Could you create the PR on branch features/4.3.0 please. Sorry should make clearer in the readme

@Francois-du-Plessis, @alhardy Any update on this? It's over a year.

Hey @Havret, the maintainer is a bit busy with life at the moment. Workaround we are currently using is to wrap the reporter type into a unique type:

/// <summary>
/// Empty wrappper class of InfluxDbMetricsReporter to create a uniquely typed reporter.
/// </summary>
internal class UniqueReporter1InfluxDbReporter : InfluxDbMetricsReporter
{
    internal UniqueReporter1InfluxDbReporter(MetricsReportingInfluxDbOptions options, ILineProtocolClient lineProtocolClient) : base(options, lineProtocolClient)
    {
    }
}

/// <summary>
/// Empty wrappper class of InfluxDbMetricsReporter to create a uniquely typed reporter.
/// </summary>
internal class UniqueReporter2InfluxDbReporter : InfluxDbMetricsReporter
{
    internal UniqueReporter2InfluxDbReporter(MetricsReportingInfluxDbOptions options, ILineProtocolClient lineProtocolClient) : base(options, lineProtocolClient)
    {
    }
}

Hey @Francois-du-Plessis, thanks for your suggestion. It requires some boilerplate registration code, but works like a charm.
