Basic concepts
Authentication
The first lines in your .NET code should be used to create the Webservices object.
We suggest using this method:
OKMWebservices ws = OKMWebservicesFactory.newInstance(host, username, password);
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using com.openkm.sdk4csharp;
using com.openkm.sdk4csharp.exception;
namespace OKMRest
{
    public class Program
    {
        static void Main(string[] args)
        {
            String host = "http://localhost:8080/OpenKM";
            String username = "okmAdmin";
            String password = "admin";
            OKMWebservice ws = OKMWebservicesFactory.newInstance(host, username, password);
            try {
                System.Console.WriteLine(ws.getAppVersion().getVersion());
            } catch (RepositoryException e) {
                System.Console.WriteLine(e.ToString());
            } catch (DatabaseException e) {
                System.Console.WriteLine(e.ToString());
            } catch (UnknowException e) {
                System.Console.WriteLine(e.ToString());
            } catch (WebserviceException e) {
                System.Console.WriteLine(e.ToString());
            }
            System.Console.ReadKey();
        }
    }
}
Also is possible doing the same from each API class implementation.
We do not suggest this way.
For example with this method:
RepositoryImpl repositoryImpl = new RepositoryImpl(host, username, password);
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using com.openkm.sdk4csharp;
using com.openkm.sdk4csharp.exception;
using com.openkm.sdk4csharp.impl;
namespace OKMRest
{
    public class Program
    {
        static void Main(string[] args)
        {
            String host = "http://localhost:8080/OpenKM";
            String username = "okmAdmin";
            String password = "admin";
            RepositoryImpl repositoryImpl = new RepositoryImpl(host, username, password);
            
            try {
                System.Console.WriteLine(repositoryImpl.getAppVersion().getVersion());
            } catch (RepositoryException e) {
                System.Console.WriteLine(e.ToString());
            } catch (DatabaseException e) {
                System.Console.WriteLine(e.ToString());
            } catch (UnknowException e) {
                System.Console.WriteLine(e.ToString());
            } catch (WebserviceException e) {
                System.Console.WriteLine(e.ToString());
            }
            
            System.Console.ReadKey();
        }
    }
}
Accessing API
OpenKM API classes are under com.openkm package, as can shown at this javadoc API summary.
At main url http://docs.openkm.com/apidoc/ you'll see all available javadoc documentation.
At the moment of writing this page the actual OpenKM version was 6.3.0 what can change on time.
There is a direct correspondence between the classes and methods into, implemented at com.openkm.api packages and available from SDK for .NET.
