Task Recorder should record file upload so that Pref SDK should be able to use the Developer XML, and it must be able to generate the C# performance test on it. Currently, the test will fail if your test has the excel file uploaded in between any process. Just like in my case I was using transfer orders and its recording failed after importing as a C-sharp test because no file uploaded was captured by the task recorder.

Hope this will be a very nice feature.
