  • What’s New in CodeRush for Roslyn v.16.2.5

    Team CodeRush continues our 45-day sprint/release cycle, and we have some treats for you in this update.

    All-new Symbol Naming Assistant

    This is a brand new feature designed to help you quickly name new symbols (members, variables, and parameters).

    The Naming Assistant window automatically opens when you start typing a new symbol name. The suggestion list is filtered as you type, and you can use a subset of the letters in the symbol you want to filter quickly. For example, in the screencast below, typing “mb” filters the suggestions to only show “modelBuilder”.



    Code Metrics Are Back

    Code Metrics were a popular feature in CodeRush Classic, and we’re pleased to announce the feature has been ported to CodeRush for Roslyn.

    Code Metrics reveal the complexity of each member, using one of three popular metrics (Cyclomatic Complexity, Maintenance Complexity, or Line Count).

    You can enable the feature on the Editor\All Languages\Code Metrics options page:


    Once enabled, metrics will appear to the left of the member declaration:


    You can select a different metric with the mouse, by clicking the metric number and using the menu:



    The CodeRush Decompiler gets some improvements. Anonymous methods now appear inline, nullable types are listed with the “?” modifier (e.g., “int?” instead of “Nullable<int>”), and XML documentation comments now appear in decompiled code.


    The References Window now lets you jump quickly among references. When the window is open, press F8 to jump to the next item and press Shift+F8 to jump to the previous item. Also, you can now use the Jump To dialog to navigate through all currently open files.


    Two new refactorings:

    • Move Type to Namespace changes the namespace of the active type and updates all references.
    • Introduce Using Statement replaces object creation and dispose code blocks with a using statement, improving code readability and ensuring locally-used objects are properly disposed.

    Smart Duplicate Line

    Now, when duplicating items in collection initializers and in parameter lists, commas are added automatically if needed.

    New Visualizations

    Two improvements to make it easier to understand what’s happening in your code:

    • Region Painting, which implements a low-contrast visual representation of **#region** directives, reducing visual noise where regions are used:


    • Output Window Highlighting, where errors and warnings in the Output window can be emphasized with saturation, making it easier to recognize important messages faster.


    We also addressed a number of reported issues. As always, we welcome your feedback.

    You can download the latest version of CodeRush for Roslyn from the Visual Studio Marketplace. Give it a try and let us know what you think!

  • CodeRush for Roslyn, v. 16.2.3 is Available

    Continuing our 45-day sprint/release cycle, today we release another update to CodeRush for Roslyn. Highlights of this release include powerful new refactorings & code providers, along with enhancements to Smart Duplicate Line.

    New Refactorings and Code Providers

    • Convert to Function – Allows you to easily convert a method that returns void into a function that returns the appropriate type (matching the type of the expression returned). I find myself frequently using this refactoring because it's fast, smart, and I can invoke it from inside the method (with the caret on a return statement). There’s no need to reach for the mouse or move the caret up to the declaration. Here’s what it looks like:

    • Convert to Procedure – This code provider is the opposite of Convert to Function. It converts a method that returns a value of any type to a proc that returns void (or a Sub in VB).
    • Extract Interface – This refactoring creates an interface based on the public members of the active class, and modifies the active class so it implements the extracted interface. 
    • Widen Scope (promote to field) - Use this to move a local variable declaration from inside a method body out to become a private field of the parenting class.

    Smart Duplicate Line Gets Smarter

    In our last release, we introduced Smart Duplicate Line (Shift+Enter). This feature is a real time saver, allowing you to create new lines of code modeled on existing lines of code. Smart Duplicate Line (SDL) looks for patterns in the surrounding code, and attempts to predict the parts you’re likely to change. As a result, SDL is great for declaring constants, enum elements, properties, and POCOs.

    In this release, we make SDL even smarter.

    For starters, SDL now works in XAML:


    And SDL now recognizes (and increments) patterns of numeric primitives of type integer, double, decimal, octal, float, and hex:

    SDL - Enums Hex

    And SDL can cycle through enum elements in the code automatically:

    SDL - enum cycle

    SDL is one of my favorite new features. Be sure to try it out (Shift+Enter) and let us know what you think, and also send us your suggestions for how we can make it even smarter.

    Other Enhancements

    • Paste Replace Word – Replaces the identifier under caret with the one on the clipboard in a single keystroke. Press Ctrl+B when the caret is on an identifier to immediately replace it with the contents on the clipboard.
    • Navigation features now support XAML bindings.
    • We added submenu support to the Code Actions menu, offering contextually-related actions (e.g., contract actions, spelling suggestions, etc.) in a single submenu (thereby cleaning up the main Code Actions menu).

