In this page of ReSharper options, you can specify your preferences for code inspection.
Enable code analysis
Select this checkbox to enable design-time code inspection.
Regardless of this checkbox, you can always run code inspection in specific scope.
Read settings from editorconfig and project settings
If you use EditorConfig to maintain code styles for your project, you can also configure code inspections from .editorconfig files.
Enable solution-wide analysis
Note that in large solutions, solution-wide analysis may result in some performance degradation. However, there are several ways to improve the performance of solution-wide analysis.
Enable computationally expensive inspections
Turns on the data-flow analysis and brings additional inspections, for example, to calculate nullability.
Enables warnings in solution-wide analysis.
When warnings are enabled in solution-wide analysis, it works as follows: as long as there are errors in the solution, only errors will be displayed; unresolved warnings will only appear when the last error is fixed. When warnings are disabled, the status bar indicator will turn green as soon as the last error is fixed.
When this option is enabled, you can click on the toolbar of the Errors/Warnings in Solution window to show or hide warnings in the window and in the status bar indicator without restarting the analysis.
Show unused non-private type members when solution-wide analysis is off
When this option is enabled, ReSharper will detect all unused non-private members even if solution-wide analysis is disabled. This option does not have any significant performance impact on small- and medium-sized solutions.
However, you may want to disable it if you experience performance problems in a large solution or when working with very large source files.
Show unused global using directives when solution-wide analysis is off
When this option is enabled, ReSharper will report all
However, you may want to disable it if you experience performance problems in a large solution.
Value analysis mode
Using the value analysis, ReSharper finds out which entities can hold null value and highlights possible errors with null dereference. You can choose one of the following modes.
Nullable reference types' warnings mode
If nullable reference types (NRT) are enabled, ReSharper reuses the results of C# compiler analysis.
NRT improve overall precision of the nullability analysis, but there are cases when NRT contracts can be violated, for example, when values are coming from code without
For more information, refer to Nullable reference types.
Analyze integer arithmetic
Use this checkbox to enable or disable the analysis of integer values (integral arithmetics).
This option lets you enable or disable ReSharper syntax highlighting scheme.
If it is selected, language identifiers are highlighted with colors as defined in Visual Studio options:.
The list of syntax identifiers provided by ReSharper is available in the Display items list, each name starting with the ReSharper prefix.
Note that by disabling this option you also disable symbol information tooltips that appear on mouse over.
Highlight color usages
Enables highlighting of color definitions in code. For more information, refer to Color assistance.
Highlight special characters in string literals
Enables highlighting of correct and incorrect escape sequences in non-verbatim strings. For example:
For more information, refer to Regular expressions assistance.
Highlight captured primary parameters
When this option is enabled, ReSharper changes syntax highlighting of primary constructor parameters that are used in instance members. Such parameters become captured in the instance context and behave like instance fields, therefore it is convenient to have them syntactically highlighted as fields.
In the example below, the
Highlight usages of the element under the cursor
By default, when you set a caret at a declaration or a usage of a variable or a member, all other usages of that symbol in the file are displayed with a background highlighting. Use this checkbox to toggle this behavior.
Highlight context exits
This option, which is enabled by default, tells ReSharper to highlight all places where the control flow can exit the current context. For example, for a method, it will highlight the return type of the method, all
For a loop or a
Note that if a method is not entirely visible in the editor, you can invoke the Navigate To: Function Exits command on the method name to trigger another kind of highlighting, which will not disappear when your caret leaves the method name.
Highlight related async/await keywords
This option enables highlighting of all
Highlight condition elements
This option enables highlighting of matching logical and conditional operators (
In the example below, %product helps understand that the highlighted operators will be evaluated together, while the
