c# - VS Code Omnisharp.MsBuild.Projectmanager 无法加载程序集 System.Numerics.Vectors 4.1.3.0

Question

我在打开新创建的 blazorwasm 项目时遇到问题。 Omnisharp 将无法正确启动。这是输出:

[warn]: OmniSharp.MSBuild.ProjectManager Failed to load project file 'c:\VS.NET2010\CoreApp\Server\CoreApp.Server.csproj'.

WRSCH: registratie van assembly-bindingen is uitgeschakeld.
Als u assembly-bindingsfouten wilt registreren, stelt u de registerwaarde [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) in op 1.
Opmerking: er is een prestatiestraf gekoppeld aan de registratie van assembly-bindingsfouten.
Als u deze functie wilt uitschakelen, verwijdert u de registerwaarde [HKLM\Software\Microsoft\Fusion!EnableLog].

这是 csproj 文件:

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.Server" Version="3.2.0" />
  </ItemGroup>
  <ItemGroup>
    <ProjectReference Include="..\Client\CoreApp.Client.csproj" />
    <ProjectReference Include="..\Shared\CoreApp.Shared.csproj" />
  </ItemGroup>
</Project>

我不知道为什么会出现此错误。因此，我无法在此项目中使用 IntelliSense。 我的一个同事没有这个问题。他可以使用以下命令创建一个类似的项目: dotnet new blazorwasm -o CoreApp --hosted

在他的 PC 上，项目可以正常打开，没有任何 OmniSharp 警告。

我不知道为什么我的电脑上会出现此错误。

有人有想法吗？

提前致谢!

问题在于，C# for Visual Studio Code(由 OmniSharp 提供支持)VS Code 扩展中包含的 MSBuild 无法正确找到系统上特定的 4.1.3.0 版本的 System.Numerics.Vectors。

最好的解决方案是添加正确版本的 DLL

C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Numerics.Vectors\v4.0_4.1.3.0__b03f5f7f11d50a3a

另一个解决方案是安装 .NET Core SDK 3.1.301，其中包含该版本的 System.Numerics.Vectors 程序集，然后复制

C:\Program Files\dotnet\sdk\3.1.301\Sdks\Microsoft.NET.Sdk.WindowsDesktop\tools\net472\System.Numerics.Vectors.dll

至

%USERPROFILE%\.vscode\extensions\ms-dotnettools.csharp-1.22.1\.omnisharp\1.35.3\.msbuild\Current\Bin

此问题可能会在更高版本的 C# for Visual Studio Code(由 OmniSharp 提供支持)VS Code 扩展中得到解决
