Aspire 9.0.0 targeting net8.0 forces .NET 9.0.0 library dependencies

[paulomorgado]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Aspire 9 Test Project (xUnit) imposes STS libraries on solutions using LTS libraries by taking a dependency on Microsoft.Extensions.Http.Resilience (>= 9.0.0).

That will force a lot of essential dependencies on 9.0.0.

Expected Behavior

Aspire 9 Test Project (xUnit) does not impose STS libraries on solutions using LTS libraries.

Steps To Reproduce

Create an Aspire 9 Test Project (xUnit) targeting net8.0 on a solution with all projects targeting net8.0 (or bellow) with central package management with version override disabled.

Exceptions (if any)

The majority of the 9.0.0 libraries still have a net8.0 target (including Microsoft.Extensions.Http.Resilience referenced)?

With an STS support policy instead of an LTS support policy.

Right, but you're aware of the Aspire support policy? Which is that it's not supported as soon as a new version is released?

I am very aware of Microsoft support policies.

And Aspire is forcing STS libraries on a solution that must use only LTS libraries.
