JNBridgePro v12.1 is here — and it’s built for where enterprise development is heading. This release extends proxy-based Java/.NET bridging to the latest runtimes and introduces AI-friendly examples designed to cut your configuration and implementation time dramatically.

If you’re running .NET 8, 9, or 10 alongside Java, this is the version to be on.

What’s New in v12.1

Full .NET 9 and .NET 10 Support

JNBridgePro v12.1 now supports .NET 8, 9, and 10 (the runtimes formerly known as .NET Core). Whether you’re targeting the latest LTS release (.NET 8) or running on the cutting edge with .NET 10, JNBridgePro generates proxies that work natively across all three — on both Windows and 64-bit Linux.

This matters because Microsoft’s .NET release cadence has accelerated. Annual releases mean your integration tooling needs to keep pace. With v12.1, your Java/.NET bridge stays current without migration headaches.

JDK 8 Through 25 and Jakarta EE 11

On the Java side, v12.1 supports JDK versions 8 through 25 and Java EE 8 through Jakarta EE 11. That’s full coverage from legacy Java 8 applications all the way to the latest Java release — no version gaps, no workarounds.

AI-Ready Configuration Examples

Here’s where v12.1 gets interesting for modern workflows: the release includes new examples specifically designed to be consumed by AI coding assistants. Feed them into ChatGPT, Copilot, Claude, or your team’s AI tooling, and they’ll generate accurate JNBridgePro configurations in minutes instead of hours.

This isn’t just documentation — it’s structured reference material that AI models can parse and apply. Instead of reading through setup guides, you describe what you need and let AI handle the boilerplate:

• Proxy generation configs — tell AI which Java classes you need in .NET (or vice versa), get a working configuration
• TCP/binary and shared memory setup — AI can scaffold your communication layer configuration from the examples
• Deployment patterns — common enterprise deployment scenarios, ready for AI to adapt to your specific environment

The result: faster time-to-bridge, fewer configuration errors, and less time in documentation.

Why This Release Matters

JNBridgePro has always been the fastest path from “we need Java and .NET to talk” to “it’s in production.” Generate proxies, call Java from C# (or C# from Java) with native syntax, deploy with confidence. Enterprises have trusted this approach for over two decades.

v12.1 keeps that core value proposition and brings it fully up to date:

• Current runtimes: .NET 10, JDK 25, Jakarta EE 11 — no waiting for compatibility patches
• AI acceleration: Get configured faster with examples built for how developers actually work in 2026
• Proven stability: Same proxy-based architecture trusted by financial services, healthcare, government, and Fortune 500 companies worldwide
