You can download the Abodit Natural Language Engine using Nuget. This will install just the core module.
You can add other Nuget packages under the Abodit name including a core WordNet package, an extended WordNet package and an Autofac integration package. The WordNet packages include over one hundred thousand words together with definitions and a complete network of meanings. To use the engine you will need to create an application and a separate rules assembly. The easiest way to see how to do this is to try the 'Hello World' sample which you can get from GitHub.
