Dotnet compilation and validation tool using execute_in_sandbox.

​
react_agent.custom_tools.dotnet_validator.DotnetValidationInput Objects

View Source Pydantic input model for specifying .NET validation parameters. Attributes:
  • source_code - The C# source code (either schema mapping or query) to compile and run.
  • framework - The specific .NET target framework (e.g., EF Core, Dapper, NHibernate).

​
react_agent.custom_tools.dotnet_validator.compile_and_run_dotnet

View Source Compile and execute C# code within an isolated Daytona Sandbox container. This complex utility performs several steps to validate .NET code:
  1. Generates the appropriate .csproj file based on the target framework.
  2. Builds a comprehensive bash script (run.sh) to compile and execute the code.
  3. Provisions environment variables and database connection strings.
  4. Base64 encodes all payload files to safely transfer them over to the sandbox.
  5. Invokes the execute_in_sandbox tool.
  6. If a query output JSON was produced, it downloads it via download_file_from_sandbox.
Arguments:
  • source_code str - The raw C# source code to compile and run.
  • framework DotnetFramework - The target .NET framework (EF Core, Dapper, etc.).
  • runtime ToolRuntime[Context, State] - The LangGraph tool runtime containing context and state.
Returns: tuple[str, str | None]: A tuple containing the standard output/error log of the execution, and the raw JSON string of the query results (if applicable and successful). Raises:
  • RuntimeError - If fetching the framework config fails or the sandbox execution throws an exception.

react_agent.custom_tools.dotnet_validator.validate_dotnet_code

View Source LangChain Tool wrapper to execute and evaluate .NET code inside a Sandbox. This tool acts as a bridge between the LangGraph state machine and the low-level sandbox execution. It calls compile_and_run_dotnet and then parses the returned JSON results. Crucially, it determines whether it is currently validating the “source” query or the “target” query based on the tool call ID or state comparison, and dynamically issues a LangGraph Command to update the global state with the parsed QueryValidationResults. Arguments:
  • source_code str - The C# source code to validate.
  • framework DotnetFramework - The target .NET framework.
  • runtime ToolRuntime[Context, State] - Automatically injected runtime context.
Returns: Command | str: A LangGraph state update command containing parsed results and the execution log, or just the error string if validation fails.
