@juanfranblanco Thankful for your awesome work. You really put effort in keeping things up-to-date. Many thanks.

I need help with a modern scenario that is increasingly becoming common - delegated proxy contracts.

I am creating a proxy contract using
My Registry contract implements the IRegistry, but has many other functions.

I need to know how to generate c# service code in this scenario?

@Vutov I cant use a struct state variable mapping implementation. Instead i need to return multiple variables via return from solidity function. how can i receive those values. I'm getting first value only .
I mean how can i receive a tuple in nethereum

@juanfranblanco Hi,how can i use Nethereum to add listener for block and contract change like web3.js
var account_one = web3.eth.accounts[0];
var account_two = web3.eth.accounts[1];

var account_one_balance =;
console.log("account one balance:", account_one_balance.toNumber());

var txhash = metacoin.sendCoin.sendTransaction(account_two, 100, { from: account_one });

var myEvent = metacoin.Transfer(); (err, result) {
if (!err) {
if (result.transactionHash == txhash) {
var account_one_balance =;
console.log("account one balance after sendCoin:", account_one_balance.toNumber());
} else {

// output:
account one balance: 7000
account one balance after sendCoin: 6900

@jyothishqburst It should work the same. Here is example of what I did - contract signature - public view returns(bool, string, string, uint), C# class -, how its called var getFunction = contract.GetFunction("getBetMetaInfo");
var resultget = await getFunction.CallDeserializingToObjectAsync<EventInfo>();

@knocte oh is not what you think, mainly it is a fully refactored version of the current code generator, but also to replace the javascript code generator of vscode. Once it is done it will be hopefully very easy to generate anything from an abi
and yes iOS AOT wont work :(
@triston_abhi_twitter you need the HD Wallet
check thew workbooks
@jyothishqburst check the FunctionOutput class and DeserliasingToObject method
oh it is have been answered thanks :)
@oldbaker so you want to generate a service based on a delegate proxy that calls another contract

or messages that do the same

@slqcyy check the events and filters

i use the : var transactionReceipt = await transactionPolling.SendRequestAsync(() =>
web3.TransactionManager.SendTransactionAsync(account.Address, addressTo, new HexBigInteger(1))
the transaction is OK , but it will have exception : unknown transaction
i use scan to search, the transaction is OK.
But the code will have exception.
