unable to cast object of type 'Microsoft.SharePoint.SPsite' to type 'Microsoft.SharePoint.SPWeb'

ERROR:unable to cast object of type 'Microsoft.SharePoint.SPsite' to type 'Microsoft.SharePoint.SPWeb' during deploy MOSS 2010 solution

 

原因：程序中有涉及到spweb的引用，註釋掉就可以了。

            //SPSite curSite = (SPSite)properties.Feature.Parent;
            //SPWeb curWeb = curSite.RootWeb;
            SPWeb curWeb = (SPWeb)properties.Feature.Parent;

如果是想發佈到web上，將下面的scope設置爲web
