OmniSharp.MSBuild.ProjectManager 尝试更新未加载的项目：csharp

如何解决OmniSharp.MSBuild.ProjectManager 尝试更新未加载的项目：csharp

好吧，我知道已经有大约 100 个答案和方法可以解决这个问题，但是我已经尝试了所有方法，但都行不通。

所以这是出现在控制台上的错误

[fail]: OmniSharp.MSBuild.ProjectManager
        Attempted to update project that is not loaded: c:\Users\Diego\Documents\Programación\Unity\Firs tutorial\Assembly-CSharp.csproj

这里是csproj文件

我已经下载了 dot net SDK 和框架的十倍，但它根本不起作用。这些问题有大约 100 万个可能的来源，我只需要一些帮助。我已经尝试解决这个问题好几天了，但我不能，如果有人能帮助我，我将不胜感激。

解决方法

在 VS Code 菜单中，进入 File / Preferences / Settings。
在“搜索设置”窗口中，输入 omnisharp.path
点击“在 settings.json 中编辑”链接。
添加（或编辑）如下："omnisharp.path": "latest"

另外，另一个问题：您使用的是什么操作系统？您发布的 proj 文件是旧格式，而不是 SDK 格式，我怀疑它是否在 Windows 之外兼容。转换为 SDK 相当容易：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <LangVersion>latest</LangVersion>
    <TargetFramework>net471</TargetFramework>
    <WarningLevel>4</WarningLevel>
    <NoWarn>0169</NoWarn>
    <NoConfig>true</NoConfig>
    <NoStdLib>true</NoStdLib>
    <AddAdditionalExplicitAssemblyReferences>false</AddAdditionalExplicitAssemblyReferences>
    <ImplicitlyExpandNETStandardFacades>false</ImplicitlyExpandNETStandardFacades>
    <ImplicitlyExpandDesignTimeFacades>false</ImplicitlyExpandDesignTimeFacades>
  </PropertyGroup>
</Project>

或者您可以使用 dotnet new 或 Visual Studio 使用新的项目模板从头开始创建（可能还有适用于 VSCode 的插件）
