Very specific question about AssemblyLoadContext and Assembly Resolution
So a bit of context: I'm developing a plugin system for modding a game (hopefully this is allowed here).
It has a native dll which hosts the .NET 8 runtime using hostfxr. Then there are 2 assemblies A.dll and B.dll
- A.dll is loaded into the default ALC by the native dll using
- B.dll is loaded into a unique custom ALC created by A.dll
- B.dll then loads plugins into their own custom ALCs (one ALC per plugin)
Inside all of those ALCs I'm using
Now I tried creating a WPF assembly and I'm having two issues:
1. Since
However the default ALC fails to resolve these assemblies for some reason. (Throws
2. I tried brute-forcing it by simply manually resolving the path to
Here is the exact exception thrown:
For reference: I have also attempted this with WinForms. It also had the first issue of not being able to resolve the dependencies, but for that the brute force approach worked.
I am honestly stumped here and would really appreciate some help. I can provide source code as well if necessary.
