Code Inspections in VB.NET

In VB.NET, ReSharper 2018.1 provides two kinds of code inspections: 252 inspections that detect errors such as broken syntax, unresolved symbols, compiler errors, etc. (you cannot configure or disable any of these inspections), and 244 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 VB.NET 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
Inactive preprocessor branch InactivePreprocessorBranch resharper_inactive_preprocessor_branch_highlighting Warning

Common Practices and Code Improvements (107 inspections)

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

Redundancies in Code (22 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.
