Can't delete custom SharePoint webpart DLL

Question

Hi All,

I've created a couple of custom web parts and put the DLLs in the /bin folder for testing. I now want to delete the DLLs from the /bin folder but I keep getting the following error:

Cannot delete xxxxx: Access is Denied Make sure the disk is not full or write-protected and that the file is not currently in use.

I can rename the DLL files, so they arent completely locked, however if I do I get the error Could not load file or assembly 'xxxxxx' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) displayed in the browser when load the site.

Any ideas?

Thanks,

Charlie

Answer 1

Take a look at the "deleting web parts" section of this document, it explains the process for removing the webpart so it is not referenced any more: http://technet.microsoft.com/en-us/library/cc288254.aspx

Answer 2

They are probably locked by IIS. Try this:
iisreset /stop
(delete them)
iisreset /start

Answer 3

dar - I'd tried that already, but it didnt work. I think the reason was that it was a dll in the bin folder rather than a web part that had been deployed to the GAC

strongopinions - iisreset /stop - iisreset /start worked grat. Thanks alot.
