Recent changes to Rally C# REST API? - rally

Question

1) Earlier this week I was able to create defects and testcases using the Create method, which took 2 arguments at the time (a string and the DynamicJsonObject). However now, it needs three. I understand that one of these is now the workspace reference. How do I go about getting the workspace reference? For creating defects and testcases, I am using an empty string, and this seems to be working correctly for me. Is this to be expected?
2) For creating test case results, I am having a bit of trouble.
DynamicJsonObject newTCResult = new DynamicJsonObject();
newTCResult["Date"] = DateTime.Now.ToString("yyyyMMdd");
newTCResult["TestCase"] = "/testcase/11271454106";
newTCResult["Notes"] = "test";
newTCResult["Build"] = "13.1.0.90";
newTCResult["Verdict"] = "Pass";
CreateResult cr = restApi.Create(" ", "TestCaseResult", newTCResult);
As of right now, absolutely nothing is happening when I run this. I was able to do this successfully earlier this week (when I was able to use the Create method with two arguments). I feel that the problem is because I don't have a valid workspace reference. I followed the suggestion of another user in a similar question prior to this which worked for earlier, however now I am having this problem.

Answer 1

I was finally able to resolve this. It appears that the date field needs to be converted to UTC, so my code now looks something like this
newTCResult["Date"] = DateTime.UtcNow.ToString("o");
After making that small change results were working correctly.

Answer 2

It's somewhat surprising that Creates on Stories or Defects work with an empty string for a Workspace ref, although I suspect that on the server-side, the Webservices API is just using Default Workspace for the User of concern.
Either way, here's how you can get a ref to the Workspace of interest:
String myWorkspaceName = "My Workspace";
// Get a Reference to Target Workspace
Request workspaceRequest = new Request("workspace");
workspaceRequest.Fetch = new List<string>()
{
"Name",
"ObjectID"
};
workspaceRequest.Query = new Query("Name", Query.Operator.Equals, myWorkspaceName);
QueryResult workspaceQueryResults = restApi.Query(workspaceRequest);
var targetWorkspace = workspaceQueryResults.Results.First();
Console.WriteLine("Found Target Workspace: " + targetWorkspace["Name"]);
String workspaceRef = targetWorkspace["_ref"];
You can then use workspaceRef in your call to restApi.Create().
