sdk: Publish failed due to Unable to copy file

Describe the bug

i’m trying to publish a webjob to Azure but I get some errors like the following. looks like it’s because in the path after ‘Out’ it adds two backslashes instead of one (PubTmp\Out\\app_data).

@kylemcnee I had the same issue but fixed it thanks to @joeloff comment. You can add these 2 lines to your publish profile to use different (shorter) paths during the publish: <PublishIntermediateTempPath>D:\Temp\VS2019\MyWebJob\Tmp\</PublishIntermediateTempPath> <PublishIntermediateOutputPath>D:\Temp\VS2019\MyWebJob\Out\</PublishIntermediateOutputPath> Hope this helps.

This has been blocking my work for over a year at this point. If you’re reading this, be warned! Do anything you possibly can to avoid working with .NET

I’ve been blocked by this for six months, it’s complaining about bootstrap files and i think it’s because of a character limit. There’s nothing I can do to shorten the path lower than 256 characters.

I juts hit the same issue publishing a Asp.Net Core 3.1 web job from VS. It appears it is related to the length of the target path when copying file to the TempPub folder. It seems that when the path exceeds 256 characters it will cause the publish error. I was able to resolve the issue by simply shortening the name of assemblies and/or the web job name.
