Description 

Debug/Release  

Indicates the current set of project options. By default, the distributed Debug and Release option sets have settings appropriate for debugging and deploying an application, respectively. The option sets provide an easy way to change project options based on your development activity. To create a user-defined option set, use the Save as button.  

Save as  

Displays a dialog box for naming and saving a user-defined set of project options.  

Delete  

Deletes the current option set. Only user-defined option sets can be deleted. The distributed Debug and Release option sets can not be deleted.  

Debug information  

Causes the compiler to generate debugging information and place it in a program database file (.pdb) the next time you run the application.
Corresponds to /debug.  

Optimization  

Enables optimizations performed by the compiler to make your output file smaller, faster, and more efficient. This option also tells the common language runtime to optimize code at runtime.
Corresponds to /optimize.  

Treat warnings as errors  

Treats all warnings as errors. Any messages that would ordinarily be reported as warnings are instead reported as errors, and the build process is halted (no output files are built).
Corresponds to /warnaserror.  

Show warnings  

Generates compiler warnings.
Corresponds to /nowarn.  

Conditional Defines  

Enter symbols referenced in conditional compiler directives. Separate multiple symbols with semicolons.  

Output Directory  

Specifies where the compiler will put the executable file.
Corresponds to /out.
