Code Cleanup

This page of JetBrains Rider options allows you to manage and configure custom cleanup profiles, as well as to assign a cleanup profile for the silent code cleanup. The two default profiles (Full Cleanup and Reformat Code) are also shown here. You cannot modify modify them, but you can clone them to make new custom profiles.

Toolbar controls

Use the following controls to configure the selected cleanup profile:

Item	Description
Add	Click this button to create a new custom Code Cleanup profile. As soon as a new profile is created, it opens in the editing mode, where you can configure the list of cleanup tasks.
Set as default	Click this button to use the selected profile for silent cleanup.
Duplicate	Click this button to create a copy of the selected profile. If you have default settings, you will need to duplicate one of the default cleanup profiles to create a custom cleanup profile. As soon as a new profile is created, it opens in the editing mode, where you can configure the list of cleanup tasks.
Rename	Click this button to rename the selected custom profile. Note that default profiles (Full Cleanup and Reformat Code) cannot be renamed.
Remove	Click this button to remove the selected custom profile. Note that default profiles (Full Cleanup and Reformat Code) cannot be removed.

Code cleanup tasks for selected profile

These tasks become configurable for the selected custom cleanup profile. Initially, there are no custom profiles and tasks of the default profiles cannot be edited. You can click Duplicate to create an editable copy of one of the default profiles and then edit its tasks.

