I'd like to add the code coverage metrics to our VSTS build. The solution is ASP.NET core with XUnit. Please advise on the steps.

if yes, then point me how to enable code coverage for the .net core projectsBoris Lipschitz– Boris Lipschitz2018-05-02 02:12:01 +00:00Commented May 2, 2018 at 2:12

Refer to these steps to enable code coverage for .NET Core XUnit test:
- Edit projects’ files (test and related project) to add DebugType property
for example:
<PropertyGroup>
<TargetFramework>netcoreapp2.0</TargetFramework>
<IsPackable>false</IsPackable>
<DebugType>Full</DebugType>
</PropertyGroup>
- Update Microsoft.NET.Test.Sdk package to latest version (change version value to 15.7.0)
- Add Visual Studio Test task to build definition and specify Test assemblies and Search folder
- Choose Specific location option in Select test platform using section
- Specify
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions\TestPlatformin Path to vstest.console.exe - Check Code coverage enabled option
- Specify
/framework:".NETCoreApp,Version=v2.0"in Other console options box

Thanks! I wonder if it works with Test assemblies should I "dotnet publish" first?

@BorisLipschitz Do not need.
Boris Lipschitz
You are right about no need to publish. However, it doesn't work:Data collector 'Code Coverage' message: Cannot find CodeCoverage.exe.. FileNotFoundException: No test is available in C:\agent_work\2\s\test\MyProj.UnitTests\obj\release\netcoreapp2.0\MyProj.UnitTests.dll. Make sure test project has a nuget reference of package "Microsoft.NET.Test.Sdk" and framework version settings are appropriate and try again.

I do have <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.7.0" />

What're tasks of your build definition? Can you share the detail log on the OneDrive? (Set system.debug variable to true, then queue build and share this log) Try to specify` **UnitTest.dll !**\obj**` (two lines) in Test assemblies input box.
