带有 asp.net core 1.1 应用程序的omnisharp

Question

我正在尝试在 vi (neovim) 中为 asp.net core 1.1 应用程序完成代码

这里是omnisharp server + vim 插件： https://github.com/OmniSharp/Omnisharp-vim

在我的 .vimrc 中我添加了这个：

Plug 'OmniSharp/omnisharp-vim'
let g:OmniSharp_server_type = 'roslyn'

（我认为 .net 核心需要 roslyn？）

我还克隆并编译了omnisharp roslyn服务器，没有错误。
但是当我启动 OmniSharp 时，我得到了这个错误：

/.local/share/nvim/plugged/omnisharp-vim/omnisharp-roslyn> ./artifacts/scripts/OmniSharp

为什么我还需要 Mono？ dotnet core 还不够吗？
dotnet core 是否仅适用于 Roslyn？
vscode 用什么来完成 c# 补全？罗斯林？
这里可能是什么问题？

更新：

我从 roslyn 文件夹 (~/.local/share/nvim/plugged/omnisharp-vim/omnisharp-roslyn) 进行了发布，如下所示：'dotnet publish -c Release -f netcoreapp1.1'

然后我将文件从发布文件夹 (~/.local/share/nvim/plugged/omnisharp-vim/omnisharp-roslyn/artifacts/publish/OmniSharp/default/netcoreapp1.1) 复制到脚本文件夹 (~ /.local/share/nvim/plugged/omnisharp-vim/omnisharp-roslyn/artifacts/scripts）。

不确定这是否是正确的解决方案，但它似乎有效。

更新 2：

最后我只是从这里下载了一个版本：https://github.com/OmniSharp/omnisharp-roslyn/releases

然后我将 omnisharp-vim/omnisharp-roslyn/artifacts/scripts/OmniSharp 更改为如下内容：

#!/bin/bash
"/<path>/omnisharp-vim/omnisharp-osx-x64-netcoreapp1.1/Omnisharp" "$@"

现在可以了

Answer 1

通常System.DllNotFoundException: System.Native异常发生是因为你刚刚复制了编译文件夹，这是错误的，你必须发布应用程序然后使用该文件夹中的文件，将有应用程序需要运行的所有库。
