Possible bug - BadImageFormatException #10

I don't have good repro on this because it was reported on AppCenter, but here's the callstack:

This was on Android using Topten.RichTextKit v0.1.118

I do realize this is somewhat of an old version, and we may upgrade just to be safe, but I also wanted to bring this up in case it wasn't a known issue.

Thanks for reporting. I've not tried RichTextKit on Android so I'm not really sure, but this sounds more like an issue with the HarfBuzzSharp installation. I'm guessing the wrong version of libHarfBuzSharp.so and so it's just not loading it. I see similar exceptions on Windows when running x64 edition but the x86 .dll file is there.

I recommend reporting this to the HarfBuzzSharp devs.
