How to stay on the distribution with MonoTorrent?

Question

.NET

Hello. From here I took the sources of the torrent client using the monotorrent library.
It downloads files, provided that at the time the program was launched there were peers distributing these files.
If they were not there, then nothing will be downloaded, even if they appear later. This is one of the problems.
More exciting is the other - at the end of the file download, the client does not distribute them. Distributes only if at the time of downloading the files the same client was launched and it did not have missing files.
Is anyone familiar with this library? Maybe someone has a code or advice where to dig?
Or maybe there are alternative libraries for c#?
