“Addins are an old technology that we are advising customers to move away
from. We expect to remove this from the product in a future version.”
Macros were gone in Visual Studio 2012, and it seems that add-ins will be gone in “a future version”. Coincidentally, Visual Studio 2013 has been announced today (you can read the announcement in Brian Harry’s blog and Somasegar’s blog). Now the intriguing question is for those of us with a heavy investment in add-ins such as MZ-Tools is: will VS 2013 support add-ins or will we be forced to migrate to packages (SDK)?
