ReSharper C++ 2022.1 brings a brand new way to quickly consult the Unreal Engine documentation about the details of a class, symbol, or function. You can now click Read more in the Quick Documentation pop-up (Ctrl+Shift+F1) to open the corresponding page in your browser.
The Rename refactoring now handles the Unreal Engine interface classes
better. When renaming interfaces, both the
classes will be renamed accordingly.
ReSharper C++ can now substitute the parameter names when you generate a member function signature from the Unreal Engine delegate.
You can now also generate such functions when the
ThisClass typedef is used.
Here is a short overview of the most important Unreal-related fixes delivered in this version:
.Target.csfiles on Unreal Engine 4.
MARK_PROPERTY_DIRTY_FROM_NAMEpush model macros – ReSharper C++ now is aware of entities generated by the replication system, such as
The Unreal Engine testing framework is now supported. ReSharper C++ discovers Unreal Engine unit tests and adds the corresponding action indicators next to each test in the editor to run or debug the test or the whole test suite. In the Unit Test Sessions window, you can review the results of the tests, and rerun failed, all, or specific tests.
The new version of the Catch2 unit test framework brings significant changes – it’s now split into multiple headers and has a statically compiled library as its distribution model. It means you now have to include several headers, but the compilation time is improved. So if you’d like to check out the updated Catch2 unit test framework, ReSharper C++ 2022.1 has full support to help you with it.
ReSharper C++ 2022.1 also includes updates for the latest releases of GoogleTest and doctest, as well as various unit testing fixes.
ReSharper C++ is now better at handling implicit constructor calls, allowing you to find usages and navigate to the called constructor in more cases, including the following:
make_unique/make_shared) and Unreal-specific (
MakeShared/MakeUnique) smart pointer creation functions.
emplace-like container methods.
static_castand c-style cast expressions.
ReSharper C++ now also shows you an overloading
warning when an
emplace-like function is called with incorrect arguments.
ReSharper C++ 2022.1 improves the multiline generation of boilerplate code for aggregate initialization using C++20 designated initializers. You can now invoke completion on the next line if you’d like to see each initializer on a new line.
ReSharper C++ now treats the C++20
requires-expressions correctly, allowing you to configure spaces
formatting via the Around ‘->’ in trailing return types option.
Use the new Line feed at the end of file option to control adding or removing a blank line from the end of files.

ReSharper C++ now supports the new Visual Studio 2022 release build, meaning you will have access to the same rich feature set you are used to using in other Visual Studio versions. Since Visual Studio 2022 is an x64 process, there is no longer a limit to the maximum amount of memory that can be allocated to it, and all the ReSharper С++ features work faster.
To work with ReSharper C++ in Visual Studio 2022, make sure that the VS2022 icon in the dotUltimate 2021.3 installer is selected.
You can use C++20 designated initializers to quickly generate boilerplate code for aggregate initialization (P0329). Just select the corresponding item from the completion list to insert designators for the data members, and then provide the initial values.
With the C++20
contains function, you can easily check whether an element exists
in an associative container
(P0458). A new inspection suggests replacing instances of
count with the new
contains member function.
The new standard brings convenient library functions for erasing elements that work
for all standard containers
A dedicated inspection will let you know when an erase-remove idiom can be replaced
Another new library addition is the smart pointer creation functions that perform
When you need to allocate an array of built-in types and then immediately initialize
it, you can now apply a quick-fix to use
With ReSharper C++ 2021.3, you no longer need to switch to Unreal Editor to create a new class – all predefined templates for Unreal Engine classes are now available in the list of ReSharper file templates.
To create a new class, go to Solution Explorer and right-click on the preferred project folder to open the Add menu (or use Ctrl+Alt+Insert). After you choose an Unreal Engine template from the list and give your new class a name, ReSharper C++ will generate the header and source files with the template code in the proper folders depending on whether the folder is private or public.
We’ve fixed an issue that would sometimes cause ReSharper to reindex source code when a solution was loading.
A new inspection marks redundant parentheses in lambdas with no parameters, since a parameter list is not required in such cases.
When an elaborated type specifier is used neither to declare a new class nor to refer to a previously declared but hidden class, ReSharper C++ will suggest removing the specifier.
A new inspection finds
for loops that can be written in a more concise
while loops. The accompanying quick-fix lets you quickly rewrite
User specializations of classes like
are often wrapped in a standalone namespace. To make your code more readable,
ReSharper C++ suggests using a qualified class name instead.
If you construct an object of an exception type but do not use it,
ReSharper C++ now warns you and lets you quickly
The Quick Info tooltip now includes the evaluation results for constant
expressions. You can use this feature to see what subexpressions of a failing
static_assert expression evaluate to, or to check out the value of
In addition to the Document action (via the Alt+Enter menu or the
Ctrl+/ shortcut), you can now generate a stub for a new documentation
comment by typing
/// before a function or another entity you want to document.
