Can't Find Rx Dump() Method

I've seen lots of answers on here and in various posts and tutorials on other sites where the Dump() method is used on an IObservable<T> sequence. However, when I try to use it, I get a ... does not contain a definition for 'Dump' and no extension method for 'Dump' ... Cannot resolve symbol 'Dump' warning from the compiler. Has it been removed from Rx, or am I missing a library?

Recommend to use LINQPad related nuget package (LINQPad officially provided), then you can use Dump() method of it.

LINQPad

For .NET core:

  • Install LINQPad.Runtime

For .NET framework 4 etc.

  • Install LINQPad

Sample code:

using System;
using LINQPad;
namespace Csharp_Dump_Test
{
    public class Program
    {
        public static void Main()
        {
            try
            {
                DoSomething();
            }
            catch (Exception ex)
            {
                ex.Dump();
            }
        }

        private static void DoSomething()
        {
            throw new Exception("Unable.");
        }
    }
}

Yes I agree with the comments that it exists in LinqPad, however you may write your own as in http://www.introtorx.com/content/v1.0.10621.0/07_Aggregation.html

public static class SampleExtentions
{
    public static void Dump<T>(this IObservable<T> source, string name)
    {
        source.Subscribe(
           i=>Console.WriteLine("{0}-->{1}", name, i), 
           ex=>Console.WriteLine("{0} failed-->{1}", name, ex.Message),
           ()=>Console.WriteLine("{0} completed", name));
    }
}
