如何从代码覆盖范围中排除异步委托

Question

我正在使用c＃dotnet core 2.1控制台应用程序。我的类具有[ExcludeFromCodeCoverage]属性，但是仍在考虑该类中某个方法内的异步委托进行代码覆盖。我正在使用Coverlet作为代码覆盖率生成器。如何排除异步委托？

[ExcludeFromCodeCoverage]
public class DuplicateDetectionService
{
   public virtual async Task ExampleMethod()
   {
        var retryPolicy = Policy
                 .Handle<SocketException>()
                 .Or<HttpRequestException>()
                 .WaitAndRetryAsync(5, i => TimeSpan.FromSeconds(5));
       await retryPolicy.ExecuteAsync(async () =>
       {
            //Some code which is included in code coverage
       }
   }
}
