Versioning

From version 1.4.0, BitcoinLib follows Semantic Versioning 2.0.0.

Building from source

To build BitcoinLib from source, you will need either the .NET Core SDK or Visual Studio.

Linux-specific

If you are using Linux you will also need Mono installed (in order to run Paket). The full install sequence (for Ubuntu) will be something like this.

Building & running tests

With Visual Studio you can build BitcoinLib and run the tests from inside the IDE, otherwise with the dotnet command-line tool you can execute:

dotnet build src/BitcoinLib.sln

The first time you run it, this will use Paket to restore all the packages, and then build the code.

Instructions for Bitcoin

• Locate your bitcoin.conf file (in Windows it's under: %AppData%\Roaming\Bitcoin, if it's not there just go ahead and create it) and add these lines:

  rpcuser = MyRpcUsername
  rpcpassword = MyRpcPassword
  server=1
  txindex=1
  

• Edit the app.config file in the Console test client to best fit your needs. Make sure you also update the bitcoin.conf file when you alter the Bitcoin_RpcUsername and Bitcoin_RpcPassword parameters.

Instructions for Litecoin and other Bitcoin clones

• Perform the same steps as those mentioned above for Bitcoin.
• Litecoin configuration file is: litecoin.conf under: %AppData%\Roaming\Litecoin and its daemon is: litecoind.
• Each coin can be initialized by its own interface specification:
  • IBitcoinService BitcoinService = new BitcoinService();
  • ILitecoinService LitecoinService = new LitecoinService();
• Any bitcoin clone can be adopted without any further installation steps with the use of the generic ICryptocoinService:
  • ICryptocoinService cryptocoinService = new CryptocoinService("daemonUrl", "rpcUsername", "rpcPassword", "walletPassword");
• Use (ICryptocoinService).Parameters to fully configure each coin pointer at run-time.

Configuration
