I assume this is a simple fix considering I don't see any other posts about others having this issue. I am using VS2012 and I added slowcheetah 2.5.10.3 to the project using the nuget package installer.
I have tried opening a new console application as well as a unit test project, but in both I am not able to "add transform" to my App.config. The option in the context menu doesn't exist...
You will need to install the SlowCheetah Visual Studio extension to get the additional menus in Visual Studio. The NuGet package only adds a .targets
file to the solution which is useful for command line (build server) scenarios.
