I'm trying to implement deserialisation for MessagePacks.
I currently have a working implementation when I run my app on android. However, when I run the app on iOS, I get the following exception on runtime when hitting the deserialisation method.
System.NotImplementedException: byref delegate

This is the method
public override Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)
{
var options =
MessagePackSerializerOptions.Standard.WithResolver(
CompositeResolver.Create(
GeneratedResolver.Instance,
StandardResolver.Instance
));
// Exception thrown here.
var obj = MessagePackSerializer.Deserialize(type, readStream, options);
return Task.FromResult(obj);
}
I'm precompiling my custom types as recommended MessagePack Compiler via MSBuild Task which is working like a charm for android.
Has anybody got a clue why this exception is being thrown or what it even means? I really appreciate any help you can provide.
