Code Inspections in XAML

In XAML, JetBrains Rider 2018.2 provides two kinds of code inspections: 18 inspections that detect errors such as broken syntax, unresolved symbols, compiler errors, etc. (you cannot configure or disable any of these inspections), and 51 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 XAML inspections are listed below, grouped by their categories.

Code Notification (14 inspections)

This category groups code inspections with minor severity levels.

Common Practices and Code Improvements (3 inspections)

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

Compiler Warnings (2 inspections)

Inspections in this category detect compiler warnings before you compile.

Use of obsolete type or type member (error) ObsoleteElementError resharper_obsolete_element_error_highlighting Error

Constraints Violations (1 inspection)

This category includes code inspections, mostly with the warning severity level, which detect violations related to symbol attributes, including JetBrains Rider's code annotations, and other similar issues.
Inspection ID EditorConfig property Default severity
Inconsistent Naming InconsistentNaming resharper_inconsistent_naming_highlighting Warning

Potential Code Quality Issues (14 inspections)

This category includes inspections that detect critical issues (code smells), mostly with Error or Warning level. This category also includes inspections that ensure localization assistance.

x:Key is allowed for resources and dictionary elements only Xaml.XKeyAttributeDisallowed resharper_xaml_x_key_attribute_disallowed_highlighting Error
XAML language level error Xaml.LanguageLevel resharper_xaml_language_level_highlighting Error

Redundancies in Code (11 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.
