Optimizely Commerce 14 Now Supports .NET 10

In my previous post, Optimizely CMS 12 Now Fully Supports .NET 10, I noted one remaining limitation: Commerce 14 (Commerce Connect) did not yet support .NET 10, and Commerce customers were advised to stay on .NET 8.

I'm happy to report that this gap has now been closed. Commerce 14 officially supports .NET 10 starting with version 14.46.0. It's also mentioned in the release notes.

What's New

• EPiServer.Commerce 14.46.0 – adds official .NET 10 support.
• EPiServer.Find.Commerce 12.3.0 – supports Commerce 14 running on .NET 10.

If you're using Optimizely Search & Navigation (Find) with Commerce, upgrade both packages together to ensure full compatibility.

This means the full Optimizely stack, including both CMS 12 and Commerce 14, can now run on .NET 10.

Why Upgrade?

With .NET 8 and .NET 9 reaching end of support on November 10, 2026, .NET 10 is now the recommended target. As the current LTS release, it provides support through November 2028, along with performance improvements, security updates, and a longer support horizon.

Recommendations

• Upgrade EPiServer.Commerce to 14.46.0 or later before moving to .NET 10.
• Upgrade EPiServer.Find.Commerce to 12.3.0 or later if you use Find with Commerce.
• Verify that any additional add-ons or integrations are compatible with .NET 10.
