Localization Inspections and quick-fixes
ReSharper provides a number of code inspections that help you localize your application by detecting localizable strings, problems with resources etc. in resource files and resource usages in code files. These inspections detect localization issues in design time in the open documents and allow you to find localization issues in specific scope up to the entire solution.
In design time, detected issues are highlighted to draw your attention. To resolve the highlighted issues, ReSharper provides a number of resource-specific quick-fixes.
Configuring localization inspection
By default, localization inspections are enabled in a project if the project contains at least one resource file.
One way of adjusting localization inspection is to change severity of specific inspections. You can find localization inspections (e.g. Element is localizable) in the Potential Code Quality Issues category on the page of ReSharper options.
You can also configure localization inspections per project.
To configure localization inspection in project
Right-click on the project in the Solution Explorer and select Edit project item properties from the context menu.
Select the desired value in the Localizable option. If the Default value is selected, the inspection is only performed if there is at least one resource file in the project. The Yes and No values allow enabling/disabling this inspection explicitly.
Select the desired value in the Localizable inspector option. If the Pessimistic algorithm is chosen, ReSharper looks for localizable strings in all elements, except those which have the attribute
Localizable(false). If the Optimistic algorithm is chosen, ReSharper analyzes only elements with the attributeLocalizable(true). Depending on these settings, ReSharper defines whether a specific string is localizable, highlights localizable strings and enables the corresponding quick-fix.
The easiest way to disable localization inspection for the current project is to press Alt+Enter over a highlighted string in the editor and use the corresponding command in the action list:
This command command sets the Localizable property in the current project to No.
Quick-fixes for localization issues
If a quick-fix is available for a code issue detected with localization inspection, ReSharper displays the corresponding action indicator on the left of your caret. You can press Alt+Enter or click on the indicator icon to see the list of available actions, To apply a desired action, click on it or select it in the list and press Enter.
Here are some quick-fixes for localization inspections:
Move to resource
This quick-fix invokes Move to Resource refactoring to move localizable string to a resource file. It is available when a string is highlighted with a curly underline.
Use resource entry instead of literal
If ReSharper detects that some string literal is already defined in resources, it suggests to replace the string with the corresponding resource usage:
After applying this quick-fix, the string is replaced with the resource usage.
Annotate type with 'Localizable(false)'
This group of quick-fixes sets false value to the Localizable attribute of the selected type.
Create resource file
If a resource file name is used in a code file, but you haven't created the resource file yet, ReSharper can do it for you. It highlights the resource file name in red and suggests the corresponding quick-fix: 
Create resource item
If a resource name is used in a code file, but you haven't declared this resource yet, ReSharper can do it for you. It highlights the resource name in red and suggests the corresponding quick-fix: 
Declare resource entry
If there are several cultures organised in a culture hierarchy, and there is a resource entry that is declared in a culture-specific resource file but is not declared in the default culture, ReSharper highlights the resource declaration and suggests the corresponding quick-fix:
After applying the quick-fix, resource declaration is inserted into the default culture where you can replace its value with a new one.
Override resource entry
If there are several cultures organised in the culture hierarchy and there is a resource entry, which is declared in the default culture but is not overridden in one or more other cultures, ReSharper highlights the name of resource and suggests the corresponding quick-fix(es):
After applying the quick-fix, resource declaration(s) is inserted into the culture-specific resource file(s) where you can specify correct values.
Remove resource entry
ReSharper suggests this quick-fix in the following cases:
A resource entry has equal values in neutral and specific cultures;
There are two or more declarations with the same resource name;
There are several cultures organised in the culture hierarchy and there is resource entry that is declared in specific culture, but is not declared in default culture.
After applying the quick-fix, resource declaration is removed from the current resource file.
Remove redundant resource entry type
Specifying the string type for a resource entry is redundant because it is the default resource entry type. ReSharper will suggest removing the redundant attribute:
Safe delete
If there are several cultures organised in the culture hierarchy and there is a resource entry, which is declared in the default culture but is not overridden in culture-specific resource files, ReSharper highlights the name of the resource suggests this quick-fix:
After applying this quick-fix, follow the steps of the Safe Delete Resource refactoring.
