Does YamlDotNet support trimming?

[TheRealQuantam]

Can YamlDotNet be used to deserialize classes with embedded classes (etc.) in apps that will be trimmed? If so, what if anything do I need to do to ensure that I won't have problems with things like constructors being trimmed (which I ran into with NewtonsoftJson)?

Yes it does. You’ll need to use the static builders and the Vecc yamldotnet static serializer nuget package.

There are some limitations though. The classes need to be public or internal along with the constructors. Constructors need to also be parameter less. Properties and fields also need to be internal or public. I don’t think record classes work either. One second and I’ll send you the tests around it so you can see how to do it

https://github.com/aaubry/YamlDotNet/blob/master/YamlDotNet.Core7AoTCompileTest/Program.cs Is a complete example of it. It references the static project directly which is packaged up into that Vecc nuget package.

Hmm. I'm trying it out and the generated context is running into issues. I have this (additional layers of inheritance not shown):

[JsonObject]
[YamlSerializable]
public sealed class FtLibraryInfo : LibraryInfo<FtModuleInfo, FtModuleGroupInfo> 
{
    [DynamicDependency(DynamicallyAccessedMemberTypes.All | DynamicallyAccessedMemberTypes.PublicParameterlessConstructor, typeof(FtModuleGroupInfo))]
    public FtLibraryInfo()
    { }
}

[YamlStaticContext]
[YamlSerializable(typeof(FtLibraryInfo))]
public partial class FtLibraryInfoStaticContext : StaticContext
{
}

The generated context code does not work, apparently due to not handling the generic parameters. It's trying to use the generic types rather than the types the class was instantiated with, e.g.

YamlDotNetAutoGraph.g.cs(666,64,666,70): error CS0246: The type or namespace name 'TGroup' could not be found (are you missing a using directive or an assembly reference?)

Is this use case supposed to work?

[TheRealQuantam]

The answer is yes, but not with generics (#1023).
