问题描述

刚安装.NET 7.0并创建新的Angular/C# Web应用后，在Mac上遇到以下问题：

使用VSCode构建时抛出异常：Microsoft.NET.Sdk.WorkloadManifestReader.WorkloadManifestCompositionException: Workload定义'wasm-tools': build net7.0 on mac
使用Visual Studio for Mac 17.5打开解决方案时出现microsoft.net.sdk.workloadautoimportpropslocator异常

已尝试移除所有.NET 7.0预览版、执行微软社区修复方案并重启，均未解决问题。

解决方案

针对这类Workload关联异常，可按以下步骤尝试修复：

清理并重装.NET 7.0 Workload
- 打开终端执行缓存清理命令：
```
dotnet workload clean
```
- 安装异常中提到的wasm-tools Workload：
```
dotnet workload install wasm-tools
```
- 验证Workload安装状态：
```
dotnet workload list
```
重置Workload清单缓存
- 删除本地Workload缓存目录：
```
rm -rf ~/.dotnet/workload
rm -rf ~/.dotnet/store
```
- 重新初始化Workload：
```
dotnet workload restore
```
修复Visual Studio for Mac的.NET关联配置
- 打开Visual Studio for Mac，进入Visual Studio > Preferences > .NET
- 确认选中.NET 7.0 SDK，点击Restore按钮重新加载配置
- 关闭并重新打开解决方案

完全卸载重装.NET 7.0

若以上步骤无效，执行完全卸载：

sudo rm -rf /usr/local/share/dotnet/sdk/7.0.100
sudo rm -rf /usr/local/share/dotnet/shared/Microsoft.AspNetCore.App/7.0.0
sudo rm -rf /usr/local/share/dotnet/shared/Microsoft.NETCore.App/7.0.0

重新下载安装.NET 7.0 SDK，完成后再次执行dotnet workload install wasm-tools
