I have a requirement which updates shared step results in MTM. I know there is a API CreateSharedStepResult from CreateSharedStepResult Microsoft.TeamFoundation.TestManagement.Client.ISharedStepResult, but this does not work.
I am able to update normal step details using CreateIteration,CreateStepResult. but i am not able to use CreateSharedStepResult in the same way.
Did you ever get the solution to this? We recently migrated from QTP to TFS MTM, and I am building a framework. I have the very same issue that you have stated. I cannot get a shared step result using CreateSharedStepResult(int,int).
If you could post the solution that would be really helpful.
