How to return TFS workitem fields in WIQL?

Question

I am trying to query workitem info from TFS - specifically from the CMMI Risk template. It looks like no matter what I put in the select clause, I still actually need to look in the Fields collection for the value. With this query:

WorkItemCollection queryResults = workItemStore.Query(@"
                                            SELECT [System.Id], 
                                                    [System.WorkItemType], 
                                                    [System.Title], 
                                                    [Microsoft.VSTS.Common.Severity],
                                                    [Microsoft.VSTS.CMMI.Probability]
                                            FROM WorkItems 
                                            WHERE [System.TeamProject] = 'MyProj' 
                                            and [System.WorkItemType] = 'Risk' 
                                            ORDER BY [System.Id] ");

I cannot see

 queryResults[0].Severity or
 queryResults[0].Probability

in the output, but I can see

queryResults[0].Fields["Severity"];

Seems the select list is irrelevant in this case. What am I missing?

Answer 1

Only for a few fields properties are created (I believe it are the system fields). For all other fields you need to access it as you described.

So you are not missing anything.
