The library had been replaced by `LuzmoSDK. You can find the new package on the GitHub repo luzmo-official/luzmo-sdk-csharp.
You can use this C# project to interact with the Cumul.io API in order to create, modify or delete datasets, dashboards or push new data into the platform in a programmatic way.
See the Cumulio API/Example.cs file for examples how to create datasets or push data into the platform (triggering real-time dashboard updates).
See the EmbeddedCumulio project to see an example of how to use the API to securely embed dashboards in an ASP.NET MVC web application (with serverside pre-filtering of the data that the end-user can query).
The API documentation (available services and methods) can be found here.
