✅ Ported an app to .NET 7, rebuild all my dependencies, app refuses to load them

READ THIS FIRST: I tried all the typical debugging methods such as assembly binding logs and whatnot, to little to no results. This isn't easily solved with google. Hey everyone, I was porting an app to .NET 7 (from .net framework 4.6), and I keep having an assembly not found exception from my dependencies. I tried ProcMon and tools that show me the assembly binding failures, but for some reason nothing shows there. I also tried Dependency Walker but it just freezes while loading them. I'm not sure if the host that runs the app (since modern .NET uses an app host to actually run the app) is preventing this from going to logs and therefore it's being very hard to debug. I also have other issues with VS2022, where it either randomly (not always) fails to build due to metadata file missing for my main dependency (even tho it's being built in one of the projects that errors with that, multiple attempts to build usually "fix" that), and also where the main dependency's project shows warnings about the types I create there being found in two places (which are the dependency in both cases). I tried doing dotnet publish for the 3rd party dependencies, so not sure if that's related? I'd really appreciate some help here as I never went beyond .NET Framework until now. Thank you very much for your help!

can you tell us exactly what the errors are?

I know this can happen from a missing dependency inside the dependency (glfwnet in this case depends on glfw but glfw is in the same folder)

ero•2y ago

how do you mean "in the same folder"? are these not 2 projects in the same solution?

AureliusOP•2y ago

glfwnet in this case is a separate dependency I built, not in the same solution however glfwnet is located in the same working directory folder for the project in the solution

Angius•2y ago

So it's some random loose .dll?

AureliusOP•2y ago

so the Player should be able to see it yeah but for some reason I can't get an answer as to which DLL it is it's also set as a dependency of the Player project, so it's copied around on build

ero•2y ago

what is this project setup lol

AureliusOP•2y ago

assembly binding logs don't show for this, and dependency walker freezes when analysing the DLL it's a game engine, I got a dependencies solution for building 3rd parties, and a Engine solution for building the main engine projects the engine solution has the Player, Core, Editor, and Editor App both the Editor App and Player fail to run due to this error

Angius•2y ago

Well, I won't be of much help. I never reference loose .dlls, I either use Nuget for dependencies, or just reference the project itself

AureliusOP•2y ago

it's likely a native dependency that's failing to load this error can appear when an assembly's dependency fails to load

ero•2y ago

is this a runtime error?

AureliusOP•2y ago

yeah

ero•2y ago

then... i guess the .dll is just not set to copy to output...?

AureliusOP•2y ago

the related DLLs should all be copied directly to this folder problem is I can't figure out which DLL is missing because the tools I would use to figure this out aren't working the assembly binding log is empty, and dependency walker freezes

ero•2y ago

it's really not clear at all what you're doing

AureliusOP•2y ago

okay I built my project all the dependencies are in the spot when I try to open it, it fails to run due to a dependency not loading I can't figure out why because the tools you would use for this don't work for giving details of the problem

ero•2y ago

What project. What are you building. What's the full setup. What dependency is missing. Where are you getting it. Why could it be failing. So much info missing

AureliusOP•2y ago

^ I'm using VS 2022 and C# some dependencies are native and are imported as native DLLs I don't know what dependency is missing, because the tools I used so far don't tell me however I just used asmspy to list my assembly references at least and solved some of the problem now only one of the projects doesn't work Newtonsoft.Json was for .NET 6 while I was using .NET 7, so I recompiled it to 7 and now at least the Player project works. the Editor project still doesn't work unfortunately.

Oh what the fuck. I thought that glfwnet project was the one they're making See this is what happens if you don't explain properly

ero•2y ago

you can't even have a "native" dependency in c# can you? or would you consider a library that you P/Invoke a "dependency"?

AureliusOP•2y ago

Glfwnet depends on glfw to work, and at least at the time didn't have net7 version Newtonsoft json also doesn't have a net7 version on nuget

ero•2y ago

why should it? why would you use it, anyway? newtonsoft has a net6.0 version, that's gonna work just fine with net7.0

AureliusOP•2y ago

Newtonsoft was failing to load for me

ero•2y ago

that's a you thing it definitely works but you don't even want to use newtonsoft in net7.0 it's absolute dogshit (and that's putting it lightly) compared to STJ on that version

AureliusOP•2y ago

Newtonsoft was failing to load because I had two assemblies using two different versions of another assembly (since newtonsoft was 6 and my other assembly 7)

ero•2y ago

doesn't make sense

AureliusOP•2y ago

I already tried using asmspy, ilspy, procmon, fusion, dependency walker, and I still can't figure out why my editor DLL won't load I even tried removing most of its code and it still doesn't work the only dependency it has is my Core project, which works since my Player project runs

ero•2y ago

do you wanna share literally any part of your project setup any code your project files anything at all

ero•2y ago

yeah this is a very... unusual? project setup... you include dependencies using their built binaries, what are you doing just use nuget packages

AureliusOP•2y ago

the nuget packages don't have net7 versions

ero•2y ago

it doesn't matter

AureliusOP•2y ago

it was failing to load, so it does matter

ero•2y ago

if they're compatible, they're compatible it does not matter. You're clearly messing something else up in your project setup for it to not work

Accord•2y ago

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.

AureliusOP•2y ago

I accidentally figured out the cause: Apparently, dotnet projects don't like having their bin/obj shared. By moving the projects to each source subfolder, all the problems seem to have been fixed!
