XmlException: Unexpected DTD declaration. Line 1, position 3.

When I try to use below code to test the API search:

var context = new Context(Scheme.Https, "www.splunk.com", 443);
using (var service = new Service(context, new Namespace(user: "nobody", app: "search")))
{
    Run(service).Wait();
}

/// <summary>
/// Called when [search].
/// </summary>
/// <param name="service">The service.</param>
/// <returns></returns>
static async Task Run(Service service)
{
    await service.LogOnAsync("aaa", "bbb");

    //// Simple oneshot search
    using (SearchResultStream stream = await service.SearchOneShotAsync("search index=test_index | head 5"))
    {
        foreach (SearchResult result in stream)
        {
            Console.WriteLine(result);
        }
    }
}

But failed, get the error message:
XmlException: Unexpected DTD declaration. Line 1, position 3.

Question:
int this line: new Namespace(user: "nobody", app: "search")
how to define the "user" and "app" parameters value?

I try to use this way:
var service = new Service(new Uri("https://www.splunk.com"));
but still failed and got the same error message.

@jianzgao - I think you are using C# SDK for Splunk.

Splunk has made that SDK deprecated - https://github.com/splunk/splunk-sdk-csharp-pcl

I would recommend using either Python SDK (https://github.com/splunk/splunk-sdk-python ) or Java SDK (https://github.com/splunk/splunk-sdk-java ) or Javascript SDK (https://github.com/splunk/splunk-sdk-javascript )

I hope this helps!!!

@VatsalJagani Thank you for your quick reply.

But as a .net platform soft engine, I would like perfer to use the C# SDK. I feel so confuse why deprecate the C# SDK. 
We plan to use C# SDK of splunk to implement some new features. 
Seem like we have to change the solution. 

Thank you again.

@jianzgao - If you are just starting to work on a new solution, I won't recommend using C# as its been no changes to that for a long time. So you would have to end-up maintaining the library yourself, fixing all the issues similar to this one.

I have personally used Python SDK and its most widely used one if you are comfortable using it.

I hope this helps!!! Kindly upvote if this helps you!!!
