我正在将使用 Entity Framework Core 3.1 和 SQLite 数据库的 Xamarin Forms 5.0 应用程序迁移到 .NET MAUI 6.0 和 Entity Framework Core 6.0。调试构建工作正常，但是当我进行发布构建时，应用程序在启动时崩溃。
在 macOS 上重现它的最简单方法是在 Visual Studio 中使用 .NET MAUI App 模板，编辑项目文件并添加一些配置以确保您可以使用dotnet build (Visual Studio for Mac 的发布版本目前无法运行 https://developercommunity.visualstudio.com/t/Building-in-Release-mode-for-iOS-results/10235007):
<PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Debug|net6.0-ios|AnyCPU'">
<CreatePackage>false</CreatePackage>
<CodesignProvision>Automatic</CodesignProvision>
<CodesignKey>iPhone Developer</CodesignKey>
<RuntimeIdentifier>ios-arm64</RuntimeIdentifier>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Release|net6.0-ios|AnyCPU'">
<CreatePackage>false</CreatePackage>
<CodesignProvision>Automatic</CodesignProvision>
<CodesignKey>iPhone Distribution</CodesignKey>
<RuntimeIdentifier>ios-arm64</RuntimeIdentifier>
</PropertyGroup>
在终端中打开项目文件夹，然后运行
dotnet build MauiEFCore.csproj -c Release -f net6.0-ios -t:Run -p:_DeviceName=<Device UDID>
（请务必指定正确的项目文件和 iPhone 的 UDID）。这是可行的，但是一旦您将 Entity Framework Core 添加到项目中：
<ItemGroup>
<PackageReference Include="Microsoft.EntityFrameworkCore.Sqlite" Version="6.0.11" />
<PackageReference Include="SQLitePCLRaw.bundle_e_sqlite3" Version="2.1.3" />
</ItemGroup>
该应用程序在启动时开始崩溃。有关 Microsoft.Maui.Graphics 的错误似乎无关 - 这只是一个标准的 Maui 模块，对吗？我也无法在控制台应用程序中找到更多信息。

因为调试版本继续工作，我怀疑链接是罪魁祸首；然而，禁用链接 https://i.stack.imgur.com/Ih0Mw.png（相当于添加<MtouchLink>None</MtouchLink>到项目文件）没有效果。我仍然在构建输出中看到这些行：
优化程序集的大小可能会改变应用程序的行为。发布后一定要进行测试。看：https://aka.ms/dotnet-illink https://aka.ms/dotnet-illink
优化装配体的尺寸。这个过程可能需要一段时间。
该链接指向一个有关的页面trimming，这是出乎意料的，因为我没有启用修剪 https://learn.microsoft.com/en-us/dotnet/core/deploying/trimming/trimming-options?pivots=dotnet-6-0#enable-trimming，但显然它是自动的，关闭它会导致另一个错误：
/usr/local/share/dotnet/packs/Microsoft.iOS.Sdk/16.1.229/targets/Xamarin.Shared.Sdk.targets(269,3)：错误：iOS 项目必须使用 PublishTrimmed=true 进行构建。当前值：假。
在我的 Xamarin Forms 项目中我添加了--linkskip System.Core到“iOS 构建选项”中的“其他 mtouch 参数”，如所述here https://learn.microsoft.com/en-us/ef/core/get-started/xamarin#explore-the-code但这并没有帮助 - 详细的构建输出表明它被忽略了：
Task "ParseBundlerArguments"
Skipping unknown argument 'linkskip' with value ''
Done executing task "ParseBundlerArguments".
为了使 Entity Framework Core 在发布模式下工作，我需要做什么？
我已尝试添加链接器设置，如中所述这个答案 https://stackoverflow.com/a/72619246/4751173对于 EF5，甚至在该列表中添加了一些其他程序集（Microsoft.EntityFrameworkCore.Abstractions and SQLitePCLRaw.provider.internal）但无济于事。
FWIW，对于 Android，发布版本工作正常。
