Roslyn compiler is being copied to the wrong folder

Good day everyone,
  I am using the octo.exe cli tool as part of a build pipeline that I am implementing for a project that i am working on to learn Dev Ops. The project consists of an web app and a console application that will be deployed as a windows service using top shelf. The web project uses the roslyn compiler; When I package the web application the csc.ex and its related files are cpoied in the root of the bin directry as well as in the roslyn folder that's location in the bin directory. Using the octopack nuget package seems to put the roslyn files in thew correct location (only in the roslyn folder), however some dependencies (class libraries) are not included in the out put.

Can someone provide some guidance on how I can resole the issue (preferably using the octo.exe cli).

    Thanks for getting in touch. I think this would be a scenario where you would have to stage the build output into a folder with the correct content and structure, and then run octo.exe against that folder.

    Could you provide any more detail in the way of a build log or sample project or anything? Octo.exe should simply be zipping the folder you point it too, so I'm just trying to work out which piece is causing the csc.exe to be copied into 2 places.

    I think you're correct, I am outputting the application to a specific folder and the csc.exe is indeed copied to both the root of the bin folder and the Roslyn folder in the bin. Not sure why that's happening.

    Could I just check which version of the Roslyn Code Dom Provider you are using? We've had another report of an issue that relates to a bug that with the Roslyn package, see

    I'm not sure if this is related to your issue, but given it relates to that same folder not being handled correctly, it is possible.
