说明：
.net core版本为:2.2
adminlte版本为:2.4.18
bootstrap版本为:3.4.1
font-awesome版本为:4.7.0
1、使用vs 2017新建项目：adminltedemo，完成后添加区域admin
在areas/admin/views文件夹添加文件并分别添加如下代码，主要为引用和页面布局使用，这两个文件直接从创建模板里面创建就可以，不用修改名称：
_viewimports.cshtml
@addtaghelper *, microsoft.aspnetcore.mvc.taghelpers
_viewstart.cshtml
@{
layout = "_layout";
}
2、在startup类中添加对区域路由的代码，使用home管理作为默认路由地址如下:
app.usemvc(routes =>
{
routes.maproute(
name: "areas",
template: "{area:exists}/{controller=homemanagement}/{action=index}/{id?}");
routes.maproute(
name: "default",
template: "{controller=home}/{action=index}/{id?}");
});
3、在areas/admin/contorllers文件夹中添加两个控制器
home管理控制器homemanagementcontroller，记得添加区域信息，不然路由找不到内容，代码如下:
[area("admin")]
public class homemanagementcontroller : controller
{
public iactionresult index()
{
return view();
}
}
学生管理控制器studentmanagementcontroller，记得添加区域信息，不然路由找不到内容，代码如下:
[area("admin")]
public class studentmanagementcontroller : controller
{
public iactionresult index()
{
return view();
}
}
4、对homemanagementcontroller的action添加对应的视图文件，代码如下：
@{
viewdata["title"] = "index";
}
<section class="content-header">
<h1>home management index</h1>
</section>
对studentmanagementcontroller的action添加对应的视图文件，代码如下：
@{
viewdata["title"] = "index";
}
<section class="content-header">
<h1>student management index</h1>
</section>
两个视图里面都添加了一个h1标题，已区分不同的内容
5、使用libman添加对adminlte、bootstrap和font-awesome的引用
方法：wwwroot\lib 右键:添加->客户端库
注意：bootstrap 3.*版本为twitter-bootstrap
由于项目自带的bootstrap版本为4.*，所以需要添加对bootstrap 3.*版本引用
在areas/admin/views添加shared文件夹，并添加_layout.cshtml文件，代码如下：
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<meta http-equiv="x-ua-compatible" content="ie=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1,maximum-scale=1,user-scalable=no" />
<title>@viewbag.title</title>
<link rel="stylesheet" href="~/lib/twitter-bootstrap/css/bootstrap.css" />
<link rel="stylesheet" href="~/lib/font-awesome/css/font-awesome.css" />
<link rel="stylesheet" href="~/lib/admin-lte/css/adminlte.css" />
<link rel="stylesheet" href="~/lib/admin-lte/css/skins/_all-skins.css" />
<link rel="stylesheet" href="~/lib/icheck/skins/flat/blue.css" />
</head>
@{
var controller = (string)viewcontext.routedata.values["controller"];
}

_layout.cshtml文件中adminlte主要分为如下及部分：
- main-header
- main-sidebar
- content-wrapper
- main-footer
其中，1、2、4在项目充基本是固定的，3是需要根据权限、人员进行动态分配的和调整的
运行效果图
需要解决的问题：
- 动态菜单分配问题
希望adminlte能出一版bootstr 4.*的后台管理框架
