Question: I have generated my xml coverage file as part of CI build on the TFS server using vNext 2015 build definition. How would one display the results in the TFS 2015 summary ? Either using the xml report or the html generated using the ReportGenerator.

Answer: 
You need to convert the results produced by OpenCover to a format which can be parsed by TFS.

One way to do this would be to use the [OpenCoverToCoberturaConverter](https://github.com/danielpalme/OpenCoverToCoberturaConverter) NuGet package.

Once you have that, you can use the *Publish Code Coverage Results* build step.

I have described the whole process on [my blog](http://codewithstyle.info/setting-up-coverage-reports-on-vsts-with-opencover/).
Currently, these customizations are not supported. You can't edit the displays in new build summary. However, you can [customize Code Coverage Analysis](https://msdn.microsoft.com/en-us/library/jj159530.aspx).
