UtinyRipper VS IsExternalInit

it's made in unity3D so theoretically you could just use like utinyripper or something

You try older versions, but there are alternatives too. You can try UTinyRipper: https://github.com/mafaca/UtinyRipper / https://sourceforge.net/projects/utinyripper/files

OP hasn't heard of UTinyRipper (github) (youtube)

I think you can use uTinyRipper but I found a link to an archive where someone had used that (or a similar tool) and uploaded it all somewhere. I'll see if I can find it again.

If this is from an already built game you don't have access to, you can use some common Unity mod tools like Unity Asset Bundle Extractor: https://github.com/SeriousCache/UABE Or UTinyRipper: https://github.com/mafaca/UtinyRipper Just note these are not guarantees and sometimes takes a decent amount of time and effort to get what you are looking for.

Head to here,github repository of uTinyRipper.

You can also just reference the https://github.com/manuelroemer/IsExternalInit NuGet package.

init only properties (likely to come up if you use records) - you can either use the IsExternalInit nuget package or manually define the attributes - either way, the feature works perfectly fine

…and a NuGet reference to https://www.nuget.org/packages/IsExternalInit, I can then do public record Foo(string s); and have it build.

You only need https://github.com/manuelroemer/IsExternalInit for that (and to set LangVersion).

Even for .NET Framework code, I tend to use recent C# versions. I reference https://github.com/jnm2/ReferenceAssemblyAnnotator to get nullable support and https://github.com/manuelroemer/IsExternalInit for records, and that takes care of most of the features I care about.

features that require BCL additions. Since you're on the older BCL, those will need to be backported. For example, to use init; and record, you can use https://github.com/manuelroemer/IsExternalInit.
