On the build tab in a Web Application project I have a setting called "Warning Level". I can set a value from 0 to 4. What do these values mean? Will a value of 0 be more strict and generate more warnings, or vice versa? I haven't been able to find any documentation on it yet, but perhaps I'm looking in the wrong place.
This link shows you the definitions of the warning levels (I'm assuming you are using C# code in your web project). Level 4 is the most strict.
