This is because a new instance is created and the last instance is overwriting all the previous runs. Can this code come from a static class instead of a new instance each time the method runs:

string reportpath = projectPath + "com.seloger.reports\\AfficherTypeProjet-"+DateTime.Now.ToString("yyyyMMdd") +".html";

_report = new ExtentReports(reportpath, true);
_report.AddSystemInfo("HostName", "Kais")
    .AddSystemInfo("Environment", "PROD")
    .AddSystemInfo("User Name", "Kais KHALIFA");
_report.LoadConfig(projectPath + "extentReport-config.xml");

Example:

if (_report == null)
    _report = ExtentManager.Instance;

ExtentManager (http://extentreports.com/docs/versions/3/net/#helper-classes):

public class ExtentManager
{
    private static readonly ExtentReports _instance = new ExtentReports();

    static ExtentManager()
    {
        var htmlReporter = new ExtentHtmlReporter("Extent.html");
        Instance.AttachReporter(htmlReporter);
    }

    private ExtentManager() { }

    public static ExtentReports Instance
    {
        get
        {
            return _instance;
        }
    }
}

Thank you for your reply. Shouldn't this fix the issue? _report = new ExtentReports(reportpath, false) instead of true?

It may but I wouldn't recommend this in a parallel fashion as 2 threads writing to the same file may cause conflicts. You can make this block synchronized and it should work but a better way still is using the above approach.
