<div dir="rtl"><div dir="ltr">Mixing Visual C++ 2012 and 2013 runtime DLLs should not a problem as long you don't try to allocate a resource (FILE, memory,...) managed by one runtime DLL and access or release it in other runtime DLL that does not know about it. In general the runtime DLLs don't coordinate resource management, unless the resource is actually managed by Windows behind the scenes. See here:</div>

Is there any sort of runtime incompatibility that would happen if we built with 2013, needed the 2013 CRT, but tried to run inside the VS2012 process? That would be a complete show stopper for us since we have a committed schedule for support of versions of VS that we host in.</blockquote>
