ReSharper 2020.2 Help


ReSharper | Options | Code Inspection | Settings

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.

If this checkbox is enabled, you can configure code inspection severity levels and C# naming styles right from .editorconfig files.

Enable solution-wide analysis

Enables Solution-Wide Analysis (including solution-wide code inspections), which is disabled by default.

Note that in large solutions, solution-wide analysis may result in some performance degradation. However, there are several ways to improve the performance of the solution-wide analysis.

Include warnings

Enables warnings in the Solution-Wide Analysis.

When warnings are enabled in the 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.

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 the 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 the 'Import namespace' action using popup If this option is selected, a popup that suggests importing namespaces in C# and VB.NET shows up if there is one or more non-imported types are detected in the file:
Namespace import quick-fix
If the checkbox is not selected, the corresponding action will be available in the action list on Alt+Enter.
Show missing constructs as editor hints

You can display missing returns in functions and missing breaks in switch statements using inlay hints. This lets you immediately understand what exactly is missing:

ReSharper Inlay hints: missing return
Show resources dispose points as editor hints

You can use inlay hints to see places where resource variables are disposed:

ReSharper Inlay hints: disposed resource variable
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.

  • Optimistic: when explicitly marked with [CanBeNull] attribute, or checked for null — ReSharper assumes that only entities explicitly marked with CanBeNull or ItemCanBeNull attribute or explicitly checked for being null, can be null.

  • Pessimistic: when entity doesn't have explicit [NotNull] attribute— ReSharper assumes that all nullable entities without an explicit NotNull or ItemNotNull attributes can be null.

Enable nullability analysis when C#8 compiler nullable warnings are enabled


Color identifiers 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: Tools | Options | Environment | Fonts and Colors.
The list of syntax identifiers provided by ReSharper is available in the Display items list, each name starting with ReSharper prefix.
Highlight color usages Enables highlighting of color definitions in code. For more information, see Color Assistance.
Highlight special characters in string literals Enables highlighting of correct and incorrect escape sequences in non-verbatim strings. For example:
Highlighting of escape sequence in strings
For more information, see Regular Expressions Assistance.
Highlight context exits This option, 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 return, throw keywords, and so on when you set the caret to one of these identifiers
ReSharper highlights context exits
For a loop, it will additionally highlight the loop keyword as well as all the break statements inside this loop.
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.
