Nullable Extended
A Visual Studio extension that lists all usages of the null-forgiving operator ! in your solution, categorizes them, and detects those that are still present in code but no longer needed.
Usage
Start the tool window from the tools menu:
The tool window shows all occurrences of the null-forgiving operator in your solution and their justification comments. It also shows if the null-forgiving operator is required to suppress nullable warnings. If the "Required" column is not checked, the null-forgiving operator might be obsolete and can probably be removed.
- Click the refresh button to scan your solution.
- Double click any entry to navigate to the corresponding source code.
Justification comments
A justification comment is one or more single line comments directly above the statement or declaration. The first comment line must start with // !, followed by the justification text:
// ! This is only needed to demo the feature
var text = value1!.ToString();
Occurrences are categorized like the analyzer does:
| Id | Context |
|---|---|
| NX0001 | Any other usage of the null-forgiving operator. |
| NX0002 | Null-forgiving operator on the null or default literals at any other statement. |
| NX0003 | Null-forgiving operator inside lambda expressions. |
| NX0004 | Null-forgiving operator on the null or default literals at init only property assignment. |
