We deployed an private Ethereum blockchain with Azure Template "Proof of Work" and while we try to login in to blockchain via web3 from visual studio c# code, we face the following issue “The method personal_unlockAccount does not exist/is not available” and while we try to unlock the web3 API account from PowerShell using the script "geth --rpcapi eth,web3,personal --rpc" we receive the following error “Maximum peer count ETH=25 LES=0 total=25 Fatal: Error starting protocol stack: datadir already used by another process

C# Code used to unlock account is as follows

  var web3 = new Web3(<<ETHEREUM-RPC-ENDPOINT >>);
            Task<bool> unlockAccountResult =
                 web3.Personal.UnlockAccount.SendRequestAsync(senderAddress, password, 120);

            bool s = unlockAccountResult.Result;

Note : We are able to test the contract in development environment without any issues on "Ganache".

Any Quick insights on this will be appreciated. Thanks in advance.

Take a look at this github discussion: https://github.com/Nethereum/Nethereum/issues/105. It seems to have a solution for your problem.
