• Visual C++ why are the NCB files so large in VC++ 2005?

  Hello, I am really puzzled about the NCB store in Visual Studio 2005. I understand that some improvements have been made to the IntelliSense, but the size of NCB files in really huge.

For instance, an NCB file of 50KB under VS 2003 now has 500-600 KB, a 200 KB NCB under VS 2003 now has about 2 MB. And NCB files that used ...Show All
