Unable to open the physical file "g:\inetpub\wwwroot\learn\App_Data\Personal.mdf". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)".
An attempt to attach an auto-named database for file g:\inetpub\wwwroot\learn\App_Data\Personal.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

If you have Personal MDF opened in the Sever Explorer try disconnecting and then running your page again.|||
