Hi Scott,
If you installed the 64bit version of B1 Studio then I recommend you try uninstalling this and installing the 32bit version instead. I had problems getting the 64bit version to load properly as an addin in VS but the 32bit one works fine.
I can confirm that I've got VB and C# templates in patch 7 (you should see a separate SAP Business One section in the Visual C# and Visual Basic templates) so your patch 8 system should have both.
Kind Regards,
Owen
