The issue is that with VS 2017, now all extension who doesnt do async loading, are flagged as not responsive (that warning).

Also R# and VF# was flagged 😄 like i'd ever want to use F# without VF# or C# without R# 😆

Anyway, guide to conversion and more info is in https://docs.microsoft.com/en-us/visualstudio/extensibility/how-to-use-asyncpackage-to-load-vspackages-in-the-background#convert-an-existing-vspackage-to-asyncpackage

16 s is still a lot if it is correct.

That's pretty much the time used by all extensions to start up, 8+ seconds. And whole extension, so some parts are reused by others extensions because shared that message is only for the time the extension need to initialize.

But yes, fixing that will improve a bit the freeze/wait at VS startup but not while 14 sec in my experience with similar changes in other extensions (like github, r# etc), because while you can do some part in background others will need ui thread anyway by design (that's how VS extension acquire a lock for an action pratically)
