I am trying to execute a script from my .NET code. This usually works for anything else. But, in regards to the following,

SET ANSI_WARNINGS OFF
DBCC ShrinkFile (LevelExtreme_Log,1)

I obtain this message:

"Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information."

My project is showing the following, as attached.

So, as you can see, my EXE is 4.0. My doubt is that the Microsoft. SQLServer. something are not up to date. I run SQL Server 2008. I am able to do this however:

Dim loBackup As Backup = New Backup
Dim loServer As Server = New Server

loBackup.Devices.AddDevice(cPath + "\" + cDatabaseName + ".bak", DeviceType.File)
loBackup.Database = cDatabaseName
loBackup.Action = Microsoft.SqlServer.Management.Smo.BackupActionType.Database
loBackup.Initialize = True
loBackup.PercentCompleteNotification = 1

AddHandler loBackup.PercentComplete, AddressOf ProgressEventHandler
loBackup.SqlBackup(loServer)

So, it seems to be related to the data provider, as that script is executed through it. Anyone would have any idea on what is causes this?
