Coverage report with blazor .razor file throws NativeCommandError

I cover a Blazor application with xUnit tests.
My generated report contains references to .razor files crashing the scanner :

.razor files should be treated as .cshtml files.

If I exclude **/*.razor from my coverage report it works and I’ve .cshtml files.

Full code and build script can be found here

To enable .razor file in the report remove <ExcludeByFile>**/*.razor</ExcludeByFile> from coverletArgs.runsettings

Hello Olivier,

SonarQube can only import coverage information on files it knows. By default, the .razor extension is not recognized by any language. In order to be able to import this information, you can add .razor to the list of HTML File suffixes, under General Settings > Languages > HTML (similar to how .cshtml are recognized by the HTML plugin).

Hope that helps.
