Hi,  
I am using [Elasticsearch.Net](http://Elasticsearch.Net) and Nest Nuget Packages. version 6.7.0 for both.  
I have configured the server at localhost:9200/#/  
I have also created indexes.  
Now, while searching I am getting an exception.

Elasticsearch.Net.UnexpectedElasticsearchClientException: „Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Int64' because the type requires a JSON primitive value (e.g. string, number, boolean, null) to deserialize correctly. To fix this error either change the JSON to a JSON primitive value (e.g. string, number, boolean, null) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object. Path 'hits.total.value', line 1, position 115.”

I have followed this tutorial:  
[https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/nest-getting-started.html](https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/nest-getting-started.html)

Please help in resolving this issue.

Thanks,

It sounds like you may be running Elasticsearch 7.x version and using NEST and [Elasticsearch.Net](http://Elasticsearch.Net) 6.7.0 to communicate with it. The 6.x versions of these libraries are not compatible with Elasticsearch 7.x; you should use NEST and [Elasticsearch.Net](http://Elasticsearch.Net) 7.x to communicate with Elasticsearch 7.x. There is currently a [7.0.0-alpha2 prerelease available on Nuget](https://www.nuget.org/packages/NEST/7.0.0-alpha2) and we're working to move towards a GA release shortly
