Summary: This chapter shows you how to review code built using the .NET Framework for potential security vulnerabilities. It shows you the specific review questions to ask and discusses the tools that you should use. In addition to general coding considerations, the chapter includes review ...
You can have the Static Checker look for implicit as well as explicit contracts. An explicit contract is any contract you declare in a class method, such as a precondition, a postcondition or an invariant. In addition, the Static Checker can also take into account some built-in Code Contrac...

In the scope of calculations, many transformations on numeric type variables (addition, subtraction, multiplication, and so on) may cause the calculation to leave its defined range and silently wrap, leading to integer overflows or underflows. This becomes a problem when the...
These operators are used with numbers to perform basic math, for example “+” for addition. Computers have to add and subtract, multiply and divide to do almost anything. Array A single variable that contains a list of data. For example, myNumbers = [0,1,2,3]. Here, myNumbers is ...
