ElasticSearch Nest 5.0.1 throwing below exception, when called from Droid project, From Unit test everything works fine

Question

I am working on Xamarin Android using Nest 5.0.1 in NetStandard project.

Search api are called from a portable project.

When calling any Nest Search api via Unit test. It is working fine. But when the same api via Droid project getting below error.

var connectionPool = new SingleNodeConnectionPool( new Uri( "http://localhost:9200" ) );
SearchSettings = new ConnectionSettings( connectionPool, new HttpConnection()).DefaultIndex( "test-index" );
SearchClient = new ElasticClient( SearchSettings );

Can anyone help, what is missing. I have ensured that System.Net.Http is present in both Portable and Droid project.

Can you please open an issue for this: https://github.com/elastic/elasticsearch-net/issues. We'll need more detail on the issue, but it looks like the `HttpClientHandler` implementation in the Droid project has not implemented `MaxConnectionsPerServer` property — Russ Cam, Jan 27 '17 at 21:49

This was a bug, that is resolved by the ElasticSearch team.

One thing, i had to do is .ConnectionLimit(-1) on ConnectionSettings.
