An error occurred processing a PUT request to http://xxx/nuget/all: The process cannot access the file

[Trishan]

Good day,

We are having an issue where ProGet server is throwing "the process cannot access the file" errors. The file in question is within the "C:\ProgramData\ProGet\Packages.nugetv2\F2" folder.

The stack trace is as follow:

System.IO.IOException: The process cannot access the file 'C:\ProgramData\ProGet\Packages\.nugetv2\F2\ACME.Shared\ACME.Shared.0.2.19.nupkg' because it is being used by another process.

Any leads would be greatly appreciated.

The error is "The process cannot access the file 'C:\ProgramData\ProGet\Packages.nugetv2\F2\ACME.Shared\ACME.Shared.0.2.19.nupkg' because it is being used by another process."

That error is coming from Win32, and will happen when another process tries to lock a file. Most likely, this other process will be an indexing service or anti-virus tool that is scanning/locking the file as soon as proGet starts writing to it.
