I shutdown the sqlserver service，then，successed。
Thank you for writing such a good book！

Visual Studio may have a lock on these files. Try one of these:

1. On the Server Explorer / Database Explorer, try disconnecting from SQL Server
2. Or, on the Publish Wizard, choose the option to ignore items from App_Data

Hope this helps,

Imar
