Want to fetch feature details based on Feature title for workitem type feature in Azure DevOps using C#

Question

I am trying to develop a console application to fetch the workitem details for workitem type Feature in Azure DevOps.

I am using these Nuget package for my code:

Microsoft.TeamFoundation.WorkItemTracking.WebApi;

First, you have to connect to the service wit PAT and get the work item client:

VssConnection connection = new VssConnection(new Uri(ServiceURL), new VssBasicCredential(string.Empty, PAT));
WitClient = connection.GetClient<WorkItemTrackingHttpClient>();

If you know a work item id, you can get a work item and find all its fields in the Fields dictionary:

var wi = WitClient.GetWorkItemAsync(Id).Result;
foreach (var fieldName in wi.Fields.Keys)
Console.WriteLine(“{0,-40}: {1}”, fieldName, wi.Fields[fieldName].ToString());

If you try to find a work item through the title contents, you can use the wiql query:

string queryWiqlList = @"SELECT [System.Id] FROM WorkItems WHERE [System.TeamProject] = 'TEAM_PROJECT_NAME' and [System.Title] Contains '<YOUR SEARCH_TEXT>' and [System.State] <> 'Removed' and [System.State] <> 'Closed'";

Wiql wiql = new Wiql();
wiql.Query = wiqlStr;
WorkItemQueryResult result = WitClient.QueryByWiqlAsync(wiql).Result;

if (result != null)
{
    if (result.WorkItems != null) // this is Flat List 
        foreach (var wiRef in result.WorkItems)
        {
            var wi = WitClient.GetWorkItemAsync(wiRef.Id).Result;
            Console.WriteLine(String.Format("{0} - {1}", wi.Id, wi.Fields["System.Title"].ToString()));
        }
}