    • We have added the ability to collect a marker and immediately paste clipboard contents at the target location using a single keystroke (Shift+Esc).
    • We have added a menu item allowing you to clear all markers dropped in the document.
    • You can now group Code Issues and References by folder containing the source code file.


    We also addressed a number of reported issues. As always, we welcome your feedback.

    You can always download the latest version of CodeRush for Roslyn from the Visual Studio Marketplace. Give it a try and let us know what you think!

  • CodeRush for Roslyn, v. 16.1.9 is Available

    Today DevExpress releases version 16.1.9 of CodeRush for Roslyn. This update resolves a number of reported issues, and adds support for Visual Studio 2017 RC.

    As always, you can download the latest version from the Visual Studio Gallery. And let us know what you think.

  • CodeRush for Roslyn update, version 16.1.8

    The 16.1.8 CodeRush for Roslyn update contains important new productivity features for Visual Studio.

    Smart Duplicate Line

    This is a feature you’ll definitely want to play with. Smart Duplicate Line duplicates the active line, and inserts Text Fields into the duplication to make modification easier. The feature learns your preferences as you use it, so it gets smarter (and saves you more work) over time.

    To use Smart Duplicate Line, place the caret on any line and press Shift+Enter.

    Here are a few examples of Smart Duplicate Line:



    Decompose Parameter

    This is a refactoring we’ve had in CodeRush Classic, but we’ve just now ported it to CodeRush for Roslyn. This is a very powerful refactoring that allows you to easily change the types of the parameters passed into a method, which can make the method is more widely accessible, promoting reuse.

    For example, you might have a method that accepts a large high-level class called “Person”, but inside that method you only access the Age property of that person. Decompose Parameter can simplify that method so it only accepts a numeric Age parameter, and update all calling locations.

    Here’s another example. I have a method called GetDistance that accepts two System.Windows.Points, but that parameter type ties the method down to a particular platform. To make this code more flexible and encourage reuse, we can apply Decompose Parameter to both of those Points, turning those parameters into doubles, so this method can be called from any app running on any platform:



    XAML Features

    • XAML Code Formatting
    • Import All Types (declares all necessary namespace references needed by the XAML file)

    Refactorings, Code Providers, and Code Formatters

    • Break Apart or Line Up both Parameters and Arguments – either collapses a list of method parameters or passed-in arguments into a single line, or breaks them apart into separate lines (one for each parameter or argument).
    • Remove Type Qualifier – removes the explicit namespace definition from symbol usage and adds the corresponding namespace reference to the file's using/imports list. You can use it on a single identifier, on all identifiers in the current file, or as a code cleanup rule.
    • Decompose Parameter (discussed above and shown below)

    • Extract String to Resource – Adds a string literal to an existing RESX file (creating the new RESX if necessary), and replaces the string with the resource link. You can also optionally extract all string literals within a method or accessor.
    • Declare Parameter – Adds the selected identifier to the method signature and updates all usages.

    Unit Testing

    Code Coverage now supports .NET Core test cases.

    Give It a Try

    As always, thanks for your support.

    You can grab a shiny new install of CodeRush for Roslyn from the Visual Studio Gallery. CodeRush for Roslyn starts at US$49 for the community support edition. A CodeRush license entitles you to a never-expiring product with a full year’s worth of updates. Updates happen approximately every 45 days.

    If you already have CodeRush for Roslyn installed you can check the CodeRush About box for version – make sure it’s at least 16.1.8. If it’s lower, use Visual Studio’s Tools | Extensions and Updates dialog to get the latest updates.

    You can see our full What’s New release history here.

  • CodeRush for Roslyn, v16.1.7

    Today CodeRush for Roslyn v16.1.7 is available. Team CodeRush continues its 45-day sprint & release cycle.

    This release adds a few new features, and addresses a number of customer-reported issues.

    My favorite new feature in this release is the availability of Reorder Parameters. This extremely efficient refactoring is now available at method calls, multi-dimensional indexed property references, and object creation expressions. So you can be anywhere in your code, and see a method call with arguments in non-intuitive places, and reorder that call’s parameters immediately, and CodeRush for Roslyn will update the declaration and all references automatically.



    Another nice addition is the return of being able to use the Spacebar to expand/collapse regions:



    And we improved the performance of the IntelliRush experience.


    We also discovered three undocumented features we added to the Debug Visualizer back in version 1.0.12, which you may have already experienced.

