StackExchange.Redis failing to connect with Mono in Mac OS X

Question

I'm trying to run a very simple Redis client on Mono in Mac OS X with the following options:

var configOptions = new ConfigurationOptions() 
{
    EndPoints =
{
    { "localhost", 6379 },
},
ResolveDns = true,
KeepAlive = 180
};
StringWriter sw = new StringWriter();
ConnectionMultiplexer.Connect(configOptions, tw);

It fails to connect. Here is the trace:

localhost:6379,keepAlive=180,resolveDns=True

I've tried with and without ResolveDNS and specifying the IP address directly. Tried several ports as well. Server is running and is reachable by redis-cli.

StackExchange.Redis version="1.0.289" targetFramework="net45"

Redis-64 2.8.9

Update

StackExchange.Redis version="1.0.297" targetFramework="net45", same problem but different log

Answer 1

As others stated, StackExchange.Redis has problems connecting to the server on mono, and you have to build a custom assembly from the source, targeting Mono. So I created a nuget package from the mono build of the library using monobuild.bash. You can use it as a direct replacement for the original StackExchange.Redis on mono.

https://www.nuget.org/packages/StackExchange.Redis.Mono/

As we are using the package in our server application, I will be updating it regularly.

Answer 2

I had the same problem using the nuget package directly. I've cloned the StackExchange.Redis repo and created a new DLL with the included bash command for mono:

./monobuild.bash

Referenced the resulting DLL and it worked flawlessly on OSX with the exact code that you've placed on the question.
