Market Data Feed not able Deserialize using asp.net c#

Hello,
I create asp.net Console App and using

var apiInstance = new WebsocketApi();
WebsocketAuthRedirectResponse result = apiInstance.GetMarketDataFeedAuthorize(apiVersion);
string URL = result.Data.AuthorizedRedirectUri;

and after establishment websocket connection I send Message

{"guid":"someguid","method":"sub","data":{"mode":"full","instrumentKeys":["NSE_INDEX|Nifty Bank","NSE_INDEX|Nifty 50"]}}

then OnMessage event when receives I get Data in hex format

but I am not able Deserialize or not able to convert in hex format into json string

Thank you for contacting us. You will have to use the protobuf to convert it to json. We currently lack a readily available example of .NET WebSocket (unlike Python, Node, PHP, and Java), We are working on it should be available soon. In the meantime, we suggest you briefly explore our existing example codes in other languages to see if you can correlate with your needs.

Hello I created a sample project please have a look.