    1. Array contents preview at debug time:



    2. Color swatch preview at debug time:



    3. Font preview at debug time:

  • CodeRush for Roslyn 16.1.6 - Official Release

    It’s Here

    Team CodeRush has worked for over a year building CodeRush for Roslyn, and we’ve dedicated ourselves to creating the fastest, lightest, most powerful add-in for Roslyn. Here are a few of our accomplishments:

    • CodeRush loads in about three seconds or less.
    • CodeRush consumes significantly less memory than competing tools with similar functionality (about 200MB less for most projects).
    • CodeRush still appears to have the world’s fastest test runner.
    • We continue to approach a maximally efficient code writing experience.

    This past year the team obsessed over performance, working to create a tool that maximizes productivity without getting in your way. I think we did that, and I’m interested to see if you agree.

    Killer Features that made it into this release:

    Differences Between CodeRush for Roslyn and CodeRush Classic

    Here’s an overview of the major differences between CodeRush for Roslyn and CodeRush Classic:

    CRR vs CRC

    So if you’re working in C# or VB in Visual Studio 2015 or higher, then CodeRush for Roslyn will make sense for you.

    If you’re working in older versions of Visual Studio, or if most of your work is in JS, HTML, or XAML, CodeRush Classic may right be for you.


    There are two ways to purchase CodeRush for Roslyn. If you need first-class DevExpress support, or if you also need CodeRush classic, then you’ll want to purchase CodeRush Ultimate.

    If support from the community is all you need and you’re working in VS 2015 and up, then get CodeRush for Roslyn, Community Support Edition.

    Both options are summarized below:

    CRR vs CRU

    Note that regardless of which option you purchase, that purchase price entitles you to one year’s worth of free product updates. And speaking of updates…

    Release Schedule

    If you followed the CodeRush for Roslyn pre-release, you know that Team CodeRush pushed out updates every 45 days. And we plan to continue that 45-day sprint cycle, so you can expect to get the latest features, refactorings, updates, and every 45 days. Eight times a year.

    What’s New

    Here’s what’s new in the 16.1.6 release:

    Code Analysis

    • You can now run Code Analysis for the active project or file separately.
    • The Code Analysis report now includes information about source files.
    • You can now reconfigure Code Analysis without restarting Visual Studio.
    • We have added the ability to check naming conventions continuously in background.
    • Performance has been improved.


    • ‘The new Jump to Everything navigation provider allows you to jump to any file and symbol in the solution.


    Refactorings and Code Providers

    • Convert to System Type/Built-in Type lets you easily switch between CLR types and their keyword aliases.
    • Split String divides a string into two at the caret position. You can also divide one string into three concatenated strings - just select the portion you want to break out before applying this refactoring.
    • Reorder Parameters changes method parameter order, without any dialogs to slow you down. The method signature and all references are updated. This is the fastest, most effortless way to reorder parameters.
    • Visual Studio's Rename refactoring is now accessible from the refactoring menu. 
    • We have added the ability to sort Light Bulb menu items (refactorings and code providers) based on their most recent usage in the given context.
    • You can now optionally hide redundant Light Bulb menu items provided by Visual Studio if these features overlap more efficient CodeRush functionality. For example, if this option is selected, when CodeRush's "Declare Method" is available, Visual Studio's "Generate method stub" menu item will be hidden.

    Test Runner

    In this release, we are introducing beta support for .NET Core tests. Now you can run and debug .NET Core tests, created with NUnit, xUnit or MSTest frameworks.

    • Test Runner output in Visual Studio's Output window now shows the filter applied to the test run:
    • You can now optionally show or hide the Test Runner and Code Coverage items appearing in Visual Studio context menus.
    • Visual Studio's status bar now displays the currently running test.
    • Testing results in Visual Studio's Output window are now grouped by project.
    • Tests can now be grouped by file path.
    • A number of minor usability issues were corrected/improved.

    Other Improvements

    • If you have new and old versions of CodeRush for Roslyn installed, the Extension Cleaner will detect this and offer to clean up the older versions.
    • The Code Cleanup options page has been redesigned, showing before & after code samples, so you can more easily see what each option performs.
    • Member Icons are now in vector format, so they look sharp and clear regardless of the color scheme, display resolution or editor window scale.

    CodeRush for Roslyn, 16.1 - Code Template Example

    CodeRush is well-known for its code templates, guided by a set of easy-to-learn rules for writing code quickly. In our port to Roslyn, we kept CodeRush’s unrivaled code template technology and worked to amp up developer efficiency everywhere we could.

