 lostmsu | JamieMagee: I pinged you as I had a similar PR open for a while. I also bump SDK to .NET 10 (so that we won't have to touch this for a while). | 23:25:02 |

 Whovian9369 | Hello! What exactly should I do if I go to build a derivation and run into this error?
ln: failed to create symbolic link '/build/nuget.1U96kM/fallback/microsoft.netcore.app.runtime.linux-x64/8.0.23': File exists
| 19:55:31 |
| Whovian9369 | Oh it's likely something to do with repeated entries in deps.json - I'll see if regenerating that fixes it! | 20:00:53 |
| Whovian9369 | Yep, that was it - Whoops. Oh well, apologies! | 20:02:17 |

 Emma [it/its] | hm, i wonder why buildDotnetModule would... ignore a deps.json file? | 04:04:30 |
| Emma [it/its] | particularly, i did the fetch-deps stuff, the deps.json isnt empty, its staged into git, its referenced in my derivation, yet it complains it cant find any dependencies | 04:08:12 |
| Emma [it/its] | cleared out the deps file and i noticed that it doesnt even seem to write to it, it just does nothing | 04:36:02 |
 Corngood | fetch-deps can only write directly to a deps.json when it's evaluated impure. Maybe you're evaluating it through a flake? In that case you can pass it the output path as a command line arg | 14:22:32 |

| Emma [it/its] | that's what im doing already | 23:40:09 |
| Emma [it/its] | hence it not making sense that it just... returns [] | 23:41:03 |
| 23 Feb 2026 |
| Corngood | You can run `fetch-drv` in a dev shell and then see what ends up in the nuget packages dir. | 00:54:11 |

 Waldemar Tomme (they/them) | Hi, I'm trying to run a locally installed .NET tool (according to nuget.org it's targeting .NET 8 and 9) and I have globally installed .NET SDK 8, 9 and 10 (combined). When I try to run the tool dotnet is requesting v9 but only finds v10. If I drop into a nix shell with dotnet-sdk_9 it works but why doesn't it work with the combined SDK? I need to use it in my .NET 10 project as part of the build process. | 10:04:34 |
| Waldemar Tomme (they/them) | Ah, wait, it works in the build process but still not when I try to invoke it directly. At least I can work with it for now but still weird that the direct call doesn't work. | 10:10:13 |

We should really get that fixed... | 11:46:24 |

 Samuel | That issue has been bothering me for a while as well, but I don't know how to fix it. | 22:29:30 |
| Corngood | Well I think the brute force option would be to stop using symlinks to combine sdks/runtimes, but I hate that | 23:45:16 |
| 3 Mar 2026 |
| Samuel | So like copy all the sdks together into a giant directory? | 00:28:44 |
| Samuel | Yeah that wouldn't be great. | 00:29:03 |
| Corngood | Well I think the problem only occurs when you use `combinePackages`, right? And it happens to use symlinks | 00:36:41 |
| Whovian9369 | Anyone know how git-based fetchers work with repo tags? I have (someone else's) dotnet app building that is seemingly pulling an existing but old tag for VersionInfo.Version and I can't figure out how :P | 04:14:58 |
| Whovian9369 | I'm using the latest commit on master and not one on the tag, so I am a bit stumped on this. | 04:15:50 |
| Corngood | It's hard to imagine it's related to the fetcher itself? Is it set to keep .git? Is it something you can share? | 15:13:30 |
