* Reworded and added to interface documentation
Fixed a few typos and reworded and added parts to the csharp interface documentation
* fix: used single backticks instead of triple backticks
Corrected syntax of interface. From Interface to interface (lowercase on first letter).
If the first letter on the word interface is uppercase, this will produce an error on Visual Studio stating that:
The type or namespace name 'Interface' could not be found (are you missing a using directive or an assembly reference?)
