If anyone wants to have a go developing something with c#, I've written an api library that can use any nis safely. You don't even need to set up the connection if it doesn't matter what node you connect to, it auto connects to trusted Dev nodes, all you gota do is not pass a connection to Accountfactory and the connection will set itself up. Its also a single line job to bounce between test net and main net.

For now I would advise only using on testnet until I update the fee structure and do a few other things, I just don't have time atm. Should have it done soon tho.

I tried to make it as simple to use as possible so once the library is imported you can literally copy paste the code in the read me into your project and it will work.

Plz send a small ammount. I know it's unfair because you're not the fraudster (or so it seems) but we'll need to make sure only the right people get stakes

You are marked with duplicate hash. This means theit either you used someone elses hash or your hash was used by someone else.

You'll need to prove that you own the address that the payment came from. You can do that by sending another very small amount from the same address.
Plz also provide a link to your original post.
