What’s new in ReSharper Ultimate 2019.2

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.

You asked and we delivered: the context action Convert concatenation to interpolation can now be applied in scope.

Borrowing from Rider, we’ve started using the MSBuild-based project model instead of the Visual Studio COM API. This will help optimize solution loading times as we’ve minimized the use of COM API, which locks the UI thread.

In addition, we’ve updated the Performance Guide page. It has a new Windows Defender section and descriptions for all performance tips, which describe what exactly will be done after a suggestion is applied.

In this release, Find Usages starts using the data from Solution Wide Error Analysis to gather the results. If you enable SWEA for your solution, Find Usage will show you results significantly faster.

We’ve added a couple of small improvements to Navigation and hope you will find them useful: 

• You can search in a file right through the “Go to File Member” dialog. The list of results will have the names of all matching members and all the places where the search string appears in the file.
• In the Go To Text results window, you can now filter out the comment lines if you are not interested in looking for occurrences in comment strings.

ReSharper 2019.2 brings several updates to the debugger data tips:

• We’ve added a couple of new toggles: implicit function evaluation and auto evaluate property.
• They respect the setting “Enable property evaluation and other implicit function calls” and can evaluate property values on demand.

• Parameter name hints have performance improvements and new heuristics.
• A new tooltip with the keyword description is available in the IL Viewer.
• The Advanced symbols options dialog under ReSharper | Options | Tools | External Sources now supports relative paths.
• The Assembly Explorer tool window now has a ‘Summary’ property on the “Properties” tab and an unmanaged (win32) resources subtree.

In the previous release, we began to work towards better support for UE4-specific Remote Procedure Calls. Now, we've updated the Rename and Change Signature refactorings to work correctly on RPC functions. A few new code analysis checks are also available for UE4-based code, especially targeting the missing or incorrectly set UE4 reflection macros.

Following on from adding code completion for reflection specifiers in v2019.1, we've now added built-in documentation for them. It is shown in the Quick Documentation popup (Ctrl+Q) when the caret is located on a specifier.

dotMemory 2019.2 stops supporting remote profiling. To offer you an adequate replacement, we significantly improved the dotMemory console profiler:

• The console profiler gets commands to profile all types of applications including .NET Core applications, IIS Express-hosted applications, Windows services, and others.
• The --trigger-on-activation argument allows taking a memory snapshot right after this becomes possible. This feature can be helpful in case you want to take a baseline snapshot and use it for comparison.
