I am new to BDD and Specflow. I am using Specflow on Visual Studio 2013. Does Specflow supports all the supported languages by gherkin in the following json? https://github.com/cucumber/gherkin/blob/master/gherkin-languages.json
Short answer: yes
Long answer: We are supporting the languages, that are supported of the Gherkin Version we are using. Currently this is 4.0.0, so we are supporting the languages in https://github.com/cucumber/gherkin/blob/v4.0.0/gherkin-languages.json
Full disclose: I am one of the maintainers of SpecFlow.
