Exciting ReSharper C++ 2026.2 Brings C++26 Reflection and ISPC Support

**Introduction**
JetBrains has unveiled ReSharper C++ 2026.2, the latest update to its popular Visual Studio extension for C++ developers. The release arrives amid growing excitement over the forthcoming C++26 standard, positioning the tool as an early adopter of the language’s most talked‑about feature: compile‑time reflection. In addition to reflection, the update adds experimental ISPC (Intel SPMD Program Compiler) support and introduces a new ACP (Agent‑Based Code Assistance) framework, with Junie as the first available agent.

**Key Developments**
The headline addition is preliminary support for C++26 reflection, allowing developers to query type information, enumerate members, and generate code at compile time without resorting to external libraries or macros. ReSharper now highlights reflection‑related syntax, offers quick‑fixes for common patterns, and provides navigation aids that jump between a reflected type and its generated metadata.

ISPC support brings syntax highlighting, code completion, and error detection for SPMD kernels, easing the transition for developers targeting parallel CPU workloads. The extension also ships with the ACP agent infrastructure, a plug‑in model that lets third‑party tools contribute context‑aware suggestions directly inside the editor. Junie, the inaugural agent, focuses on refactoring assistance for legacy codebases, offering automated suggestions for modernizing C++ constructs while preserving semantics.

**Industry Analysis**
Industry observers note that JetBrains’ early embrace of C++26 reflection could accelerate adoption of the new standard, particularly in performance‑critical domains such as game development, high‑frequency trading, and embedded systems. By integrating reflection awareness into a widely used productivity tool, JetBrains lowers the barrier for teams experimenting with metaprogramming techniques that were previously confined to research prototypes.

The addition of ISPC support signals a broader strategy to cater to heterogeneous computing trends. As more projects leverage SIMD and
