[feature request] Add run any byte code/dll in deserialization chain

[Chestnuts4]

in TextFormattingRunProperties chain, we can run any system command in deserialization vulunraibilitu, but sometime we want to run any byte code or dll in target, so do you think that feature should be added, if you do I would apply PR.

Hi, I think this has already been added here: https://github.com/pwntester/ysoserial.net/blob/master/ysoserial/Generators/XamlAssemblyLoadFromFileGenerator.cs

I am personally against having this as a separate gadget but more as a variant or a plugin. However, it is certainly a useful addition to have (you can basically call many functions with this as many do for example to deserialize another payload).

Please let us know if you meant something else other than this existing gadget.

I reviewed

https://github.com/pwntester/ysoserial.net/blob/master/ysoserial/Generators/XamlAssemblyLoadFromFileGenerator.cs#L104-L106

but when it call GetType method the <ObjectDataProvider.MethodParameters/> tag is not closed.

I haven't tried using this gadget yet, it just doesn't seem to work, I will try to use this gadget later
