I have a custom module that has been built and added as a reference in my test cases project. They are both in debug mode, both have .pdb files in their assocaited \bin directories. Everytime I go to debug I get this message: "The following module was built either with optimizations enabled or without debug information: C:\WINDOWS\assembly\GAC_MSIL\Kailua\1.0.3.0_86d340ffca32cc5b\Kailua.dll To debug this module, change its project build configuration to Debug mode. To surpress this message, disable the 'Warn if no user code on launch' debugger action. " I am not able to step into code that is referenced by my test cases. Any suggestions are greatly appreciated. -- thanks - dave david_at_windward_dot_net http://www.windwardreports.com Cubicle Wars - http://www.windwardreports.com/film.htm
