[ncipollina]

Summary

• Added .NET 10.0 target framework support to all projects (core library, observability package, and tests)
• Split NuGet package dependencies by framework version to ensure each framework uses appropriate package versions
• Updated AWS SDK and test dependencies to latest stable versions
• Bumped package version to 1.2.2

Changes

Framework Support

• Added net10.0 to TargetFrameworks in all projects
• Core library now targets: .NET 8.0, 9.0, and 10.0
• Observability package now targets: .NET 8.0, 9.0, and 10.0
• Test project now targets: .NET 8.0, 9.0, and 10.0

Package Dependencies (Framework-Specific)

Core Library:

• .NET 8.0: Uses Microsoft.Extensions v8.x packages
• .NET 9.0: Uses Microsoft.Extensions v9.x packages
• .NET 10.0: Uses Microsoft.Extensions v10.0-rc.2 packages
• Updated AWS SDK packages (shared across all frameworks):
  • AWSSDK.DynamoDBv2: 4.0.5.1 → 4.0.8.1
  • AWSSDK.Extensions.NETCore.Setup: 4.0.2.2 → 4.0.3.7

Observability Package:

• Updated OpenTelemetry: 1.12.0 → 1.13.1

Test Project:

• .NET 8.0: Uses Microsoft.Extensions.Configuration v8.x
• .NET 9.0: Uses Microsoft.Extensions.Configuration v9.x
• .NET 10.0: Uses Microsoft.Extensions.Configuration v10.0-rc.2
• Updated test dependencies:
  • AwesomeAssertions: 9.1.0 → 9.2.1
  • xunit.v3: 3.0.1 → 3.1.0
  • xunit.runner.visualstudio: 3.1.4 → 3.1.5
  • Microsoft.Extensions.Diagnostics.Testing: 9.8.0 → 9.10.0

Version

• Bumped package version from 1.2.1 to 1.2.2

Test Plan

• Verify builds successfully for all target frameworks (.NET 8, 9, and 10)
• Run tests on all target frameworks to ensure compatibility
• Verify NuGet package generation includes all frameworks
• Test dependency resolution for each framework version
