I'm sorry, but I just got extremely busy with school and real life things. Also, I tried it several times, but my implementation seems to work. The bug is probably caused by the newly-released Monero daemon binaries whose changes are not yet available on the official dev branch. Once everything gets merged, Monero Client .NET will probably work fine again.
Like I said, I have the problem even with 0.38.2. I think it has been having this problem since the beginning. I'd look at the code myself, but I've got to focus on other things this week. I'll have to try to compile it myself and debug it on my system when I get the chance.
