Type 'ReportingService2010' is not defined

When I run \samples\features\reporting-services\ssrs-migration-rss\ssrs_migration.ssrs, I get "Type 'ReportingService2010' is not defined":

rs.exe -i ssrs_migration.rss -s http://xxx:8888/ReportServer -u ReportViewer -p xxx -v f="/MikeDev" -v ts="http://xxx:8888/ReportServer" -v tu="ReportViewer" -v tp="xxx" -v tf="/test"

Start with samples/features/reporting-services/ssrs-migration-rss/ssrs_migration.ssrs and the supplied rs.exe command. Inspect the generated temporary VB around the ReportingService2010 references and the sample's reporting-services setup. Done means the sample compiles without BC30002 and can proceed past this type-resolution error.
