Regression - broken messages during gauge run

[tomzo]

Since I upgraded from older gauge and csharp plugin the messages are no longer meaningful during gauge run. It worked fine previously in gauge v0.4.0 and gauge-csharp around 0.8.0 which I have built from sources.

Problem is that all steps are replaced by Sandbox <Full name of step-implementing class>.

Actual behavior

E.g. This is the output I see for all steps in all features described:

Gauge.CSharp.Runner.SandboxBuilder Creating a Sandbox in: /ide/work/gauge-bin/
# Entropy
  ## Get entropy    Sandbox FunctionalStcRandom.Entropy
 ✔Sandbox FunctionalStcRandom.Entropy
 ✔Sandbox FunctionalStcRandom.Entropy
 ✔Sandbox FunctionalStcRandom.Entropy
 ✔

Expected behavior

I would expect step text from markdown to be in each tick.

Gauge version

Possible cause

It looks like some ToString() disappeared?
