SP Web App

SP Web App

When I delete a SP Web Application from Central Administration, I cannot create a Web Application at the same address.  I also see that the IIS folder does not disappear:

  • C:\inetpub\wwwroot\wss\VirtualDirectories\mySite443

I try to delete the folder by hand, but the following file is locked:

  • Microsoft.SharePoint.WorkflowServices.ApplicationPages.dll

It gives an error:

  • The process cannot access the file
  • ‘C:\inetpub\wwwroot\wss\VirtualDirectories\mySite443\_app_bin\Microsoft.SharePoint.WorkflowServices.ApplicationPages.dll’ because it is being used by another process

Some people suggest iisreset, but the process is actually locked by PowerShell with SharePoint extensions.

Close all PowerShell and delete the file.
