Question

我有一个UWP应用程序，已使用Uno平台移植到iOS和Android。我可以在Windows上构建并运行iOS项目，但是当我尝试在Mac上运行它时，出现以下错误：

错误：System.TypeLoadException：无法加载字段'Microsoft.CodeAnalysis.SQLite.Interop.SqlConnection：_handle'（0）的类型，原因是：无法加载文件或程序集'SQLitePCLRaw.core，Version = 1.0.0.0 ，Culture = neutral，PublicKeyToken = 1488e028ca7ab535'或其依赖项之一。

即使我添加对该程序包的引用，错误仍然存在，并且我无法运行该项目。完整的堆栈跟踪如下：

/.../MyProject/packages/Uno.SourceGenerationTasks.1.28.0/build/Xamarin.iOS10/Uno.SourceGenerationTasks.targets(4,4): Error: System.TypeLoadException: Could not load type of field 'Microsoft.CodeAnalysis.SQLite.Interop.SqlConnection:_handle' (0) due to: Could not load file or assembly 'SQLitePCLRaw.core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1488e028ca7ab535' or one of its dependencies.

我正在使用Uno.Platform的最新发行版（未预发行）：

  <package id="Uno.CodeGen" version="1.29.0" targetFramework="xamarinios10" />
  <package id="Uno.Core" version="1.25.0" targetFramework="xamarinios10" />
  <package id="Uno.Core.Build" version="1.25.0" targetFramework="xamarinios10" />
  <package id="Uno.Equality" version="1.29.0" targetFramework="xamarinios10" />
  <package id="Uno.Immutables" version="1.29.0" targetFramework="xamarinios10" />
  <package id="Uno.Injectable" version="1.29.0" targetFramework="xamarinios10" />
  <package id="Uno.SourceGenerationTasks" version="1.28.0" targetFramework="xamarinios10" />
  <package id="Uno.UI" version="1.42.0" targetFramework="xamarinios10" />

是否可以运行在Mac上使用Uno平台开发的iOS应用？

Answer 1

正如安德列斯（Andres）所述，此问题已在最新开发人员中修复。如果需要，可以在我们的Gitter频道上获得更多帮助：https://gitter.im/uno-platform/Lobby#

Answer 2

我试图将Uno.UI软件包更新为最新的预发行版-它没有帮助。我不仅需要更新Uno.UI软件包，还必须手动更新所有未使用Uno.UI提取的相关软件包：

  <package id="Uno.CodeGen" version="1.30.0-dev.107" targetFramework="xamarinios10" />
  <package id="Uno.Core" version="1.26.0-dev.61" targetFramework="xamarinios10" />
  <package id="Uno.Core.Build" version="1.26.0-dev.61" targetFramework="xamarinios10" />
  <package id="Uno.Equality" version="1.30.0-dev.107" targetFramework="xamarinios10" />
  <package id="Uno.Immutables" version="1.30.0-dev.107" targetFramework="xamarinios10" />
  <package id="Uno.Injectable" version="1.30.0-dev.107" targetFramework="xamarinios10" />
  <package id="Uno.Roslyn" version="1.2.0-dev.18" targetFramework="xamarinios10" />
  <package id="Uno.SourceGenerationTasks" version="1.29.0-dev.226" targetFramework="xamarinios10" />
  <package id="Uno.UI" version="1.43.0-dev.614" targetFramework="xamarinios10" />

此软件包列表正常工作。

无法在Mac上为iOS运行Uno项目-无法加载SQLitePCLRaw.core
