AB1050 Invalid TOTP while connect.GenerateSession

I have revamped c# sdk version and have uploaded it to below link. This version works with totp. Here is the link :https://github.com/piyush-r-pub/SmartAPI_AO. How to use it: https://github.com/piyush-r-pub/SmartAPI_AO/wiki. Please let me know if you face any issues or need any help.

You are supposed to use any OTP library.

Do you have the QR code for TOTP?
Add OTPNet nuget in your project. (OTPNet)
Convert TOTP QR to OTP string.

//Initialize Samart API using clientcode and password to test the code.
string totp = "2EYUVJNXYERUXPLAATDRTUHSWM";
string Client_code = "DELL2456"; //YOUR CLIENT CODE
string Password = "3456"; //YOUR PASSWORD
string api_key = "OvPZUMMM";
string JWTToken = ""; // optional
string RefreshToken = ""; // optional

SmartApi connect = new SmartApi(api_key, JWTToken, RefreshToken);
OutputBaseClass obj = new OutputBaseClass();

//Login by client code and password
obj = connect.GenerateSession(Client_code, Password, totp);

------Next in SmartConnetClass
/User Calls/
public OutputBaseClass GenerateSession(string clientcode, string password, string totpString)
{
OutputBaseClass res = new OutputBaseClass();
byte[] secretBytes = Base32Encoding.ToBytes(totpString);

 **// Create an instance of the TOTP class
 var totp = new Totp(secretBytes);

 // Get the current TOTP code
 string totpCode = totp.ComputeTotp();**
 res.status = true;
 res.http_code = "200";
 try
 {
     AngelTokenResponse agr = new AngelTokenResponse();

     string URL = APIURL + "/rest/auth/angelbroking/user/v1/loginByPassword";

     string PostData = "{\"clientcode\":\"" + clientcode + "\",\"password\":\"" + password + "\",\"totp\":\"" + **totpCode** + "\"}";

If required, let me know, I can push entire code to GitHub

I too have the same problem. Somewhere in the forum for another similar issue someone has responded to get updated Angel One DLLs ... the github libraries are all 2 years old. Where can I find the latest DLLs that support TOTP usage
