Question: I have [this](http://dl.dropboxusercontent.com/s/kif6wdoq5txebcr/download?dl=1) file, and I have absolutely no idea what kind of file it is.

When I open it in Notepad++ it reads as

```
ð    X      döS   

```

**or**

How can I figure out what language this is?

Answer: 
you might want to try using netmq (<https://github.com/zeromq/netmq>), is a 100% C# port of zeromq and might be easier to use then calling pinvoke.
Have you created a dllmap in your config? 

```
<configuration>
    <dllmap dll="libzmq.dll" target="/usr/local/Cellar/zeromq/4.0.4/lib/libzmq.dylib"/>
</configuration>

```
