I had a problem with version 1.0.6 where adding an SPA module to an existing solution that contained an MVC module did not add the project to the existing solution. Need to verify the _addProjectToSolution call is working correctly for the SPA project.
This actually isnt a bug. You have to say YES to overwrite the SLN file when yeoman asks. I have updated the FAQ section for the project site to include this question and some instructions.
