yes, we still have the issue.
I think have installed Visual Assist a few years ago, but not with Visual Studio 2015 and not currently.
I would create the dummy sample as soon as possible and give you a response.
I think the normal usage is to open the sln per double click in Explorer and then until work is finished, closing this VS instance.Do users perform the Open from Source Control (or Open from Vault) action more than once on a solution? Once something is bound, you then use either the shortcuts for recent solutions or open the .sln from disk instead of another Open from Source Control.
