Hi,  
I downloaded ElasticSearch Nest dlls ([Elasticsearch.net](http://elasticsearch.net/), AysncIO.dll) libraries . All binaries are targeted for platform x86 (Windows machine && 32 bit)

Is 64 bit platform supported in ElasticSearch Nest?  
Could you please guide me to download the 64 bit libraries??

Thanks,  
HPGP

All .NET client libraries are compiled with `AnyCPU`, which means

- If the process runs on a 32-bit Windows system, it runs as a 32-bit process. IL is compiled to x86 machine code.
- If the process runs on a 64-bit Windows system, it runs as a 64-bit process. IL is compiled to x64 machine code.

You can see the flags of the latest NEST 6.7.0 assembly using CorFlags:

```auto
corflags /nologo "C:\Users\russc\Downloads\nest.6.7.0\lib\netstandard2.0\Nest.dll"

Version : v4.0.30319
CLR Header: 2.5
PE : PE32
CorFlags : 0x9
ILONLY : 1
32BITREQ : 0
32BITPREF : 0
Signed : 1

```

`PE: PE32` and `32BITREQ : 0` and `32BITPREF: 0` means that the assembly was compiled with `AnyCpu` target.
