SpecFlow Visual Studio 2013 integration (v1.9.3) is released and available from the Visual Studio gallery!
The Visual Studio 2013 support can be installed from
Visual Studio Gallery or from the online search in Visual Studio / Tools / Extensions and Updates. (You have to search for "SpecFlow" :).
You can find more details at
http://www.specflow.org/documentation/Visual-Studio-2013-Integration/.
The Visual Studio 2013 support is provided as a different Visual
Studio Gallery package than the one for VS2010 and VS2012. This means
that this integration tracks the reviews and ratings separately from the
previous one.
Please help us and the other users by rating the package on the Visual Studio Gallery page!
