Checklist [✔ ] I've read the Contributing Guidelines and the Code of Conduct [ ✔] I've completed the Contributor License Agreement Pull Request Details This PR adds C# language support to the Facebook Business SDK Codegen, enabling automatic generation of the C# SDK for the Facebook Marketing API. Changes New C# Language Support CodeGenLanguageCs.js: Language processor with C# type mappings and code generation logic C# Templates (): : Main template for API object classes : API context configuration with template variables : Base class for API resources : HTTP request handling with proper error handling : Configuration constants : .NET project file Configuration Updates : Added C# version detection : Added 'csharp' to supported languages : Registered C# processor : Updated to reflect 6 language support Critical Bug Fix SpecOverridingProcessor.js**: Fixed jsonpath-plus v10.3.0 breaking change This fix unblocks code generation for ALL languages (Java, Python, Node.js, Ruby, PHP) API Request Improvements Added explicit PUT HTTP method handling (was incorrectly defaulting to GET) Added JsonException catching for deserialization errors Consistent exception handling through APIException wrapper Source Code Restoration Restored directory for language extensibility All source files rebuilt to via At the same time, the build is present here - https://github.com/BranislavMateas/facebook-business-sdk-dotnet Test Plan Test Plan 1. Codegen Execution [ ] Run successfully [ ] Execute generates 952 C# classes without errors [ ] All files generated in correct structure: 2. Generated Code Validation [ ] APIContext.cs uses dynamic template variable [ ] APIConfig.cs contains correct API version, base URLs, and user agent [ ] APIRequest.cs properly handles GET, POST, PUT, and DELETE methods [ ] Exception handling catches HttpRequestException and JsonException [ ] Generated code follows C# naming conventions 3. Configuration Verification [ ] has csharp entry pointing to correct version file [ ] includes 'csharp' in supported languages [ ] registers C# processor [ ] Version detection reads from FacebookBusinessSDK.csproj 4. Bug Fix Verification [ ] jsonpath-plus v10.3.0 fix works (SpecOverridingProcessor.js uses new API) [ ] All languages still generate without errors: Java, Python, Node.js, Ruby, PHP 5. Generated SDK Repository [ ] Generated C# SDK is available at: https://github.com/BranislavMateas/facebook-business-sdk-dotnet [ ] SDK can be built with [ ] All 952 classes compile without errors [ ] Package can be created with
