c# – Central Package Management not working as expected for transitive packages - Faz Business

I have projects in my solution that have the following package reference:

<PackageReference Include="System.Text.Json" />

My Directory.Packages.props contains:

<PackageVersion Include="Microsoft.Extensions.Hosting" Version="8.0.19" />
<PackageVersion Include="System.Text.Json" Version="8.0.6" />

These are the latest versions available for .NET 8.

The settings:

<PropertyGroup>
  <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally>
  <CentralPackageTransitivePinningEnabled>false</CentralPackageTransitivePinningEnabled>
</PropertyGroup>

But I am getting the following build error on each project:

Warning As Error: Detected package downgrade: System.Text.Json from 9.0.0 to 8.0.6. Reference the package directly from the project to select a different version.
MyProject -> Microsoft.Extensions.Hosting 9.0.0 -> Microsoft.Extensions.Configuration.Json 9.0.0 -> System.Text.Json (>= 9.0.0)
MyProject -> System.Text.Json (>= 8.0.6)

When I set CentralPackageTransitivePinningEnabled to true, the only project that does not need to reference Microsoft.Extensions.Hosting throws the error on build.

I can’t pinpoint the problem as I am not reference .NET 9 and I want to stick with .NET 8 for now. What am I missing?
