【问题描述】：
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'.

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会出现此错误。
有人有想法吗？
提前致谢！

今天和同事有同样的问题。在我的环境中（很久以前设置的 VS Code、.NET Core 和 Omnisharp Extension，但已更新到最新版本）一切正常。在他的 PC（今天设置）上，每个 C# 项目都会出现错误。大多数使用“dotnet new console”创建的简单控制台应用程序也会发生这种情况。因此我猜这是当前版本的 Omnisharp 的一个错误。

感谢您的评论！我尝试了各种方法，我也认为这是当前版本 1.22.1 中的一个错误（根据我在 VS Code 中看到的 Changelog 尚未发布：p）。希望他们很快会发布另一个版本。仍然欢迎任何其他建议。我还在寻找解决方案，如果找到了会发布。如果您的同事找到解决方案，请告诉我。
