Rider 2019.2

Debugger improvements

• The "Variables" tab has a new feature called 'Pin to Top'. Use it to star any of an object’s properties or fields you are most interested in, to keep them at the top of the list. 
• The "'Run to Statement"’ and "Jump to Statement" actions now have icons following the cursor in the editor.
• Added many performance improvements for stack calculation and stepping.

Xamarin support

• Adds ability to publish an '.ipa' (iOS App Store Package) file for a Xamarin iOS project to an iOS device right from the IDE.
  Select an iOS project in the Solution Explorer View, call the context menu, and click on "Archive for Publish" item.
• Manage provisioning profiles from the Properties window (Configurations | Bundle Signing) for a Xamarin iOS project.

Windows Forms designer

• Adds support for third-party controls from Telerik, DevExpress, Syncfusion, ComponentOne, and Infragistics. You can load a suite of controls into the Designer Toolbox, and then use them in the application’s forms and user controls.
  Please note that some DevExpress controls that heavily use Visual Studio API won’t work, JetBrains are currently working on a workaround.
• Adds support for 32-bit controls, so now you can use your 32-bit components in the designer.

Code coverage of Mono applications and unit tests

• In addition to coverage analysis of .NET Core applications and tests, JetBrains added support for the Mono Framework.
• Cover your .NET Framework unit tests using the Mono runtime on Linux, macOS, and Windows.

Enhanced C# support

• Take full advantage of C# 8 with ReSharper’s enhanced support:
  • Supports the latest changes in 'indices' and 'ranges' such as 'indexable' and 'rangeable' types.
  • The context action 'Add range check' now supports indexing by 'System.Index' / 'System.Range' and produces correct checks.
  • Supports 'unmanaged generic structs'.
  • Two new inspections, 'Convert switch statement to switch expression' and ‘Convert chain of ternary expressions to switch expression’, with a corresponding ‘Convert to switch expression’ quick-fix.
  • The context action 'Convert concatenation to interpolation' can now be applied in scope.

F# support

• 'Code Vision' comes to F#! - it shows you inferred types for functions, values, and members, and VCS author for declarations, right in the code editor.
• Other changes include:
  • ReSharper’s spell-checker now works for F# symbol declarations, strings, and comments.
  • Escape sequences are highlighted in strings.
  • Better highlighting is available for never-matched rules in match expressions.
  • 'Find Usages' and 'Go to Declaration' work for 'record construction' and 'copy-and-update'expressions.
  • The 'New Instance' kind of occurrences is shown for expressions that create exceptions.
  • F# Interactive can be run from .NET Core SDK 2.2.300+.

UI update

• The editor and debugger tabs in the Light themes have been redesigned to align with the 'Darcula/Dark' themes.
• The UI of the code completion popup is now clearer and more consistent, and provides better highlighting on selection in the 'Light' theme.
• Adds ability to commit directly from the 'Local Changes', so there is no longer any need to go through a separate Commit dialog.

Solution Explorer

• The Solution Explorer view adds a few updates:
  • Solution folders can now be renamed.
  • “'Auto-scroll to source'” is disabled for solution/project files.
  • 'Filtered solutions' ('*.slnf') introduced in Visual Studio 2019 can be opened in Rider.

NuGet support

• Rider 2019.2 delivers lots of updates for the built-in NuGet client:
  • It displays a package’s readme.txt to help determine the next steps after installing a package.
  • When XDT transformations are run, entries are automatically added/removed from configuration files when required by the package.
  • Rider supports native cross-platform credential providers, such as the one available for Azure DevOps/Artifacts, for accessing private feeds.

  • File Layout patterns can be modified via the XAML View (with code completion and code highlighting) right in Rider’s Settings/Preferences: Editor | Code Style | C# | File Layout.

ASP.NET support

• Implements JetBrains' ‘'ASP.NET code-behind files'’ generator for 'aspx/ascx' files.
• Now, when you add a new control to an '.aspx' file and access it from the code-behind ('.aspx.cs'), the generator creates the corresponding '.designer.cs' file.
