.NET 8 MAUI解决方案在VS for Mac 17.6.7编译失败，命令行正常，如何解决？

我有一个从.NET 7升级至.NET 8的MAUI解决方案，在Visual Studio for Mac 17.6.7中编译失败，但通过dotnet命令行执行build操作可成功编译。

Visual Studio for Mac报错信息 #

/usr/local/share/dotnet/sdk/7.0.403/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.TargetFrameworkInference.targets(5,5): Error NETSDK1045: The current .NET SDK does not support targeting .NET 8.0. Either target .NET 7.0 or lower, or use a version of the .NET SDK that supports .NET 8.0. Download the .NET SDK from https://aka.ms/dotnet/download (NETSDK1045) (Doma.SharedInterfaces)

dotnet命令行编译结果 #

进入解决方案目录执行dotnet build后编译成功，输出如下：

可以让该解决方案在Visual Studio for Mac中正常编译，具体操作如下：

1. 升级Visual Studio for Mac版本 #

Visual Studio for Mac 17.6.7默认绑定.NET 7 SDK，不支持.NET 8项目编译。需将IDE升级至17.7及以上版本，这类版本已原生适配.NET 8 SDK。

2. 手动指定IDE使用.NET 8 SDK（无需升级IDE时） #

• 打开Visual Studio for Mac，点击顶部菜单栏Visual Studio -> Settings
• 在设置窗口选择Projects -> .NET Runtimes
• 在已安装的SDK列表中找到.NET 8.0版本，设为默认SDK
• 重启IDE后重新加载解决方案并编译

3. 检查项目与全局SDK配置 #

• 逐个打开项目的.csproj文件，确认<TargetFramework>节点值为net8.0（MAUI项目需确保多目标框架如net8.0-android、net8.0-ios等配置正确）
• 若解决方案根目录存在global.json文件，检查其sdk.version是否指定了正确的.NET 8版本，示例：

  {
    "sdk": {
      "version": "8.0.100"
    }
  }
  

4. 清理恢复后重新编译 #

• 在Visual Studio for Mac中点击Build -> Clean All
• 接着点击Build -> Restore NuGet Packages
• 最后执行编译操作
