What's new in ReSharper 2026.2

• Junie — a multi-model agent that can execute complex tasks without leaving Visual Studio.

• dotTrace, dotMemory and dotCover integrations in Visual Studio now also work in the Out-of-Process mode.

• Extract Method refactoring now detects occurrences of the extracted logic in the same file and suggests replacing them.

• Faster, more memory-efficient processing of .cshtml and .razor files.

• New features in C++:

  • Support for C++26 language features:

    • Core reflection primitives, including the ^^ (reflect) operator, the [: ... :] (splice) syntax, and compile-time queries on reflected types, members, enumerators, and other entities.

    • consteval { ... } blocks.

    • User-defined annotations can now be attached to declarations and queried through the reflection API, enabling custom metadata-driven code generation.

    • The constexpr evaluator now supports C++26 constexpr exceptions and handles try/catch and throw expressions during constant evaluation.

  • ISPC (Intel SPMD Program Compiler) language support.

  • Unreal Engine:

    • Indexing of C++ code is up to 55% faster, and loading C++ caches from serialized data during a warm IDE startup is up to 35% faster.

    • Discovering usages of gameplay tags inside Blueprint assets and showing them in Code Vision and Find Usages results.

  • New [[jetbrains::used_implicitly]] attribute.

  • New context actions to toggle the const qualifier on a member function, insert a #pragma clang diagnostic ignored directive to suppress a specific Clang diagnostic on the current line, and copy the include path for the currently opened header file from the Copy Code Reference menu.

  • New inspections for applying internal linkage, using designated initializers in aggregate initialization, and detecting qualified calls to overridden virtual functions.
