CacheCow error in WebAPI Global.asax

Question

I'm getting this error:

Method 'RemoveResource' in type 'CacheCow.Server.InMemoryEntityTagStore' 
from assembly 'CacheCow.Server, Version=0.4.12.0, Culture=neutral, 
PublicKeyToken=null' does not have an implementation.

I cant find any info on it. I've just tried installing CacheCow Server with nuget into a website I'm building, to try use etags for cacheing. The error occurs on this line:

var cacheHandler = new CachingHandler();

Any ideas?

Answer 1

I had to revert CacheCow Common (via nuget) from 0.5.0.0 to 0.4.14.0, then I had to update the web.config from this:

to this:

    <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />

  </dependentAssembly>

which seemed to resolve the error above.
