The error is caused because IronPDF causes two files with the exact same RelativePath to be included(see screenshot below), preventing the publishing process from completing successfully. Here's some information about this: dotnet/sdk#3465 (comment). Log file msbuild.binlog generated during publish process can be read with https://msbuildlog.com/.
