Managing Null-Forgiving Operators

Sometimes it is necessary to use the null-forgiving operator "!" to suppress a false warning. However using too many of them will render the value of nullable checks almost useless. Also since the analyzer will suppress many common false positives, plenty of the null forgiving operators may be obsolete after installing the analyzer.

Since it's hard to find the null forgiving operators in code, this Visual Studio Extension lists all occurrences, categorizes them, and even detects those that are still present in code but no longer needed.

Occurrences are grouped into three categories, to reflect their different contexts:

• General usages of the null-forgiving operator.
• Null-forgiving operator on the null or default literals.
• Null-forgiving operator inside lambda expressions.

e.g. general usages can be mostly avoided by cleaning up the code, while inside lambda expressions they are often unavoidable
