Visual Assist build 2116 introduces preliminary support for Visual Studio 2017 RC.
Testing of Visual Assist with Visual Studio 2017 RC is ongoing.
The Visual Assist suggestion and completion listbox features are available in VS2017RC, however they are not complete. Development is continuing.
The Visual Assist .exe installer erroneously reports an install failure when using a localized (non-English) version of Visual Studio 2017. This will be fixed in the next release of Visual Assist. [Fixed in VA build 2118.]
Folder-based solutions aren't working quite as well in the RC than in earlier Preview releases. The system include paths aren't being populated properly. After you open a folder, check to see if the "stable include files" list on the C/C++ Directories page of the VA Options dialog is reasonable. You may have to switch Platform from Win32 to Custom and manually add system include paths to the list. [The situation has improved in the post-RC update of VS2017; unrelated to that update, folder-based solutions will see improved support in the next VA release.]
