Sdk: Analyze Code Coverage in VS2015 not working

[Ausm]

Steps to reproduce

When I create a test solution with a ClassLibrary project in the src folder, and a Test project in the test folder with the following project.json files, all tests/testrunners work just fine, but analyzing the code coverage in VS is not working.

ClassLibrary's project.json:

{
  "version": "1.0.0-*",

  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0-rc2-3002702"
        }
      }
    },
    "net452": { }
  }
}

Test's project.json:

{
  "version": "1.0.0-*",
  "testRunner": "xunit",

  "dependencies": {
    "xunit": "2.2.0-beta1-build3239",
    "dotnet-test-xunit": "1.0.0-rc2-build10015",
    "Test": "1.0.0-*"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0-rc2-3002702"
        }
      },
      "imports": [
        "dnxcore50",
        "portable-net45+win8"
      ]
    },
    "net452": {
      "dependencies": {
        "Microsoft.NETCore.Platforms": "1.0.1-rc2-24027"
      }
    }
  }
}

Expected behavior

To show me the code coverage.

Actual behavior

dotnet.exe has stopped working.

And the Tests output shows me:
------ Run test started ------
Discovering tests in '...\Test\Test\project.json' ["C:\Program Files\dotnet\dotnet.exe" test "...\Test\Test\project.json" --output "...\Test\Test\bin\Debug\netcoreapp1.0" --port 8005 --parentProcessId 7116 --no-build]
'test-xunit' returned '-532462766'.

dotnet --info output:

I tried to debug it in the dotnet-test-xunit, and added a Debugger.Launch(); in it's Main.
It's called when I discover/run the tests in any way, but not when I run "Analyze Code Coverage".

Ok, my fault.
See dotnet/sdk#5440

Simply add "Microsoft.CodeCoverage": "1.0.1" to the netcoreapp1.0 dependencies, and everything works fine.

The Test's project.json looks now like:

{
  "version": "1.0.0-*",
  "testRunner": "xunit",

  "dependencies": {
    "xunit": "2.2.0-beta1-build3239",
    "dotnet-test-xunit": "1.0.0-rc2-build10025",
    "Test": "1.0.0-*"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0-rc2-3002702"
        },
        "Microsoft.CodeCoverage": "1.0.1"
      },
      "imports": [
        "dnxcore50",
        "portable-net45+win8"
      ]
    },
    "net452": {
      "dependencies": {
        "Microsoft.NETCore.Platforms": "1.0.1-rc2-24027"
      }
    }
  }
}

I'm also seeing this but I'm just trying to get vanilla tests to run..

[xUnit.net 00:00:00.0597555] Skipping: Foundatio.Tests (no reference to xUnit.net)

I don't have any code coverage..

[niemyjski]

I think it's failing because Foundatio.Redis.Tests references Foundatio.Tests

I created a new issue: https://github.com/dotnet/cli/issues/3759

I ran into this issue as well, but your provided fix doesn't seem to be working.
Not sure what I am doing wrong here, or if there is some regression since RC2.

@jderus me too. How fix this bug?

@jderus me 3

[andriysavin]

@jderus Try adding "imports" section with one of package's supported TFM, e.g:

"imports": ["dnxcore50"]
