1. Open the attached project.

2. Add a breakpoint in line 9 (Repro.cs), attach, click 'Test\Launch Repro' in menu bar.

3. Try Evaluating CallMe(string) with any value in the watch tab, notice the 'Incorrect number or type' error, works fine on int or with no args.

4. Seems to be an issue with Unity rather MD itself, because this works when debugger is not attached to the editor. Static functions with string args can be evaluated while in debugger in a console app with Unity's version of MD, also works on MD 3.0.6.
