Visual Studio 2017
Visual Assist is not fully compatible with EditorConfig for C++ files. If you use EditorConfig in Visual Studio 2017 and the feature attempts to service a C++ file that Visual Assist opens, Visual Studio may enter a deadlock state. Example features in Visual Assist that open files, hence might instigate a deadlock, include Create Declaration, Create Definition, and Rename.
If you experience a deadlock, remove your EditorConfig files from the visibility of Visual Studio, refrain from using the offending feature in Visual Assist, or open all files the feature needs before invoking it.
Update 2017.09.20: This is anticipated to be addressed in Visual Studio 2017 version 15.5.
