Unable to copy file to server on build. Access to path is denied

Question

I have a solution in Visual Studio that is comprised of 5 projects. The projects build to assemblies (.dll). I have the output path of each project set to \my-web-server\wwwroot\bin, which works fine on one project. In the properties for all of my projects, I have the output path set to the same directory, but when I try building all but one of the projects, I get the error:

Unable to copy file "obj\Release\Index.dll" to "\my-web-server\wwwroot\bin\Index.dll". Access to the path '\my-web-server\wwwroot\bin\Index.dll' is denied.

I assume it could be an issue with permissions, because my organization keeps things locked down, but I have no control over granting permissions. Any help in the right direction is much appreciated.

Answer 1

It must've been something silly. I deleted the .dll manually, then rebuilt. Looks like everything's working normally. Thanks.

Answer 2

The solution for me was to delete everything in bin and obj folders in every project. Just ran this powershell script as described here.
