Code Inspections in ASP.NET

Last modified: 21 July 2022

In ASP.NET, ReSharper 2022.1 provides two kinds of code inspections: 6 inspections that detect errors such as broken syntax, unresolved symbols, compiler errors, and so on (you cannot configure or disable any of these inspections), and 35 proprietary code inspections, any of which you can disable or change its severity level.
These code inspections help you detect code issues in design time in all open files, and additionally they allow you to find code issues in specific scope.

Configurable ASP.NET inspections are listed below, grouped by their categories.

Common Practices and Code Improvements (1 inspection)

This category groups inspections that hunt for medium severity issues that mainly affect code readability.

Redundancies in Code (3 inspections)

Code inspections in this category look for redundancies and dead code, which affect code readability and style, and could be safely removed. Some code redundancies cannot be fixed automatically, and quick-fixes for them are performed in the interactive mode, requiring the user input. But the majority of the redundancies can be fixed without user interaction, using either fix in scope or code cleanup.
