CrestApps.Core

CrestApps.Core is a composable AI management and application framework for .NET. It is designed for teams that want to add advanced AI capabilities to an existing application without spending months rebuilding orchestration, chat, retrieval, reporting, and integration plumbing from scratch.

What it delivers​

  • provider-agnostic AI management with connections, deployments, agent profiles, and data sources
  • reusable AI agent profiles that define behavior, prompts, models, tools, and defaults
  • chat interactions for playground and production scenarios
  • document upload and processing for Q&A, summarization, extraction, and tabulation
  • RAG across search indexes, attached files, and user memory
  • AI agents, MCP, A2A, and remote host integration
  • custom AI functions and deep runtime extensibility
  • chat metrics, reporting, lead workflows, post-session processing, and live-agent handoff
