I am not sure why npm install would interfere with this at all. Do you have any customization in your project that might be causing this?
Could you share with us a binlog? dotnet build /bl, should generate a .binlog file that you could share with us. Do notice that if you do, the binlog logs secrets and things like that, so make sure you don’t have any in your build before sharing.
Without a binlog or a repro we can reproduce ourselves, there isn’t much we can do.
You can try setting
<GenerateAssemblyInfo>false</GenerateAssemblyInfo>
in your project, so see if the file stops being generated and your build succeeds.I am going to close this issue then. Thanks.
