Hello, Mark!
Last month, STS .NET 9 was released alongside LTS .NET 8. You can find more information here:

• Announcing .NET 9.
• .NET and .NET Core Support Policy

It's time to upgrade the solution to .NET 9. Are you still supporting this project?
The major concern is the lack of support for LTS .NET 8 (until November 10, 2026), as this library only supports LTS .NET 6 in its latest version 4.0.1. Additionally, Microsoft no longer supports .NET 6.

Symptoms

The Ocelot team has identified a lack of .NET 8-9 support in our CircleCI build:

• Ocelot → Branch develop → build 4663 🔴 see line 411

The build failed due to the absence of the .NET 6 SDK in our main Docker image, which only has .NET 8 and 9 preinstalled to reduce the image size. As a temporary solution, we have disabled the use of the library until the coveralls.net package supports .NET 8+9.
