Question: I am having problem after new Resharper 8.2 update that in String.Format method if I have arguements then the argement list is not getting hilighted and context action like "remove item from at index" is not showing when I selet the argment. Everthing was workign fine before, I have not seen any bug reported on Resharper regarding that. I have tried to restart computer and visual studio but with not success. Is anyone had the same problem? I am using visual studio 2008.

Answer: 
I know this thread is old, but I'll answer it anyway, in case someone encounters the same problem. To be able to edit a test case, you should call Open() like this:

```
theCase.WorkItem.Open();

```

And that's it.
You should just call a WorkItem. That's enough if you 

```
 testCase.WorkItem.PartialOpen();

```

if you call

```
 testCase.WorkItem.Open();

```

then Save, you will to override the steps and parameter value
