C# support not working after C# extension installed

[ghost]

• VSCode Version: 0.10.11
• OS Version: 10.11.3

Steps to Reproduce:

1. Download this file and open it with VS Code http://d.pr/f/1jczl
2. Check if there's intellisense.

If it doesn't have intellisense, it's not an editor. Might as well use textedit.

Did you install the C# extension? https://code.visualstudio.com/Docs/languages/csharp#_installing-c35-support

[ghost]

Yes it's installed

[Tyriar]

@Leocrespo and was vscode restarted after it was installed?

[ghost]

Yes of course. Have you tried downloading the file and opening it, I'm sure there won't be any intellisense.

[Tyriar]

Works fine for me. I'm on Windows 10 and had VS2015 installed before VSCode.

I haven't actually used the C# support before, one of the other devs might be able to help you out beyond this point.

[ghost]

I can do that too, that's not intellisense.

This is intellisense

@Leocrespo this might resolve your issue http://stackoverflow.com/a/29979730/1156119

1. There isn't any option for me to create a project.json or a solution. (amazing)
2. There is no "Open folder" command

[ghost]

All I want is to have basic intellisense on the file I posted, just as I do when I open it with VS. So I created a solution in VS2015.

then opened everything with VSCode and still no intellisense.

[Tyriar]

Visual Studio can generate sln files as you mention, VSCode cannot. VSCode typically relies on external tools or extensions for that kind of project scaffolding.

As for the project.json, it looks like this is created using the relatively new .NET Core and dotnet CLI which uses a more folder-based approach to C# development which is more inline with what VSCode was designed to work with (as opposed to project/solution-based).

So once the .NET Core is installed, you should be able to run this to generate a project.json:

dotnet new

And then this to run your application:

dotnet restore # install deps
dotnet run

When coming back to VSCode I ran into this OmniSharp issue related to VSCode not being able to find the globally installed dnx runtime #126 (comment)

Not sure why open folder is not there, it always has been for me (I don't use OSX though).

You can always run the command from the command palette:

1. Press F1
2. Type open folder
3. Press enter

@Leocrespo just want to point out that the example you show here would never work as your trying to write the script in the c# class root scope.
In this scenario Visual studio also fails to show intellisense too

Try this example project in vscode https://github.com/dotnet/core/tree/master/samples/helloworld

run dotnet restore in the root and you should get this:

i'm running vscode 0.10.11

@Leocrespo There is a Omnisharp log file (Cmd+L,L) Please paste its contents here.

This issue was moved to dotnet/vscode-csharp#114

There's no need to send logs or try any other steps, this problem takes 15 seconds to reproduce.
Just download this file, open it with VS Code and you'll see there's no intellisense

[jrieken]

as outlined by @pflannery here, what you trying to do isn't valid C# so you should not expect IntelliSense

[ghost]

It doesn't matter where you put the code, there's no intellisense.

VSCode, no intellisense

VS 2015, same file, here's the intellisense.

I can't Install C#...with ext install C# . nothing happened.

[Tyriar]

@yankun007 I believe it's quite large so it sometimes takes 30-60 seconds to download. Are you sure you waited long enough?

[dave-hillier]

I had this problem. I took the following steps and it started working again.

1. uninstall all the plugins
2. uninstall VSCode
3. reinstall and open the project in VS Code
4. reinstall the c#
5. still not working after reload
6. Restart & reopen

it started downloading Omnisharp and added some files to my project.

I think its unfair that this was closed, however, it looks like some kind of setup problem.
