Describe the bug
With the new path release of .net 6, our build times increased significantly.
A dotnet publish that takes under one minute with .net 6.0.402 now takes about 50 minutes with .net 6.0.403
We see this behaviour in our self-hosted agents (running Ubuntu) but I can also reproduce this locally on Mac M1.
- script: dotnet publish --force -o bin
workingDirectory: EndToEndTests
displayName: Copy artifacts
To Reproduce
Unfortunately this does not seem to reproduce on small example projects. But I am happy to run the CLI or the Azure pipeline with added diagnostic if that helps.
Further technical details
Pipeline log with timestamp:
2022-11-15T09:33:58.3747979Z project1 -> /agent/_work/2/s/Backend/p1/project1/bin/Debug/net6.0/project1.dll
2022-11-15T09:33:58.6882283Z project2 -> /agent/_work/2/s/Backend/p2/project2/bin/Debug/net6.0/project2.dll
2022-11-15T10:23:29.7324711Z project3 -> /agent/_work/2/s/Backend/p3/project3/bin/Debug/net6.0/project3.dll
2022-11-15T10:23:29.7734805Z project4 -> /agent/_work/2/s/Backend/p4/project4/bin/Debug/net6.0/project4.dll
So it seems to be one project that takes long (out of 90 or so) but it is not always the same project.
Locally, I ran dotnet build and this is what I got:
➜ ATS2 git:(dev) ✗ time (dotnet build) > /dev/null
( dotnet build; ) > /dev/null 6.99s user 3.15s system 102% cpu 9.854 total
