feat: support .NET 10 and removed .NET6, 7

[arika0093]

This pull request updates the project to support .NET 10 and removes support for .NET 6 and 7. It updates the SDK and package dependencies accordingly, ensures all workflows use the latest .NET versions, and revises the sample and library projects to target .NET 10. The lock file is regenerated to reflect these changes and to update transitive dependencies.

.NET Version and SDK Updates:

• Updated all GitHub Actions workflows (release.yaml, release-github.yaml, test.yaml, sample-deploy.yaml) to use .NET 10.x and dropped support for .NET 6.x and 7.x. The sample deploy workflow also updates the setup-dotnet action to v4 and targets 10.0.x. [1] [2] [3] [4]

• Changed the target framework of the sample project (BlazorLocalTimeSample.csproj) to net10.0.

Library Project and Dependency Management:

• Updated BlazorLocalTime.csproj to target only .NET 8, 9, and 10 (removing 6 and 7), and added a new item group for .NET 10 package references. [1] [2]

• Regenerated packages.lock.json to remove .NET 6 and 7 dependencies, add .NET 10 dependencies, and update transitive dependencies to their latest versions, including Nerdbank.GitVersioning and others. [1] [2] [3]

Walkthrough

The changes upgrade .NET targets and SDKs across workflows and projects to include 10.x/net10.0, remove net6/net7, and adjust dependencies accordingly. Test infrastructure updates include relaxed package ranges and modified Public API approval generation to exclude assembly attributes and drop framework-version discriminators.

Poem

I thump my paw—new tens arrive, hurrah!
Pipelines hop to fresher SDK straw.
APIs trimmed, approvals neat,
RC carrots make builds sweet.
With nets re-spun and tests in line,
I nibble bytes—release on time. 🥕🐇

🔇 Additional comments (10)

example/BlazorLocalTimeSample/BlazorLocalTimeSample.csproj (1)

3-3: Verify .NET 9 packages work with net10.0 target.

The sample project targets net10.0 but references .NET 9.x packages (Microsoft.AspNetCore.Components.WebAssembly 9.0.4 and DevServer 9.0.9). While this is typically acceptable during the .NET 10 RC period, confirm these packages are compatible with the net10.0 target framework to avoid runtime issues.

Also applies to: 9-12

tests/Directory.Build.props (1)

10-13: LGTM! Wildcard versions reduce lock file churn.

Relaxing test dependency version constraints to wildcards (17., 1., 3.*) is appropriate for test projects and reduces maintenance overhead when supporting multiple target frameworks.

src/BlazorLocalTime/BlazorLocalTime.csproj (2)

3-3: LGTM! Target framework update aligns with PR objectives.

The removal of net6.0 and net7.0 and addition of net10.0 correctly implements the stated PR goals. Supporting net8.0, net9.0, and net10.0 provides appropriate coverage for a library.

---

22-28: Confirm RC packages for net10.0 target

net10.0 group references RC packages (10.0.0-rc.1, go-live; GA on Nov 11 2025); ensure publishing a library with pre-GA dependencies aligns with your release policy or consider waiting for the final release.

tests/BlazorLocalTimeTest/PublicApiCheckTest.cs (2)

13-19: LGTM! Excluding assembly attributes improves multi-TFM testing.

Setting IncludeAssemblyAttributes = false removes framework-specific metadata from the public API surface, which simplifies approval file maintenance when testing across net8.0, net9.0, and net10.0.

---

20-25: LGTM! Removing version discriminator consolidates approval files.

Dropping the framework-version discriminator from approval file naming consolidates multiple per-TFM approval files into a single file. This reduces maintenance overhead and is appropriate when the public API surface is identical across target frameworks.

tests/BlazorLocalTimeTest/Approvals/PublicApiCheckTest.Run.approved.txt (1)

1-115: LGTM! Approval file correctly reflects assembly attribute exclusion.

The removal of assembly metadata (RepositoryUrl, InternalsVisibleTo, TargetFramework) aligns with the IncludeAssemblyAttributes = false setting in PublicApiCheckTest.cs. The public API surface remains intact and unchanged.

tests/BlazorLocalTimeTest.Nls/BlazorLocalTimeTest.Nls.csproj (1)

3-3: LGTM! Test coverage extended to net10.0.

Adding net10.0 to the target frameworks ensures NLS-specific tests run against all supported .NET versions, consistent with other test projects in the solution.

.github/workflows/test.yaml (1)

27-30: LGTM! CI matrix updated for .NET 10 testing.

Adding 10.x to the dotnet-version matrix ensures tests run against all supported framework versions (8.x, 9.x, 10.x) across all target operating systems, aligning with the project's multi-TFM strategy.

.github/workflows/sample-deploy.yaml (1)

22-24: LGTM! Deployment workflow updated for .NET 10.

Upgrading to actions/setup-dotnet@v4 and targeting 10.0.x correctly aligns the deployment workflow with the sample project's net10.0 target framework.
