OmniSharp.MSBuild.ProjectManager 无法在 Linux 上加载项目

Question

我正在我的 Manjaro Linux 笔记本上学习 C#。我尝试安装 ms-vscode.csharp 扩展，但在打开任何 .NET Core 项目时，我收到以下错误消息：

Some Projects have trouble loading. Please review the output for more information.

我尝试将 VS Code 设置中的 "omnisharp.path" 选项设置为 "latest" 但它没有改变任何东西。

我使用的是 1.21.8 版的扩展和 1.40.2 版的 VS Code。

有解决问题的想法吗？

Answer 1

我通过添加包含以下内容的 omnisharp.json 文件解决了这个问题：

{
    "MSBuild": {
        "UseLegacySdkResolver": true
    }
}

Answer 2

您收到此错误的部分原因是您的项目中缺少 .vscode。 Omnisharp 寻找.Net SDK 版本的路径是错误的，这是因为Omnisharp 在Visual Studio 保存其资源的路径中寻找所需的SDK。要解决此问题，请更新您的 visual studio，使其具有您正在使用的最新 SDK 版本。这应该可以解决错误，您在 Visual Studio 代码上运行的项目将有 the.VSCode 文件夹。

要更新 Visual Studio，请打开顶部菜单中的 Visual Studio 和 select 帮助，查找“检查更新”，然后进行更新。

如果您当时已经完成所有这些操作，简单的 Vs Code 重启可能就是答案。

Answer 3

这似乎已经为我完成了代码 -> 首选项 -> 设置 -> 单击此

;/ 希望我至少有 10 个声望 post 这里的图片但是它是右上角的第一个图标看起来像一张小纸片。

然后..

将意大利面复制到 settings.json

{
  "explorer.compactFolders": false,
  "update.mode": "none",
  "workbench.iconTheme": "vscode-icons",
  "editor.formatOnSave": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "omnisharp.path": "latest",
  "omnisharp.monoPath": "auto",
  "csharp.semanticHighlighting.enabled": true,
  "editor.formatOnType": true,
  "[csharp]": {
    "editor.defaultFormatter": "ms-dotnettools.csharp"
  },
  "[xml]": {
    "editor.defaultFormatter": "DotJoshJohnson.xml"
  },

  "settingsSync.ignoredExtensions": [],
  "window.zoomLevel": 0
}

那个^

"[csharp]": {
    "editor.defaultFormatter": "ms-dotnettools.csharp"
  },
  "[xml]": {
    "editor.defaultFormatter": "DotJoshJohnson.xml"
  },

但我认为这就是我的诀窍 ^ 特别是 [csharp]

Answer 4

通过查看启动日志，我看到一条消息说我需要 .NET Developer Pack 4.7.1。

从 https://docs.microsoft.com/de-de/dotnet/framework/install/guide-for-developers 下载并安装 .NET Framework 4.7.1（开发包）解决了我的问题。
