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：

问题解决~~
PS：WSS4.0 = Microsoft SharePoint Foundation 2010
