Microsoft announced today the Preview 5 release of Visual Studio “15”. The Visual C++ Project Engine changed between Preview 4 and 5, and the change prevents Visual Assist from loading solutions. The developers at Whole Tomato Software are working on a resolution.
If you use Visual Assist in Visual Studio “15”, stay with the Preview you have or update and wait for our next build. The next build of Visual Assist will add support for Preview 5 and nothing else.
Stay tuned to the usual channels.
