Language server suddenly changed the language type from go to c#

@saibing thanks for logging this issue I've also seen this happen while working in reason files tbh I had no idea a csproj file was for c# so I didnt realise it wasn't reason related. I'm not sure if some legacy code from when oni-plugin-csharp might be being triggered.

To clarify do you have the oni-plugin-csharp plugin installed?

There is no oni-plugin-csharp in my oni extensions directory:

@Akin909 My config.tsx content as follow:

import * as React from "/data/saibing/git/ts/oni/node_modules/react"
import * as Oni from "/data/saibing/git/ts/oni/node_modules/oni-api"

export const activate = (oni: Oni.Plugin.Api) => {
    console.log("config activated")

    // Input
    //
    // Add input bindings here:
    //
    oni.input.bind("<c-enter>", () => console.log("Control+Enter was pressed"))
    oni.input.bind("<s-c-r>", "oni.editor.findAllReferences")
    oni.input.bind("<s-insert>", "editor.clipboard.paste")
    oni.input.unbind("<c-g>") // make c-g work as expected in vim
    oni.input.bind("<s-c-g>", () => oni.commands.executeCommand("sneak.show"))
    //oni.input.bind("<c-]", "oni.editor.gotoDefinition")

    //
    // Or remove the default bindings here by uncommenting the below line:
    //
    // oni.input.unbind("<c-p>")

}

export const deactivate = (oni: Oni.Plugin.Api) => {

@Akin909 If I create .git directory in $GOROOT/src, Oni will work well.

I believe this is just a wrong error message:

https://github.com/onivim/oni/blob/3f2fe46de64586c62b11b9d1f90fb37e07b86a5b/browser/src/Utility.ts#L128-L134

The "csproj" is hard coded, but this appears to be a general utility.

Thanks for catching that @tmandry, think its probably a very old remnant of having the csharp oni plugin though it predates me, but at least that explains things and we can look at fixing that 👍
