c# - Creating a VSTO Add in for multible applications -

is possible create vsto add in multible office applications?

can outsource functions want have every application , create add-in every application? if yes, there better way achieve this?

i recommend making solution add-in project each office application.

then add class library project solution , reference each of add-on projects.

that way can centralize code used in add-ins.

if need interact active application or document, can detect type of calling object , typecast relevant application/document type.
