Pull request overview

Updates the repository to build and test against newer .NET/EF Core versions by introducing centralized build/test configuration and package version management, and aligning tests/samples with updated APIs.

Changes:

• Multi-targets projects to net8.0;net9.0;net10.0, adds global.json, and centralizes package versions in Directory.Packages.props.
• Simplifies test project .csproj files by moving common test settings/references into test/Directory.Build.props.
• Updates tests and samples to newer xUnit assertions and async trigger interfaces/overloads.

test/EntityFrameworkCore.Triggered.Tests/EntityFrameworkCore.Triggered.Tests.csproj:1

• With test/Directory.Build.props adding a ProjectReference to EntityFrameworkCore.Triggered, this explicit ProjectReference can become a duplicate once the props path is corrected. Duplicated ProjectReference items can lead to noisy builds (duplicate item warnings) and makes dependencies harder to reason about. Prefer defining this reference in only one place: either remove it here and keep it centralized in test/Directory.Build.props, or remove the centralized reference and keep per-project references (or conditionally include it only for projects that need it).

The ProjectReference path is incorrect relative to test/Directory.Build.props. From the test folder, ..\\..\\src\\... resolves outside the repository and will fail to resolve the project. Change it to ..\\src\\EntityFrameworkCore.Triggered\\EntityFrameworkCore.Triggered.csproj.
