As an end-of-support product, .NET Framework 4.6.2 no longer receives new security patches. However, during its lifecycle, it received several critical updates.

A highly anticipated change was the removal of the legacy 260-character path length limitation ( MAX_PATH ) in System.IO APIs, a long-standing source of errors for applications dealing with deeply nested file structures.

While older versions of Visual Studio used it extensively, users in Visual Studio 2022

Desktop application developers received critical infrastructure updates in WPF:

Unlike major version jumps (from 4.5 to 4.8), 4.6.2 was an in-place update to the 4.x series. This means it respects the “same major version” rule: applications built for 4.0, 4.5, 4.5.1, 4.5.2, 4.6, or 4.6.1 can run on 4.6.2 without recompilation — provided they don’t rely on removed or altered APIs (which were very rare). This backward compatibility is its superpower.

The release introduced a new 64-bit Just-In-Time (JIT) compiler (RyuJIT) which, in some cases, caused runtime exceptions. Known issues included:

Don't rush to rewrite a stable app just because it's on .NET Framework 4.6.2 – it's still secure, reliable, and supported. But do plan a migration to modern .NET for new features and long-term agility. Only required for existing apps on a machine

If you’re still developing or deploying on 4.6.2 today, consider moving to (the drop-in replacement) or migrating to .NET 6/8 (LTS, cross-platform). Why?

If full migration to modern cross-platform .NET is restricted by deep dependencies on Windows-specific technologies (like WCF server or workflow foundation), the safest immediate step is upgrading the target framework to . This requires minimal code changes, preserves full backward compatibility, and extends the support runway significantly.

As a component of the Windows operating system, .NET Framework v4.6.2 follows the lifecycle policy of the underlying OS on which it is installed.
