# 什么是 Zongsoft

了解 Zongsoft 开源框架系列的组成、定位与适用场景。

Zongsoft 是面向 .NET 应用开发的一组开源框架、宿主程序与工具链。它的核心能力围绕插件化应用展开：宿主程序只负责建立运行环境，业务能力通过插件、配置、数据映射和附属资源部署到宿主中。

## 组成部分

### Framework

[`Zongsoft/framework`](https://github.com/Zongsoft/framework) 是框架代码仓库，包含[核心类库](https://github.com/Zongsoft/framework/tree/main/Zongsoft.Core)、插件框架、数据引擎、Web 基础库、安全、诊断、消息队列、自动升级和第三方服务适配。

### Hosting

[`Zongsoft/hosting`](https://github.com/Zongsoft/hosting) 提供终端、后台服务和 Web 三类宿主程序。宿主程序本身不承载业务逻辑，它们通过插件框架加载 `plugins/` 目录中的插件文件来组成应用。

### Tools

[`Zongsoft/tools`](https://github.com/Zongsoft/tools) 提供部署和打包工具，包括 `dotnet-deploy`、`dotnet-pack` 和正则表达式 GUI 工具。自动升级打包器 `dotnet-upgrade` 位于 framework 仓库的 `upgrading/tool` 目录。

## 适用场景

Zongsoft 更适合需要长期演进、模块边界清晰、部署形态多样的业务系统。例如：

* 多业务模块组合的后台服务。
* 需要按站点、环境、客户或部署方案组合功能的大型应用。
* 需要将通用能力沉淀为插件并跨项目复用的系统。
* 需要部署、安装包和自动升级流程配套的 .NET 应用。

## 与常见框架的关系

Zongsoft 与 [ABP](https://abp.io) 一样属于偏完整应用框架与工具链的体系，但它的组织重心更偏向“插件式应用运行时”。阅读本文档时，可以先把 Zongsoft 理解为：

1. 一套基础开发抽象。
2. 一套插件化应用模型。
3. 一套宿主程序模板。
4. 一套部署、打包和升级工具。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zongsoft.com/overview/what-is-zongsoft.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
