  "Quick error detection utility"

  by Muhammad on Nov 2, 2011 1:55 AM

  Summary:
  I've used this utility and found it helpful while debugging my small C++ programs. I found some problems while debugging the DLL with size larger than 20mb and therefore I divided the code and made several DLLs of around 2MB. Though its good for small applications. Microsoft has also provided comprehensive documentation for this tool.

  "Not a stand-alone, but good stuff."

  by jowen on Aug 30, 2011 7:13 PM

  Summary:
  Prefast is a great tool, and I use it in conjunction with FxCop. Prefast is great for PC-based apps. FxCop is better for stuff that we put on the corporate intranet. The kinds of switches that we use through Prefast are pretty much self-explanatory, so it doesn’t take much for me to check the code.
