The ProGuide explains how to set up tests using MSTest, in which you supply the path to the ArcGIS libraries in the "AssemblyResolution" element of a runsettings file. I'm not clear how to achieve this end using XUnit. Has anyone done this and can you offer any guidance?
I've read stuff like this, but that and pretty much everything else I've found is a decade old so I'm not sure how useful it is.
