Can't RPC to Bitcoind (C# / Windows)
I do not understand why some samples use port 8332, some 8333, etc.


Port 8333 is the port that bitcoin uses to connect to other nodes on the network. Port 8332 is the default port for a bitcoin RPC interface. To connect with RPC, use port 8332 or specify a different port with rpcport=&lt;port&gt; option
