It's open-source under the MIT License. ## Decision facts: agent-framework - **Requirements:** Python version 3.6 or newer is required for Python installations.; The .NET Core SDK must be installed for utilizing the .NET packages. - **Adopt for:** The agent-framework provides tools for developers to build and deploy AI agents and multi-agent workflows in Python and .NET environments. ## Choose when ### Choose workflow-core if… - workflow-core is primarily C#; agent-framework is Python. - Tags unique to workflow-core: hacktoberfest, saga, saga-transactions, workflow. - When you are developing applications in the .NET ecosystem and require a simple yet powerful way to manage business processes with state tracking ### Choose agent-framework if… - agent-framework is primarily Python; workflow-core is C#. - Requirements: Python version 3.6 or newer is required for Python installations.; The .NET Core SDK must be installed for utilizing the .NET packages.. - Tags unique to agent-framework: agent-framework, agentic-ai, agents, multi-agent. - Also covers AI Agents. - Choose agent-framework if your project requires support for both Python and .NET, allowing you to develop across different ecosystems. ## When NOT to use workflow-core - If your project requires integration with non-.NET technologies for workflow management - When complex workflows and extensive customization options are needed that exceed the capabilities of a lightweight library like workflow-core ## When NOT to use agent-framework - Avoid using the agent-framework if your team does not have proficiency in either Python or.NET, as this may cause difficulties in leveraging its features effectively. - Do not opt for agent-framework if you only need lightweight support for AI agents without a comprehensive orchestration and deployment framework. ## Common questions ### What is the difference between workflow-core and agent-framework? workflow-core: Lightweight workflow engine for .NET Standard. agent-framework: Framework for building and deploying AI agents and multi-agent workflows. See the comparison table for live GitHub stats and shared categories. ### When should I choose workflow-core over agent-framework? Choose workflow-core over agent-framework when workflow-core is primarily C#; agent-framework is Python; Tags unique to workflow-core: hacktoberfest, saga, saga-transactions, workflow; When you are developing applications in the .NET ecosystem and require a simple yet powerful way to manage business processes with state tracking. ### When should I choose agent-framework over workflow-core? Choose agent-framework over workflow-core when agent-framework is primarily Python; workflow-core is C#; Requirements: Python version 3.6 or newer is required for Python installations.; The .NET Core SDK must be installed for utilizing the .NET packages.; Tags unique to agent-framework: agent-framework, agentic-ai, agents, multi-agent; Also covers AI Agents; Choose agent-framework if your project requires support for both Python and .NET, allowing you to develop across different ecosystems. ### When should I avoid workflow-core? If your project requires integration with non-.NET technologies for workflow management When complex workflows and extensive customization options are needed that exceed the capabilities of a lightweight library like workflow-core ### When should I avoid agent-framework? Avoid using the agent-framework if your team does not have proficiency in either Python or.NET, as this may cause difficulties in leveraging its features effectively. Do not opt for agent-framework if you only need lightweight support for AI agents without a comprehensive orchestration and deployment framework. ### Is workflow-core or agent-framework more popular on GitHub? agent-framework has more GitHub stars (13,573 vs 5,924). Stars measure visibility, not whether either tool fits your constraints. ### Are workflow-core and agent-framework open source? Yes - both are open-source projects on GitHub (workflow-core: MIT, agent-framework: MIT). ### Where can I find alternatives to workflow-core or agent-framework? GraphCanon lists graph-backed alternatives at [workflow-core alternatives](/tools/danielgerlag-workflow-core/alternatives) and [agent-framework alternatives](/tools/microsoft-agent-framework/alternatives) ([workflow-core markdown twin](/tools/danielgerlag-workflow-core/alternatives.md), [agent-framework markdown twin](/tools/microsoft-agent-framework/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/danielgerlag-workflow-core-vs-microsoft-agent-framework.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, workflow-core or agent-framework? workflow-core: Very active. agent-framework: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for workflow-core and agent-framework? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [workflow-core trust report](/tools/danielgerlag-workflow-core/trust); [agent-framework trust report](/tools/microsoft-agent-framework/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=danielgerlag-workflow-core`](/api/graphcanon/graph?tool=danielgerlag-workflow-core) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
