Add a reference to TechTalk.SpecFlow and then put this in an App.config file of the MSTest project:
<?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="specFlow" type="TechTalk.SpecFlow.Configuration.ConfigurationSectionHandler, TechTalk.SpecFlow"/> </configSections> <specFlow> <unitTestProvider name="MsTest" /> </specFlow> </configuration>