Cleanup task	Description
C#
Apply file layout	Reorders type members.
Update file header	Inserts or updates the file header comment.
Code Styles
Use explicit or implicit modifier definitions for types	Applies the rule for type modifiers - whether on not to use the `internal` modifier explicitly. The rule is configurable on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Modifiers.
Use explicit or implicit modifier definitions for type members	Applies the rule for type member modifiers - whether on not to use the `private` modifier explicitly. The rule is configurable on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Modifiers.
Sort modifiers	Applies the preferred order of type/member modifiers. The rule is configurable on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Modifiers.
Apply arguments style (named \| positional)	Applies the preferences for named/positional arguments for specific types of parameters. The preferences are configurable on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Named/Positional Arguments.
Remove redundant parentheses	Removes redundant optional parentheses in cases specified on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Optional Parentheses.
Add parentheses to explicitly specify operation precedence	Adds optional parentheses to clarify precedence of operations in cases specified on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Optional Parentheses.
Add/remove braces around single statements	Adds or removes optional braces around single nested statements as specified on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Braces for Single Nested Statements.
Arrange attributes	Applies the rules for multiple attributes as specified on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Multiple Attributes.
Enforce 'var' keyword usage settings	Applies the rules for 'var' usage during the cleanup. The rules are configurable on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`).
Remove code redundancies	On the Editor \| Inspection Severity page of JetBrains Rider settings (`Ctrl+Alt+S`), in the Redundancies in Code categories for most languages, JetBrains Rider lists over 50 redundancies that have associated code inspections. Some of them require special attention, and you simply cannot process them in the batch mode. That leaves Code Cleanup with about 30 redundancies that it is able to remove automatically whenever you select Remove code redundancies in your cleanup profile. Specifically, code cleanup: Removes: Redundant empty constructors. Explicit integer type specifiers in enumerations. `true` specifiers in `for` statements. Redundant type casts. Redundant parentheses from attributes without arguments. Explicit calls to base class constructors without arguments. Redundant boolean comparisons. Redundant braces from collection initializers with a single expression. Redundant explicit delegate creation expressions. Empty argument lists from object/collection initializers. Redundant `new` keywords. Redundant `partial` modifiers on type declarations where a type has a single part. Redundant `unsafe` contexts and statements. Redundant `object.ToString()` calls (for example, in a concatenation with a string or as an argument of a `string.Format()` call). Redundant `string.ToCharArray()` calls. Redundant specifications of argument types. Signatures in anonymous methods where its parameters are not used in the method body. Non-referenced labels. Redundant field initializers. Redundant explicit names in anonymous type properties. Redundant nullable types where value type is implicitly convertible to nullable. Converts: Nullable types to short form `Nullable<T>` to `T?`). Static method invocations to extension method calls where extension methods are invoked as static methods. To implicitly typed array creation expressions when array type can be inferred from initializer. Fixes: Occurrences where static members of a type are accessed via derived members of the type.
Use auto-property, if possible	Replaces simple properties and corresponding backing fields with auto-properties. For more information, see Using Auto-Properties.
Make field read-only, if possible	Adds the 'readonly' keyword to fields that are assigned in the declaration or in a constructor and only have read usages. For more information, see Making Fields Readonly.
Make auto-property get-only, if possible	Removes the redundant `set` accessor on auto-properties that are initialized from the constructor/initializer and have no write usages. Note that this task only works for C# 6.0. By default, JetBrains Rider automatically detects C# version based on the associated compiler. However, you can specify the target C# version explicitly — press `Alt+Enter` on the project in the Solution Explorer and use the Language level selector on the Application page of the Project Properties dialog..
Arrange qualifiers	Applies the rules for qualifying type members. The rules are configurable on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Optional Member Qualifiers.
Fix built-in type references	Applies the rule for built-in type names (C# keyword or CLR type name). The rule is configurable on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Code Syntax Style: Built-In Type References.
Optimize 'using' directives	Provides the following configurable options: Optimize 'using' directives Removes unused namespace import directives and sorts the namespace import directives: all `System.*` namespaces go first, sorted alphabetically by the second word after the dot; all other namespaces go next, in alphabetical order.. For more information, see Code Syntax Style: Namespace Imports. Embrace 'using' directives in region If this check box is selected, a new region for wrapping all namespace import directives is created during cleanup. Region name Allows specifying a name for the region wrapping namespace import directives.
Shorten qualified references	Replaces fully qualified names with short names when possible by importing namespaces, implementing settings configured on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`).
Reformat code	Reformats your code according to the preferences that you can configure on the Editor \| Code Style \| C# \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Managing and Applying Code Formatting Rules.
Reformat embedded XML doc comments	Reformats XML doc comments. Note that JetBrains Rider does not reformat plain comments like: `// A plain single-line comment` or `/* A plain multi-line comment */`
ASP.NET
Optimize @Register directives	Removes unused `@Register` directives.
HTML
Reformat code	Reformats your code according to the preferences that you can configure on the Editor \| Code Style \| HTML \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Managing and Applying Code Formatting Rules.
Normalize quotes around attribute value	Applies the preferred quote style: single quote (') or double quote (").
JavaScript/TypeScript
Terminates statements	Terminates JavaScript statements with the semicolon.
Normalize quotes around string literal	Applies the preferred quote style: single quote (') or double quote ("). The preference can be configured on the Editor \| Code Style \| TypeScript \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`).
Correct 'var' to 'let'/'const' where possible	`let` and `const` are supported in the following cases: In JavaScript code, if the target JavaScript language level is ECMAScropt 6 (you can choose it on the Languages & Frameworks \| JavaScript page of JetBrains Rider settings (`Ctrl+Alt+S`) ) In TypeScript 1.4, if the target ECMAScript 6 is selected in the project properties. In TypeScript 1.5 or above.
Move block-scope variables to most possible inner scopes	Moves variables defined outside of a function/compound statement, etc. closer to their usages if there are no other usages in outer scopes.
Convert string concatenations to template strings	In JavaScript code, if the target JavaScript language level is ECMAScropt 6 (you can choose it on the Languages & Frameworks \| JavaScript page of JetBrains Rider settings (`Ctrl+Alt+S`) ), as well as in TypeScript 1.4 or above, this option will convert string concatenations to template strings. For example: `var str1 = "Hello,"; var str2 = "Test: " + str1 + " World1";` will be converted to const str1 = "Hello, "; const str2 = `Test: ${str1} World1`;
Reformat code	Reformats your code according to the preferences that you can configure on the Editor \| Code Style \| JavaScript \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Managing and Applying Code Formatting Rules.

Add explicit 'any' type annotation if needed	This options lets you add explicit 'any' annotation to types according to settings configurable on the Editor \| Code Style \| TypeScript \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`).
Synchronize type annotation presence with code style	This options lets you enforce explicit/implicit typing according to settings configurable on the Editor \| Code Style \| TypeScript \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`).
Fix relative path style in 'require' if needed	Applies the Relative file reference style in 'require' code style preference for relative paths in the `require` keyword. For example, `import X = require("file1")` or `import X = require("./file1")`. You can configure this preference on the Editor \| Code Style \| TypeScript \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`).
Use 'as' instead of type assertions	Replaces `var bar = <string> foo;` with `var bar = foo as string;` which is a recommended way to avoid ambiguity with JSX syntax.
XAML
Collapse empty tags	Removes the closing tag if the tag is empty.
XML
Reformat code	Reformats your code according to the preferences that you can configure on the Editor \| Code Style \| XML \| Code Style page of JetBrains Rider settings (`Ctrl+Alt+S`). For more information, see Managing and Applying Code Formatting Rules.
