There is a sticky VSX FAQ post in the Visual Studio Extensibility (VSX) Forum since more than one year ago that is intended to collect the FAQs about development of Visual Studio extensions (packages, add-ins, templates, isolated shell, etc.). Unfortunately there aren’t many FAQ entries in each category, which is a pity. Today I have added tons of them in the “Add-ins” category, my area of expertise, pointing to the most useful HOWTO articles of my MZTools Articles Series. Hopefully they are useful for people before posting in the forum:
