Lightstreamer unknown error using C# client

Hello,

I was able to get a demo working using the Lightstreamer quickstart C# example.

I am trying to integrate this demo with the Gain Capital streaming adapter.

I am working with Lightstreamer.DotNetStandard.Client (5.0.5) and I instantiated and populated a LightstreamerClient object so it looks like this:

The value I used for the password was the session token I got from https://ciapi.cityindex.com/TradingAPI/session (as the documentation states) and the User is the username that was given to me for the demo account.

When I try run the Connect() method on my LightstreamerClient object, this is what I get:

I can't find documentation for this error anywhere. Do you know what I am doing wrong?

Thanks in advance,

Ynor

Hi ynor,

it looks like that Gain Capital is using version 5.1.2 of Lightstreamer, as you can see here (expand Streaming API):
http://docs.labs.cityindex.com/#Getting%20Started/CIAPI%20Arky.htm%3FTocPath%3DGetting%2520Started%7C_____1

Therefor you must use a compatible .NET Client SDK:
https://www.lightstreamer.com/repo/distros/Lightstreamer_Allegro-Presto-Vivace_5_1_2_Colosseo_20140722.zip%23/Lightstreamer/CHANGELOG.HTML#dotnet_client

Please let us know if still experience any issue.

Best,
Gianluca
