However, the use of exceptions can also be error prone, leading to new programming errors and code that is hard to understand. This paper describes ways to tame the ex- ception usage in C#. In particula r, the paper describes the treatment of exceptions in Spec#, an experimental superset of C# that includes code contracts. r, the paper describes the treatment of exceptions in Spec#, an experimental superset of C# that includes code contracts.
