BitcoinLib is available on NuGet:

• BitcoinLib

From version 1.4.0, BitcoinLib follows Semantic Versioning 2.0.0.

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

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

• 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.

• 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.

Sample configuration:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings>
    <!-- BitcoinLib settings start -->

      <!-- Shared RPC settings start -->
      <add key="RpcRequestTimeoutInSeconds" value="10" />
      <!-- Shared RPC settings end -->

      <!-- Bitcoin settings start -->
      <add key="Bitcoin_DaemonUrl" value="http://localhost:8332" />
      <add key="Bitcoin_DaemonUrl_Testnet" value="http://localhost:18332" />
      <add key="Bitcoin_WalletPassword" value="MyWalletPassword" />
      <add key="Bitcoin_RpcUsername" value="MyRpcUsername" />
      <add key="Bitcoin_RpcPassword" value="MyRpcPassword" />
      <!-- Bitcoin settings end -->

    <!-- BitcoinLib settings end -->
  </appSettings>
</configuration>
