Which version of Gallio are you using? (I have hardcoded the plugin to link to Gallio.dll 3.4.11.0)
You need the following files in the plugin folder:
- Gallio.ReSharperRunner71.dll
- Gallio.ReSharperRunner71.plugin
- Gallio.dll
- Gallio.XmlSerializers.dll (Not sure if this one is required..)
Does that help?
