This can typically happen when the project was not built or there are older project dlls in bin/ (for example from previous .NET versions) - can you check if any of this is the case?

Hi, I have the same issue when trying to use this package. I'm using a GenerationSpec file instead, in my case it cannot find the Spec file.

TypeScriptGenerationSpec.cs

NOTE: Im just testing so the barrel thing is probably wrong, but it does not even get here anyway.

    public class TypeScriptGenerationSpec : GenerationSpec
    {
        private static string _namespace = "myProject.Models";
        public TypeScriptGenerationSpec()
        {

        }
        public override void OnBeforeGeneration(OnBeforeGenerationArgs args)
        {
            foreach(Type type in GetType().Assembly.GetLoadableTypes()
                .Where(x => x.FullName!.StartsWith($"{_namespace}.Identity.Models")))
            {
                AddClass(type);
            }
        }

        public override void OnBeforeBarrelGeneration(OnBeforeBarrelGenerationArgs args)
        {
            AddBarrel(".", BarrelScope.Directories);
        }
    }

More Info

I played around a bit with the GenerationSpec name changed it to GenerationSpec : TypeGen.Core.SpecGeneration.GenerationSpec and got the exception: System.MissingMethodException: Cannot dynamically create an instance of type "Type.Core.SpecGeneration.GenerationSpec". So I think there is something wrong with how your resolve the GenerationSpec file from the current assembly.
