BootstrapBlazor介绍
- 使用文档：https://www.blazor.zone/introduction
- Gitee项目地址：https://gitee.com/LongbowEnterprise/BootstrapBlazor
BootstrapBlazor是一套基于 Bootstrap 和 Blazor 的企业级组件库，可以认为是 Bootstrap 项目的 Blazor 版实现。基于 Bootstrap 样式库精心打造，并且额外增加了 100 多种常用的组件，为您快速开发项目带来非一般的感觉（喜欢Bootstrap风格的同学推荐使用）。
BootstrapBlazor类库安装
管理Nuget程序包=>搜索BootstrapBlazor进行安装。
BootstrapBlazor库注入容器
在Program.cs中将 BootstrapBlazor 库添加到 ASP.NET Core 项目中的依赖关系注入容器中。
导入BootstrapBlazor组件库命名空间
打开_Imports.razor文件，导入BootstrapBlazor组件库命名空间：@using BootstrapBlazor.Components。
Menu 导航菜单设置

<h2>七天.NET 8操作SQLite入门到实战详细教程</h2>
<h5>SQLite是一个轻量级的嵌入式关系型数据库，它以一个小型的C语言库的形式存在。它是一个自包含、无需服务器、零配置的数据库引擎。与传统的数据库系统不同，SQLite直接读写普通磁盘文件，不需要单独的数据库服务器。它支持标准的SQL查询语言，并提供了事务支持和ACID属性（原子性、一致性、隔离性和持久性）。</h5>
