 Whovian9369 | Yeah it seems to be setting TargetFramework to net8.0 in build/_build.csproj so I'll need to patch that and possibly update Nuke.Common in the same csproj
<PackageReference Include="Nuke.Common" Version="8.0.0" />
| 03:49:50 |
| Corngood | Try the roll forward options from that link first. It may be fine to target 8 and run on 9 | 03:51:02 |
| Whovian9369 | Would you say the best solution is likely via env.DOTNET_ROLL_FORWARD = true? | 03:51:35 |
| Whovian9369 | * Would you say the best solution is likely via env.DOTNET_ROLL_FORWARD = "LatestMajor";? | 03:51:57 |
| Corngood | I'd give that a try at least | 03:52:35 |
| Whovian9369 | Good news is that Nuke ran, but throws...

| Corngood | > Starting in .NET 9, the in-box BinaryFormatter implementation throws exceptions on use,
Ugh. Maybe you need to build this with net8 runtime available. | 04:10:07 |
| Whovian9369 | Sounds like the best plan unfortunately, thanks. Happen to have a link to where the quote's from, please? | 04:10:39 |
| Corngood | https://aka.ms/binaryformatter | 04:11:04 |
| Whovian9369 | Either way, I was playing whack-a-mole with Nuke 9.0.x, so I wasn't having any luck with my plan either.
warning NU1603: Nuke.ProjectModel 9.0.3 depends on Microsoft.Build (>= 17.11.4) but Microsoft.Build 17.11.4 was not found. Microsoft.Build 17.12.6 was resolved instead. | 04:11:32 |
| Corngood | You can use combinePackages to combine the 8 runtime with the 9 SDK, or both sdks | 04:11:48 |

| Whovian9369 | So separate dotnet-{runtime,sdk} wouldn't work for the former? | 04:12:46 |
| Corngood | I don't think it'll work because the muxer can't find it and only one will be in the path | 04:13:32 |
| Whovian9369 | I'll probably have to mess with that on my own then, bleh. Thanks for the time! | 04:14:13 |

 Emma [it/its] | huh, i gotta build dotnet 10 from source | 23:55:59 |
| Emma [it/its] | that doesnt sound very positive | 23:56:29 |
| Emma [it/its] | ah, seems it failed on hydra, and logs arent available: https://hydra.nixos.org/build/308971738
was cancelled though | 23:59:38 |
| 6 Oct 2025 |
| Corngood | https://github.com/NixOS/nixpkgs/issues/431811. I haven't been able to get a core dump or find a way to reproduce it. | 00:11:05 |
| Emma [it/its] | 
Download clipboard.png | 13:35:03 |
| Emma [it/its] | thought it would take more than half an hour to build dotnet-sdk 10 lol | 13:35:14 |
| Emma [it/its] | was unable to reproduce here too | 13:36:01 |
| Corngood | If anyone has more rights than me on hydra, that might be helpful for reproducing this, or possibly getting a core dump. I've tried poking around with various system limits, but I'm not quite sure what to try next. | 14:02:20 |
 tris203 | I can reproduce in a garnix builder. The garnix guys did say they could help get logs from their builders. But then went quiet | 14:52:58 |
