Asp.Net Web API outputcache with Redis not working

Question

Redis is running on windows (services -> Redis Server)
Web.config is configured

<caching>
 <outputCache defaultProvider="MyRedisOutputCache" enableOutputCache="true" enableFragmentCache="true" sendCacheControlHeader="true">
    <providers>
      <add name="MyRedisOutputCache" type="microsoft.web.redis.redisoutputcacheprovider" host="127.0.0.1" port="6379"accesskey="" ssl="false" />
    </providers>
  </outputCache>
</caching>

Output cache attribute is added to my Web Api controller

[CacheOutput(ClientTimeSpan = 60, ServerTimeSpan = 60)]
Caching is working, but Redis does not contain any key

redis 127.0.0.1:6379> keys * (empty list or set) redis 127.0.0.1:6379>
Also tried to register my custom output cache provider

public override string GetOutputCacheProviderName(HttpContext context) { return "MyRedisOutputCache"; }

Nothing helped :( Any idea?

I also have the same issue, if I run redis-cli monitor I only see bunch of GET requests but no SET at all. Strange! the same provider works just fine with a remote redis (eg. redislab), and the same redis installation is working great with other parts of the same application that uses StackExchange Redis client to store and retrieve data. — undefined

I finally was able to solve the problem by uninstalling an existing redis installation which became obsolete https://github.com/rgl/redis

If you installed redis from there, then read along...

I then installed redis-64 from https://chocolatey.org/packages/redis-64 and it worked perfectly.

Once installed via chocolatey, goto C:\ProgramData\chocolatey\lib\redis-64 on an administrative command prompt or powershell and run the following command to register redis as windows service

redis-server --service-install redis.windows-service.conf --loglevel verbose
then create a folder Logs (without this the service won't start)
run the service redis-server --service-start
