Code Inspections in C#

In C#, ReSharper 2018.1 provides two kinds of code inspections: 694 inspections that detect errors such as broken syntax, unresolved symbols, compiler errors, etc. (you cannot configure or disable any of these inspections), and 548 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 C# inspections are listed below, grouped by their categories.

Code Notification (1 inspection)

This category groups code inspections with minor severity levels.
Inspection ID EditorConfig property Default severity
Method invocation is skipped InvocationIsSkipped resharper_invocation_is_skipped_highlighting Hint

Code Style (36 inspections)

Inspections in this category detect violations of code syntax styles. In contrast to most of other code inspections, these inspections can either detect the same code construct as a code issue or not depending on the corresponding code style rule configured on the Code Editing | [Language] | Code Style page of ReSharper options. You can also fix issues that these inspection detect, using code cleanup.

Redundancies in Code (62 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.
