Unable to load DLL "libzmq"

1. Local,you can read the follow word

   PS, I found the solution to solve my error. When downloading ZeroMQ from NuGet in VS, there is actually a warning that I ignored at first. It says to manually copy libzmq.dll to output directory of the project besides reference of clrzmq2. After manually copy libzmq.dll to output directory, it is working now. 

2. Server(Windows server 2008 r2)

   This one,please make sure you already install the installer which name is "Microsoft Visual C++ 2010 Redistributable Package x86"

   Of cause,you can direct download from this link

   when you already install,please restart server.

   hope this can help you.
