When you build an AppWizard-generated application that has a directory with a trailing backslash (\) specified in the Additional Include Directories field of the C/C++ Preprocessor settings, you receive this error:
   LINK : fatal error LNK1561: entry point must be defined
   Error executing cl.exe.


The backslash (\) character is interpreted as an escape character.


To work around this problem, do not include trailing backslashes in the Additional Include Directories field of the C/C++ Preprocessor settings. For example, specify directories as C:\Project\Inc rather than as C:\Project\Inc\. Or if you want to specify the current directory as .\, use just the period (.) instead.


Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.
