First we want to install ServiceStackVS Visual Studio extension. The easiest way to do this is to look for it from within Visual Studio by going to Tools->Extensions and Updates and searching the Visual Studio Gallery as seen below.
Optionally it can be downloaded and installed from the VS.NET Gallery
ServiceStackVS supports both VS.NET 2012-2015.
Alternatively if continuing to use an older version of the NuGet Package Manager you will need to click on Enable NuGet Package Restore after creating a new project to ensure its NuGet dependencies are installed.
