Configure code inspection settings

1. Select ReSharper | Options from the main menu or press Alt+R O, then choose Code Inspection | Settings on the left.

2. Use the Enable code analysis checkbox to toggle the design-time code inspection.

3. Optionally, you can enable or disable design-time inspection features on this page:

   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 the ReSharper prefix. Note that by disabling this option you also disable symbol information tooltips that appear on mouse over. note This option does not affect C++. To toggle syntax highlighting in C++, use the corresponding option on the Code Editing | C++ | Inspections page of ReSharper options .
   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: For more information, see Regular expressions assistance.
   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 return, throw keywords, and so on when you set the caret to one of these identifiers 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.
   Highlight related async/await keywords	This option enables highlighting of all async and await keywords in a function when your caret is on one of them. note Newer versions of Visual Studio provide the same functionality, so it can still work even if you disable this option.
   Highlight condition elements	This option enables highlighting of matching logical and conditional operators (|, ||, &, &&, as well as ? and ? pairs) that work together in a complex expressions when your caret is at one of such operators. In the example below, %product helps understand that the highlighted operators will be evaluated together, while the value1 > 1 || value2 >= 2 && condition1 part will be evaluated before, and the || value6 %lt; value7 || condition2 part will be evaluated after, according to the operator precedence.

4. If necessary, you can select the Enable solution-wide analysis checkbox to enable the Solution-wide analysis.

5. Click Save in the Options dialog to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer using the Save To list. For more information, see manage and share resharper settings.

Exclude specific files and folders from code inspection

1. Select ReSharper | Options from the main menu or press Alt+R O, then choose Code Inspection | Ignored Code on the left.

2. In the left part of the Elements to skip section, you can specify files or folders to be ignored by the code inspection.

3. In the right part of this section, you can specify masks (for example *.vb) that will exclude all matching files in the solution from code inspection.

4. Click Save in the Options dialog to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer using the Save To list. For more information, see manage and share resharper settings.

Exclude/include current file from/to code inspection

• Press Ctrl+Alt+Shift+8.

• Right-click the status indicator and choose Pause/Resume analysis.

Specify files and regions with generated code

1. On the Code Inspection | Generated Code page of ReSharper options (Alt+R, O), use the Add File and the Add Folder buttons to specify files or folders that contain generated code.

2. In the lower left part of the page, use the Add button to specify masks (for example *.Designer.cs) for generated code files.

3. In the lower right part of the page, use the Add button to specify names of the regions that contain generated code.

4. Click Save in the Options dialog to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer using the Save To list. For more information, see manage and share resharper settings.

Change inspection severity from the editor

1. Set the caret to a code issue highlighted by a ReSharper's inspection.

2. Press Alt+Enter or click the action indicator to the left of the caret to open the action list.

3. In the action list, choose Inspection [name of inspection] | Configure inspection severity and then select a new severity level:

   

4. Your change will be saved using the smart save logic.

5. If you need to save the modified severity level in a shared settings layer, click the Configure inspection severity menu item or press Enter when it is selected. In the dialog that appears, choose the desired severity level, click Save To and then choose the desired settings layer.

   

Modify severity levels of code inspections from options

1. On the Code Inspection | Inspection Severity page of ReSharper options (Alt+R, O), you can view all configurable code inspections and their severity levels. The inspections are grouped by languages and then by categories.

2. Find and select the inspection whose severity you want to modify. To find an inspection, just start typing its name.

3. Click the list to the right of the selected entry, and choose a desired severity level:

   

4. If the default severity level of an inspection is changed, you will see the Reset to default button next to it, which allows you to reset the severity to its default value.

5. Click Save in the Options dialog to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer using the Save To list. For more information, see manage and share resharper settings.

Suppress code inspection in specific scope

1. Set the caret to a code issue highlighted by a ReSharper's inspection.

2. Press Alt+Enter or click the action indicator to the left of the caret to open the action list.

3. In the action list, choose one of the following:

   • Inspection [name of inspection] | Disable once with comment — this option inserts a single comment ReSharper disable once [inspection id], which only suppresses the inspection for the first occurrence of the corresponding issue.

   • Inspection [name of inspection] | Disable once with comment | Disable in file with comment — this option inserts a single comment - ReSharper disable [inspection id] in the beginning of the file. This comment suppresses the inspection for all corresponding issues in the file.

   • Inspection [name of inspection] | Disable once with comment | Disable and restore with comment — this option inserts a pair of comments before and after the issue - ReSharper disable [inspection id] and ReSharper restore [inspection id]. These comments suppress the inspection for all corresponding issues between them.

     You can then move these comments to other places in the file so that several issues of this type are suppressed. For example, this can be useful to suppress the 'redundant namespace' inspection if you want to keep several unused namespace imports.

   • Inspection [name of inspection] | Disable once with comment | Disable for method — this option adds the following attribute to the method: [SuppressMessage("ReSharper", "[inspection id]")]. This attribute suppresses the inspection in the method.

   • Inspection [name of inspection] | Disable once with comment | Disable for class — this option adds the following attribute to the class: [SuppressMessage("ReSharper", "[inspection id]")]. This attribute suppresses the inspection in the whole class.

   • Inspection [name of inspection] | Disable once with comment | Disable all inspection in file — this option inserts a single comment ReSharper disable All in the beginning of the file. This comment suppresses all inspections in the file.

     If necessary, you can insert the ReSharper restore All to enable code inspections after a specific line.
