Upgrade to .NET 10.0, C# 14, and latest NuGet packages

[Copilot]

Upgrades all projects to .NET 10.0 and C# 14, updates NuGet packages to latest versions, and implements breaking API changes.

Framework & Language

• Target framework: net9.0 → net10.0
• Language version: C# 12 → 14

Package Updates

Major version bumps:

• ASP.NET Core & EF Core: 8.0.x/9.0.x → 10.0.2
• Semantic Kernel: 1.60.0 → 1.70.0
• ModelContextProtocol: 0.3.0-preview.4 → 0.8.0-preview.1
• CodeAnalysis: 4.8.0 → 5.0.0
• OAuth.GitHub: 9.4.1 → 10.0.0
• DotnetSitemapGenerator: 1.0.4 → 2.0.0

Breaking Changes Addressed

ModelContextProtocol API

// Before
IMcpClient? mcpClient;
await foreach (McpClientTool tool in mcpClient.EnumerateToolsAsync(...))

// After  
McpClient? mcpClient;
var tools = await mcpClient.ListToolsAsync(...);
foreach (McpClientTool tool in tools)

Updated ResponseTool.CreateFunctionTool() signature to include required strictModeEnabled parameter.

ASP.NET Core Deprecations

• ForwardedHeadersOptions.KnownNetworks → KnownIPNetworks

EF Core 10 Multi-Provider Registration

EF Core 10 enforces single database provider per service provider. Test infrastructure updated to:

• Remove all DbContext registrations before adding test provider
• Disable DatabaseMigrationService in test environment to prevent conflicts
• Delay database initialization until after service provider is fully configured

Suppressions

• CA1873: New logging performance analyzer - extensive refactor required
• OPENAI001: Intentional use of experimental Response API

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.hcaptcha.com

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Update all aspects of this project to .net 10.0 and C# 14 using latest practices and also update the nuget packages - implementing breaking api changes. Feel free to use the nuget mcp to get latest available packages
