Moving up from CodeRush Xpress to CodeRush

Considering an upgrade from CodeRush Xpress to the full version of CodeRush? This post is for you. For anyone who needs an overview of features shipping in CodeRush Xpress, see this page on MSDN:

The difference, in a nutshell: CodeRush packs in 150 more refactorings, code template technology (think Visual Studio's code snippets on steroids), more coding tools, more visualization tools, more navigation tools, and many more useful features. Additionally the full version of CodeRush also includes support for languages other than C#, like ASP.NET, XAML, Visual Basic, Javascript, and C++. And because the full version of CodeRush is the primary focus of DevExpress' IDE Tools team, the latest greatest features & refactorings will always show up there first.

For clarity, features that are part of CodeRush Xpress appear here in a light red font, followed by a corresponding list of additional features only available in the full version of CodeRush.

Other CodeRush Features

Clipboard Tools

CodeRush Xpress includes the following clipboard tools:

  • Smart Cut/Copy
  • Paste Replace

The full version of CodeRush includes the clipboard tools listed above, as well as the following additional clipboard tools:

Intelligent Paste

Intelligent paste modifies the text from the clipboard before inserting it into the editor. Here's a sampling of some of the intelligent pastes defined for C#:

Name / Description Sample Clipboard/Paste
Typecast. Converts an "is" test to a typecast myVar is MyClass
Declaration. Converts a statement that creates a new object into a declaration. myVar = new MyClass();
private MyClass myVar;
Assignment. Converts a relational expression to an assignment. aaa != bbb
aaa = bbb;
Expression. Converts an assignment to an expression when pasted inside parens. aaa = bbb;
aaa == bbb
New Method. Creates a new method declaration from a method call when pasted on an empty line outside a method or property. MyMethod();
public void MyMethod()

Clipboard History

The Clipboard History tracks up to 64 of your most recent clipboard cut and copy operations, syntax-highlights them using the same colors you use in Visual Studio, and lets you easily paste them into Visual Studio.


Code Providers

Code Providers make intelligent changes to your code. Just select or place the caret on the code you want to change, and press the CodeRush/Refactor! key.

CodeRush Xpress includes the following code providers to declare elements based on usage:

  • Types

    • Declare Class
    • Declare Delegate
    • Declare Enum
    • Declare Enum Element
    • Declare Interface
    • Declare Struct
  • Members
    • Declare Constructor
    • Declare Event Handler
    • Declare Getter
    • Declare Method
    • Declare Property
    • Declare Property (auto-implemented)
    • Declare Property (with backing field)
    • Declare Setter
  • Variables
    • Declare Field
    • Declare Local
    • Declare Local (implicit)

The full version of CodeRush includes all the declaration features listed above, as well as the following:

  • Add Else Statement
  • Add Missing Constructors
  • Add Setter
  • Create Descendant
  • Create Descendant (with virtual overrides)
  • Create Implementer
  • Create Method Stub
  • Invert Selection
  • Mirror Code
  • Remove Region Directives
  • Remove Setter
  • Rotate 90 Degrees

Add Missing Constructors and Create Descendant are two of my favorites in that list. There is also Rotate 90 Degrees, which works on a selection of code...

 Rotate 90 Degrees

Rotate 90 Degrees turns code operating in two-dimensional space across the axis. In the example above a copy of a method which distributes controls evenly left-to-right becomes a new method that distributes controls evenly top-to-bottom.

In addition to the code providers listed above, you also get Intellassist to suggest in-scope identifiers while you type, and auto-completion for parentheses and brackets.

Code Templates

Code templates are a huge part of the efficiency gains offered by the full version of CodeRush. Code templates are like Visual Studio's code snippets on steroids. They're extensible, more powerful, easier to use, and include their own editor. They also offer significant gains to developers working in more than one language, or to developers transitioning from one language to another.

To see CodeRush templates in action, check out this video by CodeRush customer Kim Major. Also, we've published a number of CodeRush training videos that cover templates, including this introduction.

Also, we've created a shortcuts sheet that includes a number of template and feature shortcuts to make it easier to exploit this powerful technology.

CodeRush Shortcuts

CodeRush Xpress does not include Code Template technology.
