tfs2012 - Chutzpah throws exception in TFS Build: 'executor://chutzpah-js/': Method not found: 'System.String .. get_SolutionDirectory()' -

this exception:

an exception occurred while invoking executor 'executor://chutzpah-js/': method not found: 'system.string microsoft.visualstudio.testplatform.objectmodel.adapter.iruncontext.get_solutiondirectory()'

everything else fine , unit tests reported succeeded when build complete => build should succeeded

but due exception, build considered partially succeeded confusing.

i have been searching internet, still cannot find answer. please me, thanks.

this looks issue when deploy vsix package depends on vs2013 version of iruncontext , try run in vs2012. particular property not available in older version , exception.
