VsCode/Omnisharp doesn't respect excluded folders from project.json

Environment data

dotnet --info output: .NET Command Line Tools (1.0.0-preview1-002702)

Product Information: Version: 1.0.0-preview1-002702 Commit Sha: 6cde21225e

Runtime Environment: OS Name: Windows OS Version: 10.0.10586 OS Platform: Windows RID: win10-x64

VS Code version: 1.2

C# Extension version: 1.1.5

Steps to reproduce

Download either protractor or create .cs file under folder that is excluded in Project.json from compile.

  "buildOptions": {
    "emitEntryPoint": true,
    "warningsAsErrors": true,
    "preserveCompilationContext": true,
    "compile": {
      "exclude": [
        "node_modules", 
        "obj", 
        "bower_components", 
        "wwwroot",
        "typings",
        "bin"
        ]
    }

Expected behavior

Vscode doesn’t show errors in “!” menu from excluded files.

Actual behavior

All errors are shown in files at excluded folders. Protractor in node_modules folder is pain because it contains lots of .cs files.

Workaround: exclude on top-level… "exclude": ["node_modules","..."], "dependencies": {

I don’t think we’re going to be addressing this issue for project.json-based .NET Core projects. Our focus has moved to better support for .csproj-based .NET Core porjects.
