CodeRush - Visual Studio Productivity Tools Are Available Free-of-Charge in v22.1!

21 June 2022

Available Free-of-Charge to Everyone

With our most recent release (v22.1), we’re making CodeRush available free-of-charge. If you’re not familiar with CodeRush, you can learn more about its feature set here and download your copy today at We have redesigned the landing page to describe its most popular features – those used most by CodeRush customers.

If you’ve used CodeRush in the past or are familiar with capabilities, you can read what’s new in v22.1 below.

What's Else Is New in CodeRush v22.1?

As you may recall from our CodeRush's strategy blog post, our #1 goal is to help you save time – wherever/whenever possible. In the recent past, we released the following shortcuts for DevExpress customers: XAF Templates | XPO Templates | Blazor Component Templates

For our v22.1 release cycle, the CodeRush team allocated most of its resources to Best Practice Diagnostics & Fixes. NOTE: Owners of active DevExpress Universal, DXperience, and CodeRush subscriptions were already entitled to this new functionality. To provide access to the same benefits, owners of active DevExpress WinForms, ASP.NET, WPF Subscriptions have been automatically assigned a free license of CodeRush (as of today). 

DevExpress XAF and XPO Error Diagnostics

You can now analyze your solution with pre-built error diagnostics and view a detailed report in the Error List window. v22.1 includes the following new diagnostics to help you correctly define your business model and controllers:

  • XAF0009: Properties decorated with the 'RuleRequiredFieldAttribute' should be of nullable or reference type.
  • XAF0010: Set the 'DelayedAttribute.UpdateModifiedOnly' property to True.
  • XAF0011: Implement the delayed property correctly.
  • XAF0012: Avoid calling the 'XafApplication.CreateObjectSpace()' method overload without the 'Type' parameter.
  • XAF0013: Avoid reading the 'XafApplication.ConnectionString' property.
  • XAF0014: The property with the 'Association' attribute must have a correct unique pair.
  • XAF0015: Association must not have the 'Aggregated' attribute if it is paired to the 'many' end of the association.
  • XAF0016: Descendants of 'NonPersistentBaseObject' and 'NonPersistentLiteObject' must be decorated with the 'DomainComponent' attribute.

DevExpress WinForms Error Diagnostics

You can now detect C# code errors as you type. You can check errors (if any) in the code editor and in the Error List window.
Code Diagnostics - WinForms UI Controls | DevExpress

Install the 'DevExpress.Win.CodeAnalysis' package to enable Code Diagnostics. The analyzer requires Visual Studio 2019 or a newer version, and supports both .NET Framework and .NET 5+.


DevExpress WPF Error Diagnostics

CodeRush can now check XAML code for DevExpress component-related usage issues and help you follow best practices with modern code. v22.1 includes diagnostics for the following issues and legacy practices: 

  • Legacy drag-and-drop - Drag-and-Drop Managers are a legacy way to enable drag-and-drop. Consider setting the 'DataViewBase.AllowDragDrop' property to 'true' instead.


  • ColumnBase.EditTemplate is used - The 'EditTemplate' property is outdated. Consider using CellEditTemplate instead.

  • FieldName matches the Binding path - When the Binding property is specified, 'FieldName' should not contain an existing property name.


  • Outdated windows The DXWindow, DXRibbonWindow, and DXTabbedWindow classes are outdated. Use ThemedWindow instead.

  • Cell templates missing PART_Editor - Consider setting the editor’s Name to 'PART_Editor' to automatically bind and configure the editor.


  • EditValueChanging/EditValueChanged is handled in CellTemplate - Due to the grid's virtualization mechanism, this event handler will be invoked whenever a user scrolls data. Consider handling 'CellValueChanging/CellValueChanged' (for the grid's View) instead.


  • An invalid EventToCommand.EventName - The EventToCommand's associated object is missing the event specified in EventName.


  • In-place editing is unavailable when NavigationStyle is set to Row or None - Setting the 'ColumnBase.AllowEditing' property to 'true' will have no effect if the 'DataViewBase.NavigationStyle' property is set to 'Row' or 'None'.


  • AutoWidth and relative column size are used together - Setting the relative (star) column size will have no effect if the 'TableView.AutoWidth/TreeListView.AutoWidth' property is set to 'true'.
