GetWorkItemsAsync fails when it retrieves 1800 workitems

Question

GetWorkItemsAsync fails when it retrieves 1800 workitems. Example:

int[] ids = (from WorkItem info in wlinks select info.Id).ToArray();
WorkItemTrackingHttpClient tfvcClient = _tfs.GetClient<WorkItemTrackingHttpClient>();
List<Microsoft.TeamFoundation.WorkItemTracking.WebApi.Models.WorkItem> dworkitems = tfvcClient.GetWorkItemsAsync(ids).Result;

If I pass array of Ids with 90 elements it works fine.

Is there any limit that it can get only n number of elements, how can we overcome this problem?

Any clear description you can provide to 'fails'? Any error? — yakobom, Dec 19 '17 at 08:16

Yes, there is a limitation of the URL length, it will get this exception once the URL length has been exceeded.

So, as a workaround you can limit your calls to a allowed range at a time (e.g. 200 ids at a time). Then call several times for the query.

Unfortunately you’ve hit a limitation of the URL length. Once the URL length has been exceeded, the server just gets the truncated version, so odds are high that the truncated work item id is not valid.

I recommend limiting your calls to 200 ids at a time.

Reference this thread for the limitation of the URL length: What is the maximum length of a URL in different browsers?

This similar thread for your reference: Is there any restriction for number of characters in TFS REST API?
