我一直在使用NET MAUI完成的工具。现在我想自动化Windows UI，但我不知道如何做到这一点。我尝试下载FlaUI NuGet，但无法让它工作，因为它需要项目是Net7.0-windows。所以我创建了新的项目与Net7.0-windows的参考，但我在Net Maui的参考得到损坏。

MauiApp1.csproj（项目）：

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <TargetFrameworks>net7.0-android;net7.0-ios;net7.0-maccatalyst</TargetFrameworks>
        <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net7.0-windows10.0.19041.0</TargetFrameworks>
        <!-- Uncomment to also build the tizen app. You will need to install tizen by following this: https://github.com/Samsung/Tizen.NET -->
        <!-- <TargetFrameworks>$(TargetFrameworks);net7.0-tizen</TargetFrameworks> -->
        <OutputType>Exe</OutputType>
        <RootNamespace>MauiApp1</RootNamespace>
        <UseMaui>true</UseMaui>
        <SingleProject>true</SingleProject>
        <ImplicitUsings>enable</ImplicitUsings>

        <!-- Display name -->

        <SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'tizen'">6.5</SupportedOSPlatformVersion>
    </PropertyGroup>

    <ItemGroup>
        <!-- App Icon -->
        <MauiIcon Include="Resources\AppIcon\appicon.svg" ForegroundFile="Resources\AppIcon\appiconfg.svg" Color="#512BD4" />

        <!-- Splash Screen -->
        <MauiSplashScreen Include="Resources\Splash\splash.svg" Color="#512BD4" BaseSize="128,128" />

        <!-- Images -->
        <MauiImage Include="Resources\Images\*" />
        <MauiImage Update="Resources\Images\dotnet_bot.svg" BaseSize="168,208" />

        <!-- Custom Fonts -->
        <MauiFont Include="Resources\Fonts\*" />

        <!-- Raw Assets (also remove the "Resources\Raw" prefix) -->
        <MauiAsset Include="Resources\Raw\**" LogicalName="%(RecursiveDir)%(Filename)%(Extension)" />
    </ItemGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="7.0.0" />
    </ItemGroup>

</Project>

项目ClassLibrary1.csproj（项目）：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net7.0-windows</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>

    <PackageReference Include="FlaUI.Core" Version="4.0.0" />
    <PackageReference Include="FlaUI.UIA3" Version="4.0.0" />

我得到以下错误：

我的问题是如何在NET MAUI中引用MauiApp1.csproj中的ClassLibrary1.csproj？有什么方法可以让这个设置工作吗？

如果你的ClassLibrary1项目支持所有平台，那么你也应该把这几行添加到你的ClassLibrary1.cspoj文件中。

<TargetFrameworks>net7.0-android;net7.0-ios;net7.0-maccatalyst</TargetFrameworks>
<TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net7.0-windows10.0.19041.0</TargetFrameworks>

如果你的ClassLibrary1项目只支持windows，那么你可以做两件事;
1.如果你的MAUI项目只在windows上运行，那么在你的MauiApp1.csproj文件中你应该删除这些行;

<TargetFrameworks>net7.0-android;net7.0-ios;net7.0-maccatalyst</TargetFrameworks>

<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">11.0</SupportedOSPlatformVersion>
<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'maccatalyst'">13.1</SupportedOSPlatformVersion>
<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">21.0</SupportedOSPlatformVersion>
<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'tizen'">6.5</SupportedOSPlatformVersion>

1.如果你的MAUI应用程序要同时支持其他平台，你应该单独添加你的平台特定库。我正在为我的多平台MAUI应用程序使用这个。
Solution Explorer > Your MAUI Project > Dependencies > Right Click Your Platform > Add reference
然后打开你的MauiApp1.csproj文件，找到你的引用，给你的引用加上一个条件，你的引用应该是这样的结尾;

<ItemGroup Condition="$(TargetFramework.Contains('-windows')) != false ">
  <ProjectReference Include="..\MauiLib1\MauiLib1.csproj" />
</ItemGroup>

- 示例**

我已经做了一个例子。我创建了一个名为MauiApp1的MAUI项目和一个名为MauiLib1的类库。MauiLib1只支持Windows平台，MauiApp1支持所有平台。我已经将MauiLib1添加到MauiApp1中，但仅适用于Windows平台。所需的.csproj文件和特定于平台的代码可以在下面看到。

MauiApp1.csproj

<PropertyGroup>
     <TargetFrameworks>net7.0-android;net7.0-ios;net7.0-maccatalyst</TargetFrameworks>
     <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net7.0-windows10.0.19041.0</TargetFrameworks>

     <SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">11.0</SupportedOSPlatformVersion>
     <SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'maccatalyst'">13.1</SupportedOSPlatformVersion>
     <SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">21.0</SupportedOSPlatformVersion>
     <SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">10.0.17763.0</SupportedOSPlatformVersion>
     <TargetPlatformMinVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">10.0.17763.0</TargetPlatformMinVersion>
     <SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'tizen'">6.5</SupportedOSPlatformVersion>
 </PropertyGroup>

 <ItemGroup Condition="$(TargetFramework.Contains('-windows')) != false ">
   <ProjectReference Include="..\MauiLib1\MauiLib1.csproj" />
 </ItemGroup>

MauiLib1.csproj

<PropertyGroup>
     <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net7.0-windows10.0.19041.0</TargetFrameworks>

     <SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">10.0.17763.0</SupportedOSPlatformVersion>
     <TargetPlatformMinVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">10.0.17763.0</TargetPlatformMinVersion>
 </PropertyGroup>

MauiLib1项目中的一个简单类。因此我们可以进行测试。

public static class MauiLib1TestClass
 {
     public static string testString = "ehehehe";
 }

稍微更改了MauiApp1项目的默认MainPage.xaml.cs代码。在这里您可以看到Windows特定的代码。如果没有这些条件，您的应用程序将崩溃。因为将不会有该平台的引用。

#if WINDOWS
 using MauiLib1;
 #endif

 public partial class MainPage : ContentPage
 {
     int count = 0;

     public MainPage()
     {
         InitializeComponent();
     }

     private void OnCounterClicked(object sender, EventArgs e)
     {
         count++;

         if (count == 1)
             CounterBtn.Text = $"Clicked {count} time";
 #if WINDOWS
         else if (count == 3)
             CounterBtn.Text = MauiLib1TestClass.testString;
 #endif
         else
             CounterBtn.Text = $"Clicked {count} times";

         SemanticScreenReader.Announce(CounterBtn.Text);
     }
 }
