Announcing CodeRush Xpress for C#

Developer Express and Microsoft are proud to announce a new version of CodeRush licensed exclusively for C# developers working in Visual Studio. The new product is called CodeRush Xpress, and it includes a fresh selection of hand-picked features taken from CodeRush and Refactor! Pro.

Here's a sampling of what you get:

Find any File or Symbol...

Go to any file or symbol in the solution efficiently.

Quick File Navigation

Type in a few letters of the name to filter...

Quick File Navigation-call

Or hold down the shift key to filter only on uppercase letters...

Quick File Navigation-R

Uppercase characters can appear anywhere. Any uppercase characters not specified in the filter are highlighted in blue...

Quick File Navigation-RC

The uppercase letters need not be sequential. Notice how "RD" in the screen shot below matches both "ResolveDelegate.cs" and "ResolveCallbackDelegate.cs"

Quick File Navigation-RD  

Tab to Next Reference

This is a really cool navigation feature that takes you to the next (and previous) reference just by pressing the Tab key (or Shift+Tab key to go backwards) when the caret is inside an identifier, member, or a type. For example, in the following code, the caret was inside the last Person type reference (in the "new Person()" instantiation call) when the Tab key was pressed, causing the Person reference at the top of the file to become highlighted.


Expand/Shrink Selection

This feature allows you to increase a selection by logical blocks, or decrease an expanded selection by the same logical blocks. This feature is perfect when refactoring, since many refactorings work on a contiguous selection of code (e.g., extract method, introduce local, etc.).

TDD-Style Intelligent Declaration Based on Usage

Place the caret on any undeclared element in your code and press the Refactor/Code key (Ctrl+`) to see list of intelligent suggestions for the type of the new variable. For example, in the screen shot below two appropriate types are suggested, even though Console.WriteLine has many overloads that accept a wide variety of types.


You can even turn a function call or property access into a variable declaration.


This makes writing code with Visual Studio's Intellisense really fast. Just use Intellisense to produce the property reference or function call, and then press the Refactor/Code key to declare a new local variable of the appropriate type. Here's an example with a function call -- notice the caret can be just about anywhere on the function call, even at the end of the line.


You can even declare a local from a simple instantiation, like this:


And it's worth noting you can declare all kinds of elements based on usage, not just locals. Anything you need types, members, fields -- the full list of elements that can be declared appears below.

Professional Grade Refactorings

CodeRush Xpress includes many powerful refactorings to help improve the quality of your code. For example, consider the following:

    private static void ShowInt(int n)
private static void ShowEntries(List<int> entries)

With the caret on the ShowInt method reference, you can press the Refactor! key...


and then select Inline Delegate. This will produce the following code:

    private static void ShowEntries(List<int> entries)
delegate(int n)

Notice the caret is on the delegate keyword. You can immediately press the Refactor! key again...


Note that we can go in two directions now. We can either convert the anonymous method to a named method (in essence reversing the Inline Delegate refactoring we just performed), or we can take it a step further and compress the anonymous method into a lambda expression. Choosing Compress to Lambda Expression, we get the following:

    private static void ShowEntries(List<int> entries)
      entries.ForEach(n =>

CodeRush Xpress is loaded with powerful refactorings taken from Refactor! Pro. One of our favorites, Extract Method to Type, allows you to extract a method from one type into another, updating both the calling code and the extracted method appropriately. For an example, consider the following code:

  class Person
    public string Name { get; set; }
    public bool IsAnOrphan { get; set; }
    public Person Mother { get; set; }
    public Person Father { get; set; }
// ...
  class BabyMaker
    public Person MakeOne(Person mother, Person father, string name)
      Person newBaby = new Person();
      newBaby.Name = name;
      newBaby.Mother = mother;
      newBaby.Father = father;
      newBaby.IsAnOrphan = newBaby.Mother == null && newBaby.Father == null;
      return newBaby;

Notice that the code in the MakeOne method contains a local variable that's an instance of type Person, and that code sets the IsAnOrphan property. There is some logic in this method that pertains to Person, but it feels like it's in the wrong class!

We already have the class Person in our solution, so it makes sense to move some of this code to the proper class. With CoderRush Xpress installed, all we need to do is select the code we want to move....


Press the Refactor key...


And choose "Extract Method to Person". CodeRush Xpress analyzes the selection and determines there's at least one local variable of a type you have declared elsewhere in the solution. Now let's apply this refactoring...


Press the Up and/or Down arrow keys to select a location for this new method, and press Enter to commit. Give the method a meaningful name...


Cool. Now we have the logic (that should have been inside Person to start with) right where it belongs. Notice how the new SetParents instance method works on the instance itself (compare that code with the original code that operated on the newBaby local). The code is easier to read and cleaner in both locations.

Notice also that tiny dark blue triangle, in the code above. That's a stack-based marker, and CodeRush Xpress drops markers automatically whenever you apply a refactoring or TDD-style declaration that takes you away from the original location. You can jump back at any time to the top marker on the stack by pressing Escape.

There are many more refactorings and cool features in CodeRush Xpress. This is just a preview. Here's the full list of what you get:

Mark, can I use CR Xpress along with the paid, full version of Refactor! Pro.

Hope so. Can't wait to play with this.

I installed "CodeRush Xpress for Visual Studio" and it has killed my "Refactor! for VB". Is that right or have I done something wrong?

Seems like a very nice tool but eats too much memory in my opinion (+- 100mb on new project, can go up to 200+MB on large projects). Is this normal or am is there something wrong with my machine?

Very nice but I HATE the smart copy feature.  I like to hit ctrl c or ctrl x to copy/cut the whole line instead smart copy copies only the word.  I HATE IT and I need to turn it off.


November 4, 2008 4:26 PM


I know there are a lot of shortcuts for CodeRush. How do I go about leaning about them? Is there a tutorial or a help file I can look at?

NM. I checked the forums and found the answer -

Emad, with regard to smart cut/copy, you can still get the entire line if you place the caret at the start of the line.

I have CodeRush Xpress installed, but can't find a menu option or keystroke to use the "Quick Find Navigation" feature. How do I get to it?

November 23, 2008 2:17 PM



I have the same question Nick Portelli does: is it possible to change default colors? I have customized my Visual Studio's editor colors (background is now almost plain black) and default colors are hardly visible...

Mark Miller - Appreciate that you can still cut/copy the whole line via that method but that's a tad slower; I'd just rather disable smart copy, is this possible?

January 6, 2009 10:54 AM


Installed it today, responsiveness has gone down.

VS2008SP1's ctrl+. functionality is gone (even after uninstall).

Hope my settings import will bring it back.

What have I done wrong? What steps should I take to get the standard VS features together with the new stuff?
