This refactoring allows you to change name of any symbol defined in your solution. All references to and usages of the symbol are updated automatically.
Using the refactoring for different C# entities
Here is the list of C# entities that you can rename with this refactoring:
Namespace You can also change its nesting level of the namespace. For example, you can rename namespace A.B.C to A.D.
Type If the renamed type is located in file with the same name, ReSharper renames the file, too. If the renamed type is a part of a hierarchy of types with similar names, e.g. class Foo : IFoo, you will be able to choose whether to rename the related types.
Method If the method is a part of inheritance/implementation hierarchy, the related methods are renamed as well. If the method has overloads, you will be able to choose whether to rename the overloads.
Field If the field is used in a property with a matching name, you will be able to choose whether to rename the property.
Property If the property has a backing field with a matching name, you will be able to rename the field as well.
Parameter If the method is a part of inheritance/implementation hierarchy, or has overloads with a parameter of the same name and type, you will be able to rename parameters in the related methods, too.
Local variable ReSharper renames local variables without the dialog:

Invoking the refactoring with a command
To rename a symbol and update all references and usages
Select a symbol in one of the following ways:
In the editor, set the caret at the name of a symbol.
Right-click and choose Refactor | Rename in the context menu.
Choose ReSharper | Refactor | Rename… in the main menu.
The Rename dialog will open.
Type a new name for the symbol or use one of the suggested names. ReSharper suggests new names for the symbol taking into account your naming style.
ReSharper can provide the list of related symbols in comments and string literals and rename them on demand. If you need it, select the Search in comments and string literals.
Click Next. If there are nothing related to the renamed symbol, ReSharper applies the refactoring. Otherwise, the wizard displays additional steps:
If there are related symbols with similar names, they are listed on the following step: Select related symbols that you want to rename along with the selected symbol - you can accept the suggested names or specify new names in the New Name column.
If you have previously selected Search in comments and string literals and occurrences of the symbol name is found, they are listed on the following step: Select textual occurrences that you want ReSharper to rename.
If no conflicts are found, ReSharper performs the refactoring immediately. Otherwise, it prompts you to resolve conflicts.
Performing the refactoring in-place
You can rename a symbol by modifying its declaration right in the editor and then applying a quick-fix to invoke the solution-wide refactoring.
As soon as you change symbol's name at its declaration, a grey border appears around the name, notifying you that the refactoring is available. You can press Alt+Enter to find the refactoring in the action list:
