I would greatly appreciate if you could be so kind to give me some simple basic examples of source code in .Net (C#) of how to get News Analytics, News Sentiment Indices and Real-Time News data. Unfortunately for some reasons we cannot use C++ or Java, only .Net (C#). Thanks in advance.
Please refer to the RFA.Net tutorials page - Tutorial 8 covers the basic techniques require to consume the MMT_NEWS_TEXT_ANALYTICS domain which covers News etc.
At the bottom of the page you will also see a link to the MRN Data Model documentation.
