.server.chart, version=14.0.0.0, culture=neutral, publickeytoken=71e9bce111e9429c" namespace="microsoft.office.server.webcontrols" typename="*" safe="true" safeagainstscript="true" />

ps：wss4.0 = microsoft sharepoint foundation 2010