    Code templates are like code snippets – they offer a shorter path between thought and actual code. They are like a compression mechanism for writing code. So your mind and your fingers do less work, and it takes less time to turn your ideas into working code.

    For example, let’s say we want to create a new public enum called “Vowels”, with five elements, “a”, “e”, “i”, “o”, and “u”. Something like this:

      public enum Vowels

    To create this by hand in C# it takes 11 keystrokes to enter those six names (“Vowels”, “a”, “e”, etc.) and another 27 keystrokes to create the syntax that makes it an enum:

    1. p
    2. u
    3. b
    4. l
    5. i
    6. c
    7. Space
    8. e
    9. n
    10. u
    11. m
    12. Space
    13. V
    14. o
    15. w
    16. e
    17. l
    18. s
    19. Enter
    20. Shift+
    21.          [    // for “{“ on a US keyboard
    22. Enter
    23. a
    24. ,
    25. Enter
    26. e
    27. ,
    28. Enter
    29. i
    30. ,
    31. Enter
    32. o
    33. ,
    34. Enter
    35. u
    36. Shift+
    37.          ]    // for “}“ on a US keyboard
    38. Enter

    We could use Visual Studio’s code snippets to improve our efficiency, saving 10 keystrokes. Nice. In this case it still takes 11 keystrokes to enter “Vowels”, “a”, “e”, etc., and another 17 keystrokes to create the code that makes it a syntactically correct enum:

    1. p         // wait for Intellisense to suggest “public” – if it doesn’t you have more typing
    2. Tab     // expands VS snippet
    3. Space
    4. e         // wait for Intellisense to suggest “enum” – if it doesn’t you have more typing
    5. Tab     // expand “enum”
    6. Tab     // expand enum snippet
    7. V
    8. o
    9. w
    10. e
    11. l
    12. s
    13. Enter  // moves caret into enum
    14. a
    15. ,
    16. Enter
    17. e
    18. ,
    19. Enter
    20. i
    21. ,
    22. Enter
    23. o
    24. ,
    25. Enter
    26. u
    27. Down Arrow
    28. Enter

    So using Visual Studio code snippets seems to improve the developer experience. We eliminate the need to hold the Shift key down when pressing the brace keys (simplifying our task and lowering cognitive load), but we’re still required to hit that comma key, which is small and requires more precision to hit (and is a more error prone key to hit) than the much larger Enter key, for example.

    Now compare the code snippet experience with CodeRush template expansion, which looks like this (11 keys to name the elements, plus 8 keys to create the syntax):

    1. e
    2. Tab      // …or Space, depending on your settings. Either way, this expands the public enum template instantly.
    3. V
    4. o
    5. w
    6. e
    7. l
    8. s
    9. Enter   // moves caret into enum
    10. a
    11. Enter   // comma added automatically
    12. e
    13. Enter   // comma added automatically
    14. i
    15. Enter   // comma added automatically
    16. o
    17. Enter   // comma added automatically
    18. u
    19. ;        // smart semicolon ends the enum declaration and moves the caret outside

    In all three approaches we are creating the exact same code. And each example demands a different level of developer effort.

    So for each of these approaches, the minimum number of keys needed to declare only the syntax (e.g., no element names) are summarized in the chart below:



    Using CodeRush’s “e” template to quickly create enums.

    Wrap Up & Benefits

    This gives you an idea of the kind of compression we’re talking about when you use CodeRush templates to write code syntax. In many of the CodeRush templates, including the enum template discussed here, we have achieved what we believe is the most optimally efficient way to write code. Fewest keystrokes. Lightest cognitive load.

    There are a number of reasons why you might want to be able to write more code with less work:

    • Your fingers do less work. Less strain over the course of a lifetime may increase the longevity of your hands.
    • Typing fewer keys means fewer opportunities to introduce mistakes. Fewer mistakes means less time wasted correcting.
    • You can write code faster. Useful when you’re pair programming, competing in a hackathon, or presenting/coding live in front of your team or an audience.
    • Writing code faster also shortens the feedback loop between idea and realization, which can lead to a higher quality design.
    • The more experience you get writing code, the better you get. If you write more code in less time, your experience will come at a faster rate.

    If you’re already using Visual Studio snippets, that’s a good sign. It shows you value getting more done with less effort.

    Note that CodeRush templates tend to be more than twice as efficient as Visual Studio’s snippets. So if efficiency, longevity or coding speed is important to you – and you’re not using CodeRush templates – you might want to take a closer look.

    Speaking of closer looks, Paul Usher has a CodeRush for Roslyn webinar on 2 August 2016. Check it out.
