This appears to be caused by the dte.ActiveSolutionProjects array being empty. The workaround is to click on the project in Solution Explorer - then the array seems to get populated.

A better fix would be to replace the code in GetCurrentProject with logic similar to Thomas Levesque's answer in https://social.msdn.microsoft.com/Forums/vstudio/en-US/9816f4b5-cb16-457d-9e99-787ad6cb34cf/vs2010-t4-any-way-to-obtain-name-of-the-current-project?forum=vsx. I've tested this locally and it seems to do the trick.
Comments: This has been implemented, and will be in the next release. Thanks!
