C# Runner FAQs

Question 1

What is C# Runner and its primary purpose?

Accepted Answer

C# Runner is a high-performance and secure platform designed for executing C# code online. Its primary purpose is to provide a safe, isolated environment for running untrusted C# code with features like containerization and resource limits.

Question 2

What are the key performance benefits of C# Runner?

Accepted Answer

C# Runner offers high performance via worker warm-up (pre-compiling code), intelligent load balancing across multiple workers using a Round-Robin algorithm, and efficient connection pooling to minimize overhead and ensure fast execution.

Question 3

Does C# Runner support real-time output streaming?

Accepted Answer

Yes, C# Runner supports real-time streaming of code output, results, and errors. This is achieved using Server-Sent Events (SSE) through its HTTP REST API, providing immediate feedback during code execution.

Question 4

What APIs and protocols does C# Runner support?

Accepted Answer

C# Runner provides a flexible HTTP REST API for common use cases, along with support for the Model Context Protocol (MCP) for more advanced integrations. Both protocols enable robust interaction with the execution environment.

Question 5

How does C# Runner ensure secure code execution?

Accepted Answer

Security is maintained through robust container isolation using Docker, configurable resource limits (CPU, memory, timeout), network isolation for worker containers, and automatic recycling of worker instances to prevent environment contamination.
