Use explicit or implicit tuple component name | Switches between explicit and implicit tuple component name. Available on tuple components references. |
Use format string | Converts concatenation of a few strings and other objects to the use of 'String.Format' method For more information, refer to code analysis and helpers for string literals. |

Use 'MinBy' or 'MaxBy' | Use 'MinBy' or 'MaxBy' instead of ordering and taking 'First' or 'Last' |
Use 'nameof' expression to capture name of entity | Uses 'nameof' expression to capture the name of an entity instead of hard-coding it in a string literal |
Use object/collection initializer instead of assignments/.Add() method calls | Replaces series of assignments or 'Add()' invocations with object or collection initializer expression For more information, refer to code inspection: use object or collection initializer when possible. |
Use positional deconstruction pattern | Replaces property pattern member(s) of recursive pattern with positional deconstruction patterns |
Use separate declarations in deconstruction declaration/patterns | Replaces single declaration with separate variable declarations inside deconstruction |
Use Span<T> for stack allocated variable | Uses Span<T> for stack allocated variable |
Use string interpolation | Converts concatenation of a few strings and other objects to the use of string interpolation |
Use 'System.Environment.NewLine' value | Uses 'System.Environment.NewLine' instead of "\n", "\r" or "\r\n" literal |
Use 'System.String.Empty' value | Uses 'System.String.Empty' instead of "" literal |
Use target-typed new | Simplifies 'new' expression by removing explicit type specification |
Use type alias | Use selected type alias where possible |
Use 'var (...)' syntax for deconstructing declarations with multiple variables | Allows replacing a declaration with multiple variables with explicit types with 'var (...)' syntax, making them all implicitly typed |
Write documentation | Write XML documentation for declaration |
