Microsoft Android 构建失败 - 无法编译本机程序集文件

Question

我已经在 Visual Studio for mac 2022 中从模板创建了一个 Android 项目（检查了支持的 abi：armebi-v7a）

当我构建项目时，我随机收到一个或多个以下错误：

Xamarin.Android.Common.targets(3,3): Error XA3006: Could not compile native assembly file: environment.arm64-v8a.ll

stderr | /usr/local/share/dotnet/packs/Microsoft.Android.Sdk.Darwin/33.0.26/tools/Darwin/binutils/bin/llc: error: /usr/local/share/dotnet/packs/Microsoft.Android.Sdk.Darwin/33.0.26/tools/Darwin/binutils/bin/llc: environment.arm64-v8a.ll:554:7: error: expected value token
stderr |                 i32 −1, ; apk_fd

(XA3006) (AndroidApp1)

可能是什么问题？它适用于 TargetFramework .net6.0-android

csproj：

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
    <TargetFramework>net7.0-android33.0.0</TargetFramework>
    <SupportedOSPlatformVersion>21</SupportedOSPlatformVersion>
    <OutputType>Exe</OutputType>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <ApplicationId>com.companyname.AndroidApp1</ApplicationId>
    <ApplicationVersion>1</ApplicationVersion>
    <ApplicationDisplayVersion>1.0</ApplicationDisplayVersion>
    <TargetFrameworkVersion>v11.0</TargetFrameworkVersion>
</PropertyGroup>
<PropertyGroup Condition=" '$(Configuration)' == 'Debug' ">
  <AndroidEnableMultiDex>false</AndroidEnableMultiDex>
  <AndroidPackageFormat>apk</AndroidPackageFormat>
</PropertyGroup>

编辑：对于某些语言，xamarin 中存在编码错误。说明和解决方法可以在这里找到：https://github.com/xamarin/xamarin-android/issues/7939

为了解决此问题，我更改了操作系统区域设置作为解决方法，因为 .NET Android 中存在一个错误，该错误应该在之后的版本中得到修复。
