Question

我正在尝试在Visual Studio Code C#中启动一个非常小的初始项目。我的操作系统是Ubuntu-18.04

我有节点版本v12.15.0

npm版本6.13.4

可视代码版本1.42.0

我已经安装了sudo apt-get install dotnet-sdk-3.1，并且安装成功。安装过程来自offical instructions for Ubuntu-18.04

1）wget -q https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb

2）如下安装：

sudo add-apt-repository universe
sudo apt-get update
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-3.1

这是下面dotnet --info的结果：

emanuele@pc:~$ dotnet --info
.NET Core SDK (reflecting any global.json):
 Version:   3.1.102
 Commit:    573d158fea

Runtime Environment:
 OS Name:     ubuntu
 OS Version:  18.04
 OS Platform: Linux
 RID:         ubuntu.18.04-x64
 Base Path:   /usr/share/dotnet/sdk/3.1.102/

Host (useful for support):
  Version: 3.1.2
  Commit:  916b5cba26

.NET Core SDKs installed:
  3.1.102 [/usr/share/dotnet/sdk]

.NET Core runtimes installed:
  Microsoft.AspNetCore.App 3.1.2 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 3.1.2 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

To install additional .NET Core runtimes or SDKs:
  https://aka.ms/dotnet-download

安装成功作为最终结果。

我继续使用Visual Studio，并输入以下内容创建了一个新项目：

1）sudo npm install -g yo bower grunt-cli gulp generator-aspnet

2）yo aspnet并正确收到了如下所示的欢迎信息，并选择了 Web应用程序，因为我希望将来使用google-drive API方法作为可应用程序：

welcome

说明如下所示，但当我dotnet run或sudo dotnet run时，我收到以下消息：

run

如果有人要复制/粘贴，Iam也会报告：

[fail]: OmniSharp.MSBuild.ProjectManager

我用来帮助我解决问题的帖子是：

1）fail-omnisharp-msbuild-projectmanager

2）this one，因为我的操作系统也是Ubuntu-18.04，但是在我看来这不是可行的解决方案，因为它需要手动安装文件。我不确定这是正确的程序。

3）This is useful但是用户使用Windows，所以我不确定这是否也是可修复的解决方案

如果有人遇到与我相同的问题，感谢您提供解决此问题的指导。
