WebDeploy with MSdeploy.exe fails to sync GAC Assembly because dll(s) locked by another process

I'm having this problem using msdeploy to sync GAC assembly to many Application Servers.

When I run this command

msdeploy -verb:sync -source:gacAssembly="'MyAssembly'" -dest:gacAssembly,computername=DESTINATIONSERVER

I obtain this error:

*Microsoft.Web.Deployment.DeploymentException: (28/09/2010 16.46.37) An error occurred when the request was processed on the remote computer. ---> Microsoft.Web.Deployment.DeploymentClientServerException: An error was encountered when processing 'INPS.DNA.dll'. ---> Microsoft.Web.Deployment.DeploymentException: The error code was 0x80070020. ---> System.IO.IOException: The process cannot access 'C:\Windows\assembly\GAC_MSIL\MYASSEMBLY\1.0.0.0__a31fe99d2f98435c\MYASSEMBLY.dll' because it is being used by another process. at Microsoft.Web.Deployment.Win32Native.RaiseIOExceptionFromErrorCode(Win32ErrorCode errorCode, String maybeFullPath) at Microsoft.Web.Deployment.FileStreamEx.CreateInstance(String path, FileMode fileMode, FileAccess fileAccess) at Microsoft.Web.Deployment.FilePathProvider.Add(DeploymentObject source, Boolean whatIf) --- End of inner exception stack trace --- --- End of inner exception stack trace --- at Microsoft.Web.Deployment.DeploymentObject.Update(DeploymentObject source,DeploymentSyncContext syncContext) at Microsoft.Web.Deployment.DeploymentSyncContext.HandleUpdate(DeploymentObject destObject, DeploymentObject sourceObject) at Microsoft.Web.Deployment.DeploymentSyncContext.SyncDirPathChildren(DeploymentObject destRoot, DeploymentObject sourceRoot) at Microsoft.Web.Deployment.DeploymentSyncContext.SyncChildrenNoOrder(DeploymentObject dest, DeploymentObject source) at Microsoft.Web.Deployment.DeploymentSyncContext.SyncChildrenOrder(DeploymentObject dest, DeploymentObject source) at Microsoft.Web.Deployment.DeploymentSyncContext.ProcessSync(DeploymentObject destinationObject, DeploymentObject sourceObject)

If I execute IISRESET on DESTINATIONSERVER the error doesn't occur!

My question is:

It's possible to unlock DLL without perform an IISRESET command?

I think I can avoid to restart entire Web Server.

Can you help me'

Thanks a lot!

Best regards.

What about using the recyleApp provider to stop and start the app pool?

msdeploy.exe -verb:sync -source:recycleApp -dest:recycleApp="Default Web Site",recycleMode="StopAppPool",computerName=remote-computer

... do your real deployment ...

msdeploy.exe -verb:sync -source:recycleApp -dest:recycleApp="Default Web Site",recycleMode="StartAppPool",computerName=remote-computer
