大致了解了Blazor和MAUI之后，尝试创建一个.NET MAUI Blazor应用。
需要注意的是： 虽然都叫MAUI，但.NET MAUI与.NET MAUI Blazor 并不相同，MAUI还是以xaml为主，而MAUI Blazor则是以razor为主。

这个系列还是以MAUI Blazor为主，要创建一个MAUI Blazor应用，需要安装Visual Studio 2022 17.3 或更高版本，并在安装程序上，勾选.NET Multi-platform App UI 开发！最好是升级到最新的.NET 7。

打开Visual Studio 2022，选择创建新项目

在搜索框输入MAUI，选择.NET MAUI Blazor应用，点下一步！

给项目起一个好听的名字，选择项目存在的位置，点下一步！

选择目标框架，这里选择的是.NET 7，点击创建。

等待创建项目及其依赖项还原。完成后的目录结构如下：

.NET MAUI Blazor 需要注意的地方

.NET MAUI Blazor 运行在WebView2上，WebView2是微软推出的新一代用于桌面端混合开发的解决方案。它可以让本地应用程序（WinForm、WPF、WinUI、Win32）、移动应用程序（MAUI）轻松嵌入Web技术。WebView2 控件使用 Microsoft Edge 作为呈现引擎在客户端应用程序及App中显示 Web 内容。使用 WebView2 可以将 Web 代码嵌入到客户端应用程序及App中的不同部分，或在单个 WebView 实例中构建所有本机应用程序。

可以这么看MAUI Blazor， .NET MAUI 包含 BlazorWebView 控件，该控件运行将 Razor 组件呈现到嵌入式 Web View 中。通过结合使用 .NET MAUI 和 Blazor，可以跨移动设备、桌面设备和 Web 重复使用一组 Web UI 组件。

说人话就是，它就是一个Hybrid App（混合应用）！

调试.NET MAUI Blazor

在windows上调试 MAUI Blazor应用，需要Windows 10 1809及更高版本上，并打开开发者模式。
windows 11上，位于设置->隐私和安全性->开发者选项->开发人员模式

点击Windows Machine，运行程序！

如无意外，运行成功！

这时，MAUI Blazor使用的是bootstrap样式以及open-iconic图标。
在wwwroot/index.html中也可以看到

<link rel="stylesheet" href="css/bootstrap/bootstrap.min.css" />

现在已经有个很多基于Blazor的组件库，所以暂时把默认的bootstrap替换成第三方组件库，这里使用的是AntDesignBlazor。

使用AntDesignBlazor 组件库

安装依赖：

PM> NuGet\Install-Package AntDesign.ProLayout -Version 0.13.1

注入AntDesign

在MauiProgram.cs注入AntDesign 服务与设置基本配置，完整的MauiProgram.cs代码

using Microsoft.Extensions.Logging;
using MauiBlazorApp.Data;

namespace MauiBlazorApp;

public static class MauiProgram
{
	public static MauiApp CreateMauiApp()
	{
		var builder = MauiApp.CreateBuilder();
		builder
			.UseMauiApp<App>()
			.ConfigureFonts(fonts =>
			{
				fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
			});

		builder.Services.AddMauiBlazorWebView();

#if DEBUG
		builder.Services.AddBlazorWebViewDeveloperTools();
		builder.Logging.AddDebug();
#endif

		builder.Services.AddSingleton<WeatherForecastService>();
        //注入AntDesign
        builder.Services.AddAntDesign();
		//基本配置
		builder.Services.Configure<ProSettings>(settings =>
		{
            settings.NavTheme = "light";
            settings.Layout = "side";
            settings.ContentWidth = "Fluid";
			settings.FixedHeader = false;
			settings.FixSiderbar = true;
            settings.Title = "DotNet宝藏库";
			settings.PrimaryColor = "daybreak";
			settings.ColorWeak = false;
			settings.SplitMenus= false;
			settings.HeaderRender= true;
			settings.FooterRender= false;
			settings.MenuRender= true;
			settings.MenuHeaderRender= true;
			settings.HeaderHeight = 48;

		});
		return builder.Build();
	}
}

配置项都写上了。参数含义从表达的意思就能看出来，不做注释了！

引入样式

打开wwwroot/index.html。由于我们使用的是AntDesign，所以需要改造下index.html，修改后内容如下：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no, viewport-fit=cover" />
    <title>DotNet宝藏库</title>
    <base href="/" />
    
    <link href="_content/AntDesign/css/ant-design-blazor.css" rel="stylesheet" />
    <link rel="stylesheet" href="_content/AntDesign.ProLayout/css/ant-design-pro-layout-blazor.css" />

加入命名空间

在_Imports.razor添加AntDesign命名空间：

@using System.Net.Http
@using Microsoft.AspNetCore.Components.Forms
@using Microsoft.AspNetCore.Components.Routing
@using Microsoft.AspNetCore.Components.Web
@using Microsoft.AspNetCore.Components.Web.Virtualization
@using Microsoft.JSInterop
@using MauiBlazorApp
@using MauiBlazorApp.Shared
//引入AntDesign
@using AntDesign

设置容器

在Main.razor中加入<AntContainer />

<Router AppAssembly="@typeof(Main).Assembly">
    <Found Context="routeData">
        <RouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)" />
        <FocusOnNavigate RouteData="@routeData" Selector="h1" />
    </Found>
    <NotFound>
        <LayoutView Layout="@typeof(MainLayout)">
            <p role="alert">Sorry, there's nothing at this address.</p>
        </LayoutView>
    </NotFound>
</Router>
<!--设置容器-->
<AntContainer />

