OmniSharp无法在Visual Studio Code中启动

我在Kubuntu 15.04下的VSCode(v.0.10.3)中的C#上打开现有MSBuild项目(实际上来自VS 2012)的文件夹.启动后OmniSharp抛出错误:

[INFO] Starting OmniSharp at '/home/tezaurismosis/Development/NET/ConsoleApp/ConsoleApp.sln'...

我已经安装了最新版本的Mono(4.2.1)以及所有带有Mono程序集的子包,安装dnvm并运行dnvm upgrade -r mono,运行dnu restore,但OmniSharp一次又一次失败,IntelliSence在VSCode中无法工作.

我该如何解决？

PS它不是ASP.NET,只是控制台C#项目.

您的版本可能已过期.在vs代码中卸载并重新安装C#扩展.

按F1,键入ext show installed,按Enter.单击x以将其删除.

重启vscode.

按F1,键入ext install,按Enter.单击下载图标进行安装.

重启vscode.

Ominsharp现在将运行.
