Create a new console project in Visual Studio. Add a references to the Couchbase.dll, Enyim.Memcached.dll, Newtonsoft.Json.dll and RestSharp.dll assemblies found in the release zip file.
Visual Studio console applications target the .NET Framework Client Profile by default, so you'll need to update the project properties to instead target the full .NET Framework. If you skip this step, you'll have compilation errors.
