If you're really "new", I suggest you learn how to use C# to access REST API first.
https://docs.microsoft.com/en-us/aspnet/web-api/overview/older-versions/build-restful-apis-with-aspnet-web-api
(Or whatever the tutorial you feel comfortable with)

Once you get familiar with it, plug the RTC REST API calls into your application. They are not that different from any other HTTP requests. The sequence of calls that you use for a particular task is the same for all programming languages I suppose, while handling the HTTP requests and responses is different.

Thanks Ralph and Donald:-)
I guess the question was wrongly understood...the thing is, i am trying to get project name and its associated items by using the below.....but getting 403 forbidden error. so it would be better to provide the right URI will help me 

string _serverURL = https://localhost:9443/ccm; 
string _resourceURL = "https://localhost:9443/ccm/rootservices";
    
_resourceURL + "/oslc/contexts/_0_iN4G09EeGGMqpyZT5XdQ/workitems/order"
    
CookieContainer _cookies = new CookieContainer();//create cookie container
HttpWebRequest documentGet = (HttpWebRequest)WebRequest.Create(_resourceURL);
documentGet.Method = "GET"; //method
documentGet.CookieContainer = _cookies; //set container for HttpWebRequest 
documentGet.Accept = mediatype;
documentGet.Headers.Set("OSLC-Core-Version", "3.0"); //for RTC 3.0.1.2
documentGet.Timeout = 300000;
HttpWebResponse response = requestSecureDocument(documentGet, _serverURL, username, password);

Your _resourceURL variable contains an incorrect URL. Also, header "OSLC-Core-Version: 3.0" won't get you anywhere, as the current implemented OSLC version is 2.0.

I am not a C# guy, but I know our developers for the VisualStudio integration use HTTPS/REST calls. This question has also come up several times already.

If you are new to this, you should better read the results of the google query. 


I have nothing to share. My examples are all Java, but if you are interested, you can find them here: https://rsjazz.wordpress.com 

they won't help you of course.
