This C# sample demonstrates the use of the Google Cloud Natural Language API for sentiment, entity, and syntax analysis.

1. Follow the instructions in the root README.

2. Enable APIs for your project. Click here to visit Cloud Platform Console and enable the Natural Language API.

3. Open the solution file "Analyze.sln" with Microsoft Visual Studio version 2015 or later:

   • Google.Cloud.Language.V1 - Analyze.sln
   • Google.Cloud.Language.V1.Experimental - Analyze.sln

4. Build the Solution.

5. Run.

   The script will write to STDOUT the json returned from the API for the requested feature.

   For example, if you run:

   c:\> Analyze everything Santa Claus Conquers the Martians is a terrible movie. It's so bad, it's good.
   

   You will see something like the following returned:
