• Implement async/await patterns with proper cancellation
• Configure NuGet package publishing
• Support .NET Standard 2.0/2.1, .NET Core 3.1, .NET 6/7/8
• Design extension methods for fluent APIs
• Implement dependency injection patterns
• Configure XML documentation for IntelliSense
• Support source link for debugging

Target Processes

• Multi-Language SDK Strategy
• SDK Architecture Design
• SDK Testing Strategy

Integration Points

• NuGet package registry
• xUnit/NUnit for testing
• dotnet CLI for building
• HttpClientFactory for HTTP
• System.Text.Json/Newtonsoft.Json
• Polly for resilience

Input Requirements

• API specification
• Target framework versions
• Nullable reference types preference
• HTTP client preference
• Dependency injection requirements

Output Artifacts

• .NET SDK source code (.csproj)
• NuGet package specification
• xUnit test project

Usage Example

skill:
  name: csharp-sdk-specialist
  context:
    apiSpec: ./openapi.yaml
    targetFrameworks:
      - netstandard2.0
      - net6.0
      - net8.0
    nullableEnabled: true
    useSourceLink: true
    jsonSerializer: system-text-json

Best Practices

1. Use async/await with ConfigureAwait(false)
2. Support CancellationToken in all async methods
3. Implement IDisposable/IAsyncDisposable properly
4. Use nullable reference types
5. Provide extension methods for DI registration
6. Include comprehensive XML documentation
