Omnisharp-vscode: 1.6.0: Extension host terminated unexpectedly. Please reload the window to recover.

Created on 22 Dec 2016  路  15Comments  路  Source: OmniSharp/omnisharp-vscode

Environment data

dotnet --info output:
.NET Command Line Tools (1.0.0-preview2-003121)

Product Information:
Version: 1.0.0-preview2-003121
Commit SHA-1 hash: 1e9d529bc5

Runtime Environment:
OS Name: Mac OS X
OS Version: 10.12
OS Platform: Darwin
RID: osx.10.12-x64

VS Code version:
1.8.1
C# Extension version:
1.6.0

Steps to reproduce

Open a C# file. Omnisharp is starting up and when it's almost finished: "Extension host terminated unexpectedly. Please reload the window to recover."

Expected behavior

No crash and a working C# environment. I don't see an exception in the Omnisharp log. It ends with:

[INFORMATION:OmniSharp#MSBuild] MSBUILD_EXE_PATH environment variable set to /Users/tverboon/.vscode/extensions/ms-vscode.csharp-1.6.0/bin/omnisharp/msbuild/MSBuild.dll
[INFORMATION:OmniSharp#MSBuild] MSBuildExtensionsPath environment variable set to /Users/tverboon/.vscode/extensions/ms-vscode.csharp-1.6.0/bin/omnisharp/msbuild
[INFORMATION:OmniSharp#MSBuild] MSBuildSDKsPath environment variable set to /Users/tverboon/.vscode/extensions/ms-vscode.csharp-1.6.0/bin/omnisharp/msbuild/Sdks
[INFORMATION:OmniSharp#MSBuild] No solution files found in '/Users/tverboon/Desktop/Code/Midmid'
[INFORMATION:OmniSharp.Script.ScriptProjectSystem] Detecting CSX files in '/Users/tverboon/Desktop/Code/Midmid'.
[INFORMATION:OmniSharp.Script.ScriptProjectSystem] Could not find any CSX files
[INFORMATION:OmniSharp.Startup] Configuration finished.

Actual behavior

"Extension host terminated unexpectedly. Please reload the window to recover." And C# is not working.

Extra info:
I did some extra testing as I had to reinstall the previous version. For me the extension causes a crash in 1.6-beta7. 1.6-beta6 and before are working.

Appears to be after project selection that it crashes.

Same, in win 7 environment.

This happens every time I select a *.cs file

That sounds pretty terrible, and I haven't seen it before. One idea I have is that a previous version of the extension did not uninstall cleanly. Try this:

  1. Close Visual Studio Code.
  2. Delete all versions of the C# extension from disk.

    • Windows: Go to %UserProfile%\.vscode\extensions\ and delete any ms-vscode.csharp.* extensions.

    • OSX/Linux: Go to ~/.vscode/extensions/ and delete any ms-vscode.csharp.* extensions.

  3. Launch Visual Studio Code with your project and open a C# file.
  4. At this point, Visual Studio Code should recommend installing the latest C# extension.
  5. Go ahead and install the latest C# extension.

After re-installing, if the issue still occurs select "Help -> Toggle Developer Tools" and choose the "Console" tab. Let me know what you see in that tab.

Hi, I reinstalled the extensions, opened a C# file and the issue happened again. This is the last part of the console log.

That's very helpful -- thanks! It looks like it's failing in this code. Could you provide the text of your project's .vscode\tasks.json file? I'm wondering if the file is empty or the JSON is malformed.

DustinCampbell picture DustinCampbell on 22 Dec 2016

Hi. This is the content in my tasks.json. It was added by vscode.

    // See http://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "0.1.0",
    "command": "dotnet",

            "args": [
                "server"
            ],
            "isBuildCommand": true,
            "problemMatcher": "$msCompile"
        },

    ]
}

I think I see the problem. Please delete the comments and try again.

DustinCampbell picture DustinCampbell on 22 Dec 2016

Problem solved. It was the comments in tasks.json

raitoaez picture raitoaez on 22 Dec 2016

Great! I'll code up a solution and release an update to the extension later today.

DustinCampbell picture DustinCampbell on 22 Dec 2016

That was quick! Removing the comments fixed it for me too. 馃憤

Glad to hear it. Working on a fix... :smile:

DustinCampbell picture DustinCampbell on 22 Dec 2016

OK. I've merged the fix for this in our release branch. We'll release 1.6.1 later today with this fix. Thanks to everyone for your help!
