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

Question

Hi all,

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
