VS is caching a lot of things, because it's slow, so it tries to overcome the slowness with caching, which causes even more problems.
Use CodeBlocks and MinGW, and problem is solved, and you also create more cross-platform code, so less time lost on porting to iPhone and Android and Linux.
VS is the worst C++ compiler in the world, MinGW is faster by 25%, and Intel C++ is faster by 47%. Just stop using VS and you have a better life, and your customers too.
Same with SharePoint btw, totally horrible how slow it is because of C# garbage collection, and how you need to spam a SharePoint server every minute with a wakeup webservice. Apache does not have any of those problems, it just works.
