# What's New in v21.1.5 ## Performance Enhancements This release brings the following performance enhancements to CodeRush: ### Improved First-time Loading Performance CodeRush tool windows now load faster when run the first time. We've also decreased the time required to expand code templates the first time. ### Optimized Memory Use in the XAML Engine We've reduced memory consumption in the XAML engine which used in refactorings, navigation, code analysis, and other CodeRush features for projects containing XAML files. ## Test Runner The [Unit Test Runner](https://docs.devexpress.com/CodeRushForRoslyn/401723/configuration-options/unit-testing/test-runner) now shows white spaces and line breaks in test run results. ![](https://i.imgur.com/ZCpgTJK.png) Note: This feature is not yet supported in .NET Core projects. ## Short Descriptions for WN Hint **Performance Enhancements** * Faster first-time load performance for CodeRush tool windows. * Decreased time for first-time code template expansion. * Reduced memory consumption in XAML engine for refactorings, navigation, code analysis, and other XAML features. **Unit Test Runner** White spaces and line breaks are now displayed in test run results. ## Resolved Issues [T1013882](https://www.devexpress.com/issue=T1013882) - Code Cleanup - The "Unused type" rule does not support records in C# 9 [T1008699](https://www.devexpress.com/issue=T1008699) - Formatting - The indent is calculated incorrectly in the C# 8.0 switch expression [T1012132](https://www.devexpress.com/issue=T1012132) - Navigation - "Jump to symbol" navigation performs an endless search when all files are closed [T1013688 ](https://www.devexpress.com/issue=T1013688) - Refactorings - "Add Parameter" does not support implicit objection creation expressions in C# 9 [T1013883](https://www.devexpress.com/issue=T1013883) - Refactorings - "Add Setter" is available for properties with a C# 9 init accessor [T1010064](https://www.devexpress.com/issue=T1010064) - Refactorings - "Extract String to Resource" incorrectly works when extracting to an existing resource file [T1013689](https://www.devexpress.com/issue=T1013689) - Refactorings - "Reorder Parameters" does not support implicit object creation expressions in C# 9 [T1004463](https://www.devexpress.com/issue=T1004463) - Refactorings - "Sync Namespace with Folder Structure" produces a dialog about blocking user input [T1005981](https://www.devexpress.com/issue=T1005981) - Organize Members - The indent for parameters is wrongly changed