The File Structure window now groups symbols with the same qualifier. This is especially useful in source files that contain a lot of out-of-class functions.
ReSharper C++ 2021.3 allows you to search for declarations in inactive code, where navigation was previously not available.
You can also now navigate from a
goto statement to the corresponding label.
The Change Signature refactoring now lets you easily control the
[[nodiscard]] attribute, which indicates that the function
caller should use the function’s return value.
ReSharper C++’s 2021.3 supports C11
expressions, which provide a mechanism for limited compile-time choices in C.
Take a look at What's New in ReSharper to learn about the other changes introduced in this release. For example, additional GitHub-related items in the Copy Code Reference pop-up make it easy to share links with people, and you can also add a custom URI template for non-GitHub repositories.
New inlay hints make hidden type conversions visible in the editor, so that you are aware of their potential performance and correctness implications.
You will see special icons for implicit conversions. Alternatively, you can choose to show the conversions as textual hints.
ReSharper C++ displays hints for different kinds of class type conversions, including object copying, object initialization using converting constructors or aggregate initialization, and calls to conversion operators.
You can also enable hints for standard conversions between built-in types, for example, conversions between numeric types that might lose precision or change the signedness of the type.
Immutability-related analyses can help you keep your code more readable and correct. By adding two new inspections, ReSharper C++ now covers all the rules from the Constants and immutability section of the C++ Core Guidelines.
The first new inspection extends the immutability analysis for function parameters
of reference and pointer types. ReSharper C++ will notify
you if you can pass a pointer or a reference to
const, which guarantees that the
function will not modify the corresponding function argument.
The second inspection suggests marking variables that can be evaluated at
constexpr, which can lead to faster performance and
better compile-time checking.
ReSharper C++ 2021.2 includes some new inspections to help you modernize your code.
Structured binding can be used instead of tie(..): since C++17, you no longer
need to use
boost::tie() for unpacking a tuple
or a pair – structured binding declarations help you simplify your code.
Type trait can be simplified using a template alias or a variable template: C++14 alias templates let you shorten C++11 type trait expressions.
std::size can be used: this inspection suggests using
as a type-safe alternative to the error-prone C idiom for array size calculation.
Zero initialization can be used instead of memset: zero-initialization leads
to more concise code and prevents various
The new Inline Function refactoring lets you quickly replace a function call with the body of the function. To invoke it, place the caret on a function call and select Inline Function from the Refactor This menu, or choose ReSharper | Refactor | Inline from the main menu. ReSharper C++ will perform the necessary transformations, handle all the name conflicts, and reformat the resulting code.
By default, ReSharper C++ generates functions with empty bodies, but now you can
specify whether the generated functions should throw an
return a default value, or include uncompilable code. To configure this, go to
ReSharper | Options | Code Editing | C++ | Code Generation.
ReSharper C++ will also automatically call the base function
from the body of an overriding function.
A new context action lets you convert any string into a C++11 raw string literal, which is easier to read when the string literal contains special characters. The transformation works both ways, so you can convert a raw string literal into a regular string literal, too.
If you want to quickly consult cppreference.com about the details of a standard library class or function, you can now click Read more in the Quick Documentation pop-up (Ctrl+Shift+F1) to open the corresponding page in your browser.
When you press Backspace on an empty line or a line with whitespaces or tabs to the left of the caret, ReSharper C++ can now place the caret at the proper indent position instead of moving it back one position at a time.
ReSharper C++ 2021.2 supports working with Unreal Engine 5 from both the Unreal Launcher and GitHub sources.
In the .Build.cs and .Target.cs files of an Unreal Engine project, ReSharper C++’s code completion now suggests the list of available modules and plugins.
After you’ve added a module or a plugin, the new inspection for missing dependencies will highlight any that must be referenced in the .uproject or .uplugin file. Use the accompanying quick-fix to add new modules and plugins to the project files with a single click.
When generating a definition of an overriding function,
ReSharper C++ will now call the overridden function
from the generated body using the idiomatic
Super type alias.
We've improved the performance and memory usage of a cold startup. Now ReSharper C++ indexes the Unreal Engine codebase 10% faster.
The bundled Clang-Tidy has been updated to Clang 12, adding new checks from the latest LLVM release. We’ve also improved its performance in complex files, particularly in C++20 projects.
A new inspection warns you when you compare an unsigned expression with 0, which may cause an infinite loop or unreachable code.
Take a look at What's New in ReSharper to learn about the other changes coming to the ReSharper platform. For example, the InspectCode command line tool now restores NuGet packages and builds a solution before starting its analysis.
