Not able to connect to QlikSense using C# code

vpraja03 — Sat, 16 Nov 2024 20:33:06 GMT

Hi,

I am using the below code to connect to QlikSense via C#

string url = "https://abc.test.com";

Uri uri = new Uri(url);

ILocation location = Qlik.Engine.Location.FromUri(new Uri(url));
location.AsNtlmUserViaProxy();

using (IHub hub = location.Hub())
{
Console.WriteLine(hub.EngineVersion().ComponentVersion);
}

while debugging, the command comes to using (IHub hub = location.Hub()) line, getting the below error.

Kindly help me to resolve it asap.
