Added net10.0 targeting to all packages and flowed RC2 dependency versions. #6995

joperezr · 2025-10-31T21:53:01Z

This will make it such that all projects will also target Net10, as well as have a different dependency group so that they flow net10 dependency versions in order to not break out of the shared framework.

Pull Request Overview

This PR adds support for .NET 10.0 target framework to the repository. The major version is updated from 9 to 10, and the existing infrastructure is extended to handle net10.0 alongside net9.0 and net8.0.

Updates the major target framework from net9.0 to net10.0, while maintaining support for net9.0 and net8.0
Adds package version definitions for .NET 10.0 RC2 dependencies from runtime and ASP.NET Core repos
Fixes conditional compilation directives to use NET9_0_OR_GREATER for broader version coverage
Updates test code to use the modern IHost/HostBuilder pattern instead of the obsolete IWebHost/WebHost APIs

@stephentoub there is a failure in MEAI.Abstraction tests. Could you take a look while I investigate the rest?

  Failed Microsoft.Extensions.AI.AIJsonUtilitiesTests.AddAIContentType_ConflictingIdentifier_ThrowsInvalidOperationException [4 ms]

I'm taking a look...

@stephentoub / @eiriktsarpalis - The AIJsonUtilitiesTests.AddAIContentType_ConflictingIdentifier_ThrowsInvalidOperationException test is behaving differently between net9.0 and net10.0. I'm still investigating, but in net10.0 it is resulting in a NotSupportedException indicatin the type has not been registered for resolution rather than the InvalidOperationException because of having been registered twice as occurs in net9.0.

I'll continue investigating Saturday.

…rovider Replace single clock.Advance/Wait uses with a polling loop that repeatedly advances the FakeTimeProvider and briefly waits to ensure ExecuteAsync's _delay_ is armed and completes across different runtimes. Add a maxAttempts guard and assertions to avoid indefinite hangs and to validate that a log record or publisher invocation actually occurred before proceeding.

…10 and skip on Windows Add NET10_0_OR_GREATER preprocessor block and apply ConditionalFact plus OSSkipCondition to avoid flaky behavior on Windows for .NET 10.

…eMonitoringServiceTests Replace NET10_0_OR_GREATER with NET10_0 so the ConditionalFact/OS skip targets .NET 10 only, and add the missing Microsoft.TestUtilities using required for OSSkipCondition. This stabilizes the RunTrackerAsync_IfProviderThrows_LogsError test behavior on .NET 10.

I fixed the JsonSerialization test.

@joperezr looks like we now have timeouts in the Microsoft.Extensions.Diagnostics.ResourceMonitoring.Test.ResourceMonitoringServiceTests.RunTrackerAsync_IfProviderThrows_LogsError test. Who can look at that?

I was trying to get this test to work but seems like a flaky test, failing different places. I'll just skip it for now and will assign it to someone on the ResourceMonitoring side so we can get this PR unblocked.