修改 MainLayout

修改MainLayout.razor。
把MainLayout.razor中默认布局删除
引入AntDesign.ProLayout
设置布局为AntDesign.ProLayout
构造菜单、页脚的链接、版权
wwwroot目录下新建个文件夹images，把提前准备好的logo放进去

完整代码如下：

@using AntDesign.ProLayout
@inherits LayoutComponentBase

<AntDesign.ProLayout.BasicLayout 
    Logo="@("images/logo.png")"
    MenuData="MenuData">
    <ChildContent>
        @Body
    </ChildContent>
    <FooterRender>
        <FooterView Copyright="MauiBlazorApp" Links="Links"></FooterView>
    </FooterRender>
</AntDesign.ProLayout.BasicLayout>
<SettingDrawer />

@code
{
    private readonly MenuDataItem[] MenuData =
        {
        new MenuDataItem
        {
            Path = "/",
            Name = "Home",
            Key = "Home",
            Icon = "home"
        },
        new MenuDataItem
        {
            Path = "/Counter",
            Name = "Counter",
            Key = "Counter",
            Icon = "plus"
        },
        new MenuDataItem
        {
            Path = "/FetchData",
            Name = "FetchData",
            Key = "FetchData",
            Icon = "cloud"
        }
    };
    private readonly LinkItem[] Links =
    {
        new LinkItem
        {
            Key = "DotNet宝藏库",
            Title = "基于Ant Design Blazor",
            Href = "https://antblazor.com",
            BlankTarget = true
        }
    };
}

这时可以把项目中无用的内容删除掉了，如Shared/NavMenu.razor、wwwroot/css文件。
由于删除掉了css文件夹，页面元素肯定没有样式了。那么就简单的改造下默认的几个页面！

改造默认页面

index.razor

打开Pages/Index.razor，将演示组件SurveyPrompt 删掉。顺便把Shared/SurveyPrompt.razor也删除掉。将<h1>Hello, world!</h1>
替换为Ant Design组件。

@page "/"

<Title Level="1">Hello,DotNet宝藏库</Title>

<br />
<Text Type="success">欢迎关注我的公众号！</Text>

Counter.razor

打开 Pages/Counter.razor,将代码改为如下：

@page "/counter"

<Title Level="2">HCounter</Title>
<Divider />
<p role="status">Current count: @currentCount</p>

<Button @onclick="IncrementCount" Type="primary">AntDesign 按钮</Button>
@code {
    private int currentCount = 0;

    private void IncrementCount()
    {
        currentCount++;
    }
}

FetchData.razor

打开Pages/FetchData.razor，将数据表格替换为Ant Design，删除页面所有代码，替换为Ant Design的示例！

@page "/fetchdata"
@using System.ComponentModel
@using AntDesign.TableModels
@using System.Text.Json

@using MauiBlazorApp.Data
@inject WeatherForecastService ForecastService

<Table @ref="table"
       TItem="WeatherForecast"
       DataSource="@forecasts"
       Total="_total"
       @bind-PageIndex="_pageIndex"
       @bind-PageSize="_pageSize"
       @bind-SelectedRows="selectedRows"
       OnChange="OnChange">
    <Selection Key="@(context.Id.ToString())" />
    <PropertyColumn Property="c=>c.Id" Sortable />
    <PropertyColumn Property="c=>c.Date" Format="yyyy-MM-dd" Sortable />
    <PropertyColumn Property="c=>c.TemperatureC" Sortable />
    <PropertyColumn Title="Temp. (F)" Property="c=>c.TemperatureF" />
    <PropertyColumn Title="Hot" Property="c=>c.Hot">
        <Switch @bind-Value="@context.Hot"></Switch>
    </PropertyColumn>
    <PropertyColumn Property="c=>c.Summary" Sortable />
    <ActionColumn>
        <Space>
            <SpaceItem><Button Danger OnClick="()=>Delete(context.Id)">Delete</Button></SpaceItem>
        </Space>
    </ActionColumn>
</Table>
<br />
<p>PageIndex: @_pageIndex | PageSize: @_pageSize | Total: @_total</p>

<br />
<h5>selections:</h5>
@if (selectedRows != null && selectedRows.Any())
{
    <Button Danger Size="small" OnClick="@(e => { selectedRows = null; })">Clear</Button>

    @foreach (var selected in selectedRows)
    {
        <Tag @key="selected.Id" Closable OnClose="e=>RemoveSelection(selected.Id)">@selected.Id - @selected.Summary</Tag>
    }
}

<Button Type="@ButtonType.Primary" OnClick="()=> { _pageIndex--; }">Previous page</Button>
<Button Type="@ButtonType.Primary" OnClick="()=> { _pageIndex++; }">Next Page</Button>

@code {
    private WeatherForecast[] forecasts;
    IEnumerable<WeatherForecast> selectedRows;
    ITable table;
    int _pageIndex = 1;
    int _pageSize = 10;
    int _total = 0;

    protected override async Task OnInitializedAsync()
    {
        forecasts = await GetForecastAsync(1, 50);
        _total = 50;
    }
    public class WeatherForecast
    {
        public int Id { get; set; }

        [DisplayName("Date")]
        public DateTime? Date { get; set; }

        [DisplayName("Temp. (C)")]
        public int TemperatureC { get; set; }

        [DisplayName("Summary")]
        public string Summary { get; set; }

        public int TemperatureF => 32 + (int)(TemperatureC / 0.5556);

        public bool Hot { get; set; }
    }
    private static readonly string[] Summaries = new[]
    {
        "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
    };
    public void OnChange(QueryModel<WeatherForecast> queryModel)
    {
        Console.WriteLine(JsonSerializer.Serialize(queryModel));
    }
    public Task<WeatherForecast[]> GetForecastAsync(int pageIndex, int pageSize)
    {
        var rng = new Random();
